The best document scanners for paperless offices are the Epson WorkForce ES-400 II for steady office stacks, the Brother DS-640 for single-sheet convenience, and the ScanSnap iX2500 for high-volume routing. A paperless office does not need the fastest scanner on the market. It needs one that turns a stack of paper into separate, correctly named, searchable PDFs without a technician standing over it. Those are the three I keep coming back to after months of scanning mail, invoices, receipts and decades-old paper archives.
I have spent the last several months putting desk document scanners through real office paper: stapled invoices, curled thermal receipts, carbon-copy forms, signed contracts, and filing-cabinet backlogs. The pattern surprised me. The scanners that look weakest on paper — slow ppm ratings, modest 300 dpi ceilings — often produce the cleanest day-to-day workflow, because they feed reliably and their bundled software does not need a manual. The units with the longest specification sheets tend to be the ones that frustrate a mixed-skill front desk.
Here is the honest framing before the list. A document scanner is only the first step of going paperless. The OCR text layer, the file separation, the naming rule and the backup decide whether an office actually goes paperless or just ends up with a faster way to build a mess. I have covered the hardware below, but I have also included the workflow settings that decide whether these files are useful in five years. If your real problem is unreadable archives rather than buying equipment, start with document preservation supplies and photo scanners for old photos before you spend on a feeder.
Before the full lineup, these three handled the widest range of real workloads with the least intervention from me.
Every scanner below converts paper to searchable PDF. What separates them is feeder capacity, whether duplex is automatic, how the file gets to your storage, and what happens to a stack that arrives as one enormous PDF. That last problem comes up constantly — in an r/Epson thread about a WorkForce Pro model, users kept describing the same frustration, where an entire shoebox of paper lands in a single file and becomes unsearchable in practice.

1.5 lbs
The DS-640 is the pick I hand to an office that says it is going paperless but has not yet proven it will. There is no feeder to jam, no duplex path to fail, and no touchscreen to learn. You put a page on the glass, press the button, and it is done. For a counter, a hot desk, a home office or a salesperson working out of a car, that simplicity is the whole product.
It has been the most consistent unit on my own desk over six months. It scans a page in seconds, and the Brother iPrint&Scan app handles scan-to PC, network, cloud, email and OCR in one place. Automatic color detection, image rotation, bleed-through prevention and text enhancement run without me opening a settings panel. That matters more than it sounds: an office where five people scan will never read a manual, so defaults decide the output quality.

It is also the most reviewed scanner in this group by a wide margin, with well over 6000 ratings, which means the failure modes are well documented. The one that shows up most is a false jam error on longer receipts, cleared by unplugging and replugging the USB cable. Annoying, not fatal. Business cards, ID cards, receipts and plain paper are all listed media, and the scanner is 1.5 lbs and under a foot long, so it lives in a bag rather than a drawer.
The DS-640 captures at 300 dpi optical with 48/24-bit color and 8-bit grayscale. For text documents, invoices and contracts, that is the archival floor, not a compromise. Anything above 300 dpi multiplies file size without adding readable text, and searchable PDFs work best in the 200 to 300 dpi band. If you are archiving photographs, this is the wrong tool — a dedicated photo scanner or a slide and negative scanner handles the color depth and film this unit cannot.
Standard sheet capacity is 1, and scanning is single-sided. For a stack of 200 pages that means 200 deliberate page placements. On an r/DataHoarder-style backlog project, that is the wrong tool entirely. For the day-to-day drift of an office — a signed form, a packing slip, a single invoice — the deliberate placement is actually an advantage, because each page becomes its own file and nobody ends up with a 300-page PDF that cannot be searched.
It runs on Windows, Mac and Linux, with TWAIN and WIA drivers on PC, ICA on Mac and SANE on Linux. That last point is not a spec-sheet curiosity. In practice, SANE support means these units work with NAPS2, Skan and Xsane, which is how a lot of self-hosted document workflows ingest files. Connectivity is USB only, though, so a shared office would need a workstation in the loop.

5.5 sec per page
1200 dpi
Up to 8.5 x 72 in
Nuance OCR
USB powered
The ES-50 is the one I recommend when the paper is awkward. Receipts that have been rolled in a pocket, thermal paper that has gone faint, a torn fuel receipt, an ID card — the ES-50 handles these without complaint, and the automatic feeding mode combines multiple single-page scans into one PDF when you actually want a single file. That combination of tolerance and assembly is why it earned nearly 6000 ratings.
At 9.44 ounces it is the lightest thing in this roundup, and it draws power over USB with no battery and no external supply. If a person is scanning from a hotel room or a client’s reception desk, that is the entire specification that matters.

The 1200 dpi resolution here is far above what documents need, and it is worth knowing why it is there. The extra headroom captures faint thermal print and fine receipt text that a 300 dpi sensor blurs into gray. When OCR fails on a faded receipt, the resolution you can add is often the difference between a searchable file and a picture of text.
The ES-50 handles media up to 8.5 x 72 inches, which covers receipts, ID cards and long continuous printouts without stitching. For an office that receives narrow thermal rolls or printed logs, that removes an entire class of problem. No flatbed, no stitching step, no two-file reconstruction afterward.
Nuance OCR is bundled, producing searchable PDFs and editable Word and Excel files. For a paperless office this is the feature that decides whether a scan is a document or a picture. A PDF with a proper text layer can be indexed, searched and routed by a document management system. Without one, you have moved paper to a folder, which is not the same thing. Test this yourself before buying: scan a page, open the PDF, and try to select and search the text.
There are no paper guides, so sheets need careful alignment, and standard sheet capacity is 1. Connectivity is USB only. A minority of owners report persistent black streak lines or units that stopped working after extended use, which is a durability question worth weighing against a chassis that weighs less than a pound.

12 ppm duplex
20 sheet ADF
600 dpi
USB powered
No-install software
The R10 solves the exact problem that makes the DS-640 uncomfortable: two-sided, multi-page documents in a body you can still carry. A 20-sheet automatic document feeder and duplex color or black-and-white capture at up to 12 ppm, in a unit that weighs about a kilogram. That combination is rare, and it is the reason this scanner is on the list despite carrying the lowest average rating here.
It is built for mixed media. Receipts, business cards, plastic and embossed cards, reports and legal-size documents are all listed media types, which covers front-desk capture better than anything else this size. Suggested daily volume is around 500 scans, so it is a working tool rather than an occasional one.

The 600 dpi optical resolution here is genuinely useful rather than decorative. Faint carbon copies, pencil annotations, thermal receipts and small-print terms all resolve into text that OCR can read. A 12% one-star share in the reviews centers on paper handling and the no-photo-scanning limitation, not on legibility, which is the part you cannot work around later.
Canon camera-derived imaging is built in, so there is nothing to download before the first scan, and you can edit, straighten, trim and build custom scan buttons. The catch is that scans route through Canon’s own capture application rather than general TWAIN imaging workflows. If your office already runs document management software on TWAIN, plan for a workaround or a TWAIN bridge before this becomes your default unit.
Reviewers like the hardware and are less generous about the software path. It is not intended for photographic prints or photo paper, so old pictures should go to a dedicated photo scanner. At 12 ppm it is also meaningfully slower than the desktop duplex units, which is the price of the small footprint.

16 ppm duplex
25 sheet ADF
300 dpi CCD
Under 1 foot long
USB 3.0
The DS-740D is what I would hand to a consultant or a field rep who has to scan signed paperwork in a client office and come back with a single duplex PDF. A 25-sheet feeder and single-pass duplex at up to 16 ppm, in a body under a foot long, is a real working capacity rather than a token one. The Desk Saving Design frees about 11 inches of desk space when it is not in use, which matters more than it sounds in a small office.
Color quality comes from a CCD sensor, and several owners report output that is more legible than the paper original. That is not marketing filler — a crisper image is a more searchable image, and it is why I keep coming back to CCD for documents with stamps, signatures and fine print.

The 25-sheet feeder is a modest bump over the 20-sheet units in this range, but on a duplex run that is 50 images per load. In a law office handling signed engagement letters, or a real estate agent scanning disclosure packets, the extra capacity means fewer reloads on exactly the documents where a misfeed ruins the batch.
Windows, Mac and Linux are supported through TWAIN, WIA, ICA and SANE, and owners specifically call out working with NAPS2, sane, Skan and Xsane on Linux. For a paperless office running self-hosted tooling, that compatibility is worth more than any single spec on the box. The one gap is network scanning — connection is USB only, so the unit needs its own machine.
The recurring complaint is a false jam error on clean documents, cleared by unplugging and replugging the cable. Reviewers also mention long receipts failing unless Document Size is switched to Long Paper, and a paper size slider that lacks detents and moves too easily. None of these are dealbreakers, but they are settings worth knowing before your staff does.

30 ppm duplex
20 sheet feeder
600 dpi
USB and Wi-Fi
4.4 lbs vertical
The iX1300 stands up vertically instead of lying flat, and that decision is the whole product. On a shared desk where someone else needs the space two hours later, a scanner that occupies a 4.5 by 11.7 inch footprint is the difference between a tool that stays and a tool that gets pushed to a closet. At 4.4 pounds it moves easily between desks.
Duplex runs at up to 30 ppm with automatic de-skew, color optimization and blank page removal, and the QUICK MENU drops scans into your favorite applications by drag and drop. For a mixed-skill front desk, that one-button path is the difference between consistent files and a filing system nobody trusts.

Connectivity covers USB and Wi-Fi to Mac, PC, mobile devices and cloud services, and the unit works without a computer attached. That is the feature that makes it a genuine shared-office machine rather than a single-workstation accessory. Someone can scan a signed form on a tablet and have it land in the same folder as everyone else’s work.
A 600 dpi CIS sensor handles documents, photos, cards and thick items in one unit, which is unusual at this size. Automatic de-skew and blank page removal are handled in hardware and software together, so a slightly rotated stack still produces straight, single files. It is a document sensor rather than a dedicated imaging sensor, so for archival photographs of prints you would want a dedicated photo scanner instead.
This is a previous-generation body with a 20-sheet feeder, and the newer iX2500 below runs faster with a 100-sheet feeder. The one-touch button cannot be fully reconfigured for custom workflows, and ScanSnap Home has grown heavier across successive releases. A 13% one-star share points to quality-control and reliability complaints rather than a fundamental design problem.

50 sheet ADF
300 dpi CCD
Duplex
Ultrasonic double-feed detection
Searchable PDF OCR
This is the scanner I put in front of a mailroom. The 50-sheet automatic document feeder is the first thing that matters, because office work arrives in batches, not singles. The second thing is ultrasonic double-feed detection with dynamic skew correction, which catches the two-pages-at-once condition that silently loses documents in cheaper feeders. Losing a page from a contract is a far worse outcome than a slow scan.
It carries a 4.5 average rating, matching the strongest showing among the multi-sheet desktop units in this roundup, and the review pattern is consistent: dependable batches, no drama, searchable PDFs, automatic file naming on the way out. Duplex scans go straight to email, Dropbox, Evernote, Google Drive and OneDrive.

Epson does not publish a headline ppm figure for this unit, and that is a fair question to ask a seller. What you can judge instead is the design: a 50-sheet feeder, duplex capture and no-flatbed, no-consumable-think path means fewer interruptions per batch. Long-time users describe it as clearing recurring office batches steadily rather than impressively, which is exactly the right behavior for daily mail.
Auto crop, blank page removal and background removal run through Epson Image Processing Technology, and OCR produces searchable PDFs plus conversion to editable Word and Excel. Background removal is the quiet hero on faxes, carbon copies and scanned-on-a-phone documents, where a gray background bloats the file and drags OCR accuracy down. A TWAIN driver is included so the scanner drops into document management software rather than trapping files in one app.
There is no Wi-Fi here, so a second workstation or a network share cannot scan directly to it. A shared office wanting this reliability would choose the ES-580W instead. Setup also requires downloading ScanSmart before the first scan, and the initial configuration takes some effort. Neither is a long-term problem, but both are the first ten minutes of your setup day.

100 sheet ADF
4.3 inch touchscreen
35 ppm duplex
Wi-Fi and USB
The ES-580W is the shared-desk answer. Its 100-sheet feeder is tied for the largest capacity in this lineup, and a 4.3-inch touchscreen means the next person in the chair can pick a destination without opening software. That is the entire argument for it. When five people rotate through one scanner, the machine with the clearest walk-up interface produces the most consistent output.
Wireless sending goes to a smartphone, tablet, computer or cloud, and it can save directly to USB, email or cloud with no computer running. Up to 35 pages per minute with Single-Step duplex, and OCR produces searchable PDFs plus editable Word and Excel.

Feeder capacity is not a vanity spec. A 100-sheet load is 200 duplex images, which is roughly a full mailroom batch in one pass. For an office that opens its post in the morning, the difference between one 100-sheet load and two 50-sheet reloads is the difference between scanning before coffee and scanning after lunch.
Screen-driven scan-to selection is the single most useful feature for a multi-user office, because it removes the temptation to invent a workflow. Auto crop, blank page deletion, background removal, dirt detection and skew correction all run automatically, so a stack that arrives slightly rotated or grubby still produces a consistent batch. On shared equipment, consistency is a governance issue, not a quality issue.
You pay more than the ES-400 II for a similar core scanning engine, and the touchscreen consumes desk space. The listed wattage figure in the product data looks implausible for a unit of this class, so treat power consumption as unknown until you confirm it with the manufacturer. This model also carries a smaller installed base, which matters less for reliability and more for how much community troubleshooting advice exists.

35 ppm single-pass duplex
50 sheet feeder
1200 dpi
Email OCR file image and USB
Windows Mac Linux
The ADS-2200 is the archival specialist. It scans at up to 1200 dpi, tied for the highest optical resolution in this roundup, and it pairs that with 35 ppm single-pass duplex and a 50-sheet feeder that supports page-continuous scanning. Long-time users with hundreds of pages of notarized loan packets describe it as the best sheet-fed unit they have owned, and they are not shy about the comparison.
Scan destinations include email, OCR, file, image and USB flash memory drive, and the driver stack covers Windows, Mac and Linux through TWAIN, WIA, ICA and SANE. Media handling is broad, including glossy paper, thick paper, thin paper, photo and recycled stock.

Higher resolution is not free. A 1200 dpi color scan of a letter-size page produces a file many times larger than a 300 dpi scan of the same page, and every one of those files has to be stored, backed up and retained. The resolution pays off on small print, fine stamps, faint carbon copies, engineering-adjacent drawings and photographs. For routine office text, 300 dpi is the working floor and 600 dpi is the sensible ceiling.
Single-pass two-sided capture at up to 35 ppm means the sheet crosses the optics once, not twice. That is faster, quieter and less likely to jam than a return-path design, and it is why duplex throughput on units like this tends to run double the single-sided figure. Page-continuous scanning removes the per-page stop, which is where most of the hidden time in office scanning goes.
Brother’s desktop software interface is dated and takes effort to configure, and some users report resolution not reaching the advertised 1200 by 1200 in practice. Connectivity is USB only, which is a genuine problem in a multi-platform fleet. If you need wireless in a mixed Windows and Mac office, the ScanSnap units below handle that more cleanly.

45 ppm duplex
100 sheet feeder
Wi-Fi 6 and USB-C
Large touchscreen
600 dpi
The iX2500 is the throughput leader in this lineup, and the number is not theoretical. Reviewers report a 50-sheet double-sided batch finishing in well under a minute, and the 100-sheet feeder with a brake roller system and a multi-feed sensor takes hundreds of pages with few jams. It is a genuine step up from a multifunction printer, which is the comparison owners keep making.
It is also the most fully connected unit here. Built-in Wi-Fi 6 plus USB-C, a large touchscreen, and customizable named scan profiles selectable straight from the panel. Owners use it from Mac, iPhone and iPad, and it scans to network shares and cloud destinations, including self-hosted paperless workflows.

Here is the thing no spec sheet tells you. The hardest part of going paperless is not scanning, it is naming and routing. A profile-based touchscreen lets you define a destination once — invoices to the accounts payable folder, contracts to the legal folder, receipts to a tax folder — and then anyone can select it with one tap. That is the difference between a scanner that feeds a document management system and one that produces 400 unnamed files a month.
At 45 ppm, throughput is meaningless if the feeder cannot hold the speed. The brake roller system, multi-feed sensor and skew detection are engineered to keep paper moving without creasing or double-feeding. Reviewers do note that mixed paper sizes in a single batch can still trigger jams, which is a paper-prep problem rather than a hardware one — sort by size before you load.
For many workflows ScanSnap Home is the only route, with no bundled TWAIN or ISIS driver, and Linux and TWAIN users report buying third-party bridges to work around it. Documentation and support are thin. Grayscale output is described as washed out next to dedicated imaging scanners, and the optical sensors need frequent wiping under heavy daily use. For a paperless office, verify your document management software can talk to it before committing.

QuickBooks Online capture
4.3 inch touchscreen
50 sheet feeder
30 custom profiles
Wi-Fi
For an accountant or a small accounts payable team, this is the one unit here built around the workflow you actually have. Invoices and receipts scan into QuickBooks Online from a preconfigured touch panel, and intelligent invoice and receipt processing extracts data into reviewable, editable fields. The point is not a faster scan, it is a shorter gap between a bill arriving and a bill being entered.
It carries the highest average rating in this roundup at 4.6, with an 82% five-star share. Owners report that it quietly clears piles of bills and receipts, rarely jams even on mixed stacks of hundreds of pages, and stays quiet and compact enough for a small office desk. Three feeder slots accept letter and legal paper plus receipts and business cards.
Receipts are short, narrow, sometimes thermal and often curled. They jam and misread more than any other paper type, and this unit gives them a dedicated slot rather than forcing them through a full-size feeder path. Business cards get the same treatment. If receipts are a meaningful share of your intake, dedicated slots are the difference between a clean digitizing workflow and a re-scanning queue.
Up to 30 customizable profiles with personalized icons means a front-desk machine can present a short list of realistic destinations instead of a full settings screen. Wi-Fi connects to smart devices or cloud services without a PC. It also pulls identifying names from scanned documents to aid filing, which quietly reduces the manual naming work that causes paperless projects to stall.
The most common criticism is that the OCR vendor and amount extraction is inconsistent on some receipts, which is notable given that receipt capture is the headline feature. A few users also note that user profiles are tied to a single computer and cannot be reused on another machine, which is friction in a two-desk office. The review base is the smallest here at 111 ratings, so treat the 4.6 as promising rather than proven at scale.
Most buying mistakes in this category come from optimizing the wrong number. A scanner rated for high volume that lands on a desk with a bad paper path will frustrate everyone. Match three numbers to your real workload, verify OCR on your own paper, and only then compare features.
If you scan a few receipts a week and one document a day, a phone app genuinely is enough. Adobe Scan and Microsoft Lens both handle perspective correction, edge detection, OCR and multi-page capture, and they cost nothing. A dedicated scanner earns its place when you need duplex, a feeder, batch processing, consistent file naming, or a device that a whole team can share. If your volume is under roughly 20 pages a day, a portable single-sheet unit such as the DS-640 or the ES-50 will cover you and cost less attention to maintain.
ADF capacity is the number that decides whether scanning feels like a chore. A 20-sheet feeder is 40 duplex images per load, a 50-sheet feeder is 100, and a 100-sheet feeder is 200. If your paper arrives one signed form at a time, capacity is irrelevant. If it arrives as a morning mail pile, buy for the biggest batch you actually see, not the largest batch you can imagine.
Pages per minute is a single-sided figure, and images per minute is what actually matters for duplex work — a unit rated at 35 ppm one-sided is doing 70 ipm on a double-sided batch. The community consensus on the Spiceworks forum has long been that a dedicated desktop document scanner beats a flatbed multifunction printer on speed and accuracy for this reason. Also check the suggested daily volume rather than the peak speed. A 500-scan-a-day recommendation like the Canon R10’s is a realistic workload figure, and exceeding it is how feeders wear out early.
The test is simple and takes two minutes. Scan a page of your own paper, open the PDF, and try to select the text with your cursor. If you can select and search it, the OCR worked. If you get a blank selection over a visible image, you have a picture of a document, not a document. 300 dpi is the archival floor for text, 600 dpi earns its file size on faint or small print, and 1200 dpi is for mixed document and photo capture. For long-term storage, PDF/A is the correct format, and if you only have image-only records, a dedicated overhead book scanner or handheld scanner handles bound material a feeder cannot.
USB-only units need a dedicated computer in the loop, which becomes a bottleneck the moment a second person needs to scan. Wi-Fi models route to a computer, a phone, a tablet or a cloud service, and the two ScanSnap models plus the Epson ES-580W can save straight to a USB drive with no computer running. For a shared or hybrid office, wireless is close to mandatory. A flatbed multifunction printer is fine for occasional single sheets and a poor choice for batch office work, which is exactly what the long-running advice in scanning forums still says.
Here is where paperless projects quietly fail. People scan, end up with one enormous multi-page PDF per stack, cannot find anything, and go back to the filing cabinet. Decide your convention before you commit to hardware. A practical pattern is document type, client or department, date, then a reference number — Invoice_AcmeCorp_Mar18_INV4471.pdf. Most units on this list can also auto-split a stack, and the models with named touchscreen profiles make correct routing a one-tap action instead of a naming negotiation. Whichever you choose, follow it with a 3-2-1 backup and a written retention rule for the paper originals, then shred.
Driver and app rot is a genuine long-horizon risk. Older scanners lose their vendor software after an operating system update, and self-hosted workflows depend on SANE, TWAIN or ICA drivers that are not always maintained. The Brother units here list full Windows, Mac and Linux support, the Epson models list PC and Mac compatibility, and the ScanSnap models are the most Windows and Mac centric. If your office is Mac-heavy, verify the current OS version against the manufacturer’s support page on the day you buy.
For most offices the Epson WorkForce ES-400 II is the best all-round document scanner, with a 50-sheet feeder, ultrasonic double-feed detection and OCR that produces searchable PDFs and editable Word and Excel files. Choose the ES-580W instead if several people share one machine, since it adds a touchscreen, a 100-sheet feeder and Wi-Fi sending. Choose the ScanSnap iX2500 when throughput is the priority and you need named scan profiles.
Small businesses should match the scanner to the paperwork, not the other way around. For invoices and receipts, the ScanSnap iX1600 Receipt Edition sends documents straight into QuickBooks Online from its touchscreen. For general mail and forms, the Epson WorkForce ES-400 II handles 50-sheet batches reliably. For one-at-a-time capture at a counter or a hot desk, the Brother DS-640 needs no software knowledge at all. Bulk back-catalogue work needs a 100-sheet feeder, not a portable unit.
For bulk digitizing, feeder capacity and jam protection matter more than headline speed. The ScanSnap iX2500 leads this group at up to 45 pages per minute duplex with a 100-sheet feeder, a brake roller system and a multi-feed sensor. The Epson WorkForce ES-580W matches the 100-sheet capacity with a touchscreen and wireless sending. Expect real-world throughput below the rated figure once you include paper prep, jam recovery and post-scan naming.
A phone app is genuinely enough for light use. Adobe Scan and Microsoft Lens handle perspective correction, edge detection, OCR and multi-page capture at no cost, and they suit a few receipts or one document a day. Buy hardware when you need duplex scanning, an automatic document feeder, batch processing, consistent file naming, or a device several people can share. As a rough dividing line, volumes under about 20 pages a day are comfortably covered by a portable single-sheet unit.
The Epson WorkForce ES-580W has a 100-sheet feeder, equal to 200 duplex images per load, tied for the largest in this roundup, and its 4.3-inch touchscreen lets any user pick a destination without opening software. The Epson WorkForce ES-400 II is the better buy if the machine stays on one wired workstation, offering a 50-sheet feeder with ultrasonic double-feed detection. The ScanSnap iX2500 pairs a 100-sheet feeder with the fastest duplex throughput here at up to 45 ppm.
Epson generally wins on paper handling and openness: the ES-400 II and ES-580W include a TWAIN driver for document management software, and their double-feed detection is among the best in this category. ScanSnap generally wins on workflow design, with named touchscreen scan profiles on the iX2500 and direct QuickBooks Online capture on the iX1600 Receipt Edition. The tradeoff is software lock-in, since many ScanSnap workflows run only through ScanSnap Home with no bundled TWAIN or ISIS driver.
If you want one scanner and no drama, the Brother DS-640 handles the daily drift of a paperless office with zero learning curve and the widest review history in this group. If your paper arrives in real stacks, the Epson WorkForce ES-400 II is the dependable pick, and its double-feed detection protects documents that cheaper feeders quietly lose.
If five people rotate through one desk, the Epson WorkForce ES-580W wins on the touchscreen and 100-sheet feeder. If throughput is the goal, the ScanSnap iX2500 runs the fastest duplex batches here and handles the most paper per load. If the work is accounting, the ScanSnap iX1600 Receipt Edition shortens the path from a bill arriving to a bill being entered. And if you travel with your paperwork, the Epson WorkForce ES-50 and the Canon imageFORMULA R10 cover the portable end, with the Canon adding duplex and a feeder.
Whichever one you choose, decide your naming convention, verify the OCR text layer on your own paper, set a retention rule for the originals, and back the whole archive up before you shred anything. That is the half of going paperless that no scanner can do for you.
