Brother ADS-4700W Professional Desktop Scanner with Fast Scan Speeds, Duplex, Wireless, and Large Touchscreen, White

Works with Linux over USB and over the network. This thing is so feature-packed it's hard to decide where to start. It exceeded my expectations! It's clearly designed to work in a small office with multiple users. It works well over a network, it even enables multiple levels of encryption -- it can transfer over SSH (SFTP) by setting up the usual SSH authorized keys AND it can encrypt the (PDF) files. It allows you to set up HTTPS for a secure network-based administration interface. It can be configured to work with your users via your LDAP/Active Directory system. It also keeps counters for documents scanned. The network configuration interface is a bit clunky at times -- setting up the scan profiles is time-consuming -- I can't copy one scan profile into another and then change one setting (like the destination directory and file name). Allows you to set up "shortcuts" on the LCD panel so it takes as few as two taps to start scanning. All of that said, I've had a few cases where the auto-deskew feature failed. The scanning element got dirty somehow (dust I suspect) and the resulting scans had vertical bands -- it would be nice if there was some way to detect that (an IR sensor like that used in some negative scanners perhaps?) and pause the scans or even auto-clean itself. I was really hoping to use the OCR feature but that seems to require Windows integration -- the Linux proprietary drivers are limited to the old SANE standard as best I can tell. The speed with which it scans at reasonable, non-photographic DPIs and the reliability of the automatic document feeder are excellent. It jams rarely, jams are easy to clear, become easy to anticipate, and after a jam it allows you to continue scanning rather than forcing you to start all over. It do wish it accepted somewhat wider pages as some things are a few inches wider than 8.5 inches.

My wife and I bought this to replace the scanner that was on one of those cheap little all-in-one deals. You know the kind: It has a scanner on the top that accepts a single (one-sided) page at a time and really works best for scanning photos ... not documents. It died, and so we started shopping for a replacement.See, the problem is that we scan a _LOT_ of documents. We homeschool our (three) children and I'm a big IT Geek (a programmer) meaning I like having all of my paper documents backed up on my (very nice, and very expensive) server.Scanning has always been a real pain and a chore for us. One side of one sheet of paper at a time. Moreover, we had to drag out a USB Key so that we could scan each document to it, then move that to one of our PCs so that we could pull the document off of the USB Key and move it onto the server. A real chore that was super time consuming because of all of the manual intervention involved.This scanner has absolutely everything that I wanted:1. It is WiFi Capable (and offers manual configuration instead of only WPS - this is a real gem, as I don't use a store-bought router, and my Ubiquiti Access Point absolutely does not offer WPS WiFi configuration!).2. It can scan directly to a Network Share. Oh sweet loving heavens, I cannot tell you how much time this single feature alone has saved me in moving files off of USB Drives and onto my Network Drives.3. It is lightning fast. Seriously, with it's other features I can just turn the scan on and walk away - which is amazing - but this sucker is so fast that ... well, you'll see.4. It just works. Very - very - minimal setup even for me, and I'm betting my setup is far more advanced than your average user. I set up multiple profiles for one-button scanning of different document types. It will save them automatically to the correct network drive based on the profile for all of our document types based on just one button. Default settings for how it scans and saves each page are configured, and I can modify them prior to initiating a scan job easily and intuitively.Let me give you the best example that I can of how wonderful this little machine is. Among all of our homeschool <stuff>, we have text books, answer books ... and test books. I used our History test book as a trial case: It had 60ish (double-sided) pages, wherein each page equaled a single test (small test, kind of stuff we hand out weekly to the kids). The settings I used were to scan each double-sided page as an individual PDF document (so we'd have one PDF for each page - or roughly 120 PDFs at the end) and save them all to the predetermined network drive.With our previous scanner, we could scan 5-10 pages before it would just start crapping out on us and telling us the USB Drive was full (it wasn't). And it would take ages.I sat the entire 60ish pages into the scanner, hit a couple of buttons, and somewhere around 60 seconds later (I didn't actually time it, I didn't think to) it was done. No muss, no fuss, and I now have 115 PDFs in my network share ready for use.It ain't cheap, but we will absolutely get our money's worth out of this thing. If you are looking to scan documents (not pictures), scan a lot of them, not have to hassle with configuration, setup, fiddling with USB Keys all the time, and for the thing to just work no matter what you throw at it ... then this little guy will do the job.Cannot stress enough how happy I am with this thing.
