The AcerScan 620UT is a single-page USB color scanner.
It can be made to work with Linux, although some tinkering is required because of the proprietary firmware driver file which has to be uploaded each time the scanner is turned on. The firmware file must be copied from the manufacturer's driver set and SnapScan (Linux scanning software) must be configured to upload it, which fortunately is pretty easy.
- Get a copy of the scanner's driver (for any OS, as far as I can tell). This will contain .bin files, which are the firmware for various versions of the scanner. (Ours was U64V120.bin.)
- Stash all the .bin files (or, if you know which one is the right one, just that one) in /usr/share/sane/snapscan
- edit /etc/sane.d/snapscan.conf so that the "firmware" line refers to the .bin file which is correct for your scanner.
- If you don't know which one, then try each one -- make the edit, save snapscan.conf
- After modifying the snapscan.conf file, you will probably need to turn the scanner off and then back on again (this tells SANE that it needs to re-send the firmware).
- Run sane-find-scanner to see if communication with the scanner has been established.
- If that seems to have happened, then run this as a quick test:
- <bash>scanimage -x 100 -y 100 --format=tiff >image.tiff</bash> When this command doesn't give an error, you've got the right one, and regular GUI scanning applications should now work.
