Short Reviews of the Selected
Let’s have a look at some of the salient features of each one.
This is a sheetfed scanner with a single pass duplex scanning mechanism. Basically, unlike the flatbed scanners, this can only scan loose sheets, business cards, envelopes etc.
As such it sports a 50 Sheet Automatic Document Feeder and has a scanning speed of 35 pages per minute.
This is fairly fast compared to an average scanner and amazingly fast when you compare this to an average flatbed scanner.
A scanner like this would only make sense if you have a huge scanning volume.
Besides that, it also has several other great features like a robust OCR for creating editable text files out of scans as well as USB thumb drive support.
Unfortunately, this isn’t a cheap scanner when compared to conventional flatbed scanners. It also lacks WiFi – but that is something most scanners lack at this price range.
All in all, if you need a fast, dedicated sheetfed option for large volume scanning, then this is the best single pass duplex scanner in our opinion.
If you want a high speed sheetfed scanner like the Brother ADS-2200 above, but you also want the WiFi capability, then this scanner stands out the most.
WiFi capability is an excellent feature for scanners especially if you work in an office group. With WiFi scanning, you can scan directly to you particular PC in a work-group without manually connecting your PC to the scanner via the USB.
It is also great for personal use since you can place the scanner whereever you want and even carry it around with you to scan documents in, perhaps, your attic.
On top of the WiFi interfacing, it also supports WiFi Direct as well as NFC. With this you can scan directly to your mobile devices like cell phones or tablets.
Other than that, like the the Brother ADS-2200 above, this too features a 50 sheet Automatic Document Feeder with a speed of 35 pages per minute.
Again, sheetfed scanners have a limitation that they can only scan loose sheets and cards. Unlike with the flatbed, you cannot scan irregular objects or bound books.
Unfortunately, it does not support scanning to thumb drive or SD card.
Basically, Epson WorkForce ES-500W is a robust WiFi enabled option for those who are looking for the best single pass duplex scanner with high speed and more network connectivity options.
This is a compact scanner that you can easily carry around with you in your backpack. It also occupies very little physical space on your desk space and thus can make your workspace less cluttered.
It is NOT the fastest scanner around nor the cheapest, however, the portability feature makes it shine among the rest.
It has a scanning speed of 25 pages per minute with double sided scanning. It also has a small and a rather convenient 20 page automatic document feeder.
Besides its compactness, this scanner is loaded with other useful features.
For starters, it offers WiFi which in itself is a highly lucrative feature. On top of that, not only does it support scanning to mobile devices, it also has support for scanning to thumb drives.
Finally, compared to the previously two scanners mentioned here, it even has a convenient touch screen with GUI for ease of use.
The only downside to this scanner is that despite being a portable scanner, it is NOT battery operated. You have to have it connected to your computer or a power source.
In the end, if portability is what you seek, then this option stands out as the best single pass duplex scanner for personal and office use.
We highly recommend this scanner for both your personal as well as office use. This is one of the most versatile scanners in the market. Why?
Epson DS-1630 offers both a flatbed as well as a sheetfed ADF scanner.
The ADF scanner has a 50 sheet capacity with single pass duplex scanning as at a speed of the 25 pages per minute.
While you can use the ADF for loose sheets, cards and stacks of documents, you can use the flatbed for books, odd and delicate documents.
The added functionality of a flatbed scanner is an excellent feature for artists and photographers as well who cannot risk damaging their masterpieces via the ADF – ADF CAN sometimes JAM!
Besides that, for a versatile scanner, not only is it budget friendly, it also has one of the best OCR software.
Unfortunately, it is lacking in terms of connectivity. While it does offer Ethernet, it lacks WiFi as well as Thumb Drive support.
All in all, Epson DS-1630 is a rare flatbed ADF specimen and thanks to it versatility it could well be the best single pass duplex scanner for many.
The idea behind this machine is simple: why only get a scanner, when you can get a scanner AND a printer at a much cheaper price tag?
This device is loaded with specs!
The scanner alone is an ADF with a capacity of 35 sheets and it can scan with a single pass both sides.
Beyond that, the scanner is a wide format scanner and thus can scan up to A3/Tabloid sized sheets.
Moreover, it has one of the most robust connectivity options including WiFi, WiFi Direct for direct printing via mobile devices, and Ethernet.
The printer is fairly great as well. While the printing operating cost is rather high, it is still a feature worth having. Plus, it can support printing of large format 13″ by 19″ sheets – which is rare even for standard printers.
Finally as an AIO device, it also includes a Fax machine. You must note that NOT ALL AIO printers feature a fax machine.
All in all, if you came here looking for an AIO device, then this certainly should be on top of your list.
Here we looked at the best single pass duplex scanners. The key thing to note here that the single pass mechanism comes in may types of scanners.
You can also find this on portable scanners like the Brother ADS-1700W.
The device you choose will depend upon what you value the most i.e speed, portability or versatility.
How expensive a device is depends on the amount of features it has. For example a WiFi capable scanner will be almost always more expensive than its Non WiFi counterpart.
