Hi I installed Ubuntu 20.04 on my PC and I try to get the scanner run with xsane according the instructions of the wiki by ubuntuusers.de. There may be several problems.
1. Following the instruction by the wiki firmware esfw52.bin is installed. When I start xsane-Scan, there is following information "Cannot start scanner. Fault when I/O process. This was initially the main theme to be resolved. 2. Further I am now unsure if I use the correct firmware esfw52.bin. The reason is misleading informations by sane-project: According to http://www.sane-project.org/sane-backends.html#S-EPSON2 my scanner is unsupported. Cited: Perfection 3490 PHOTO USB 0x04b8/0x0122 Unsupported supported by the epkowa backend plus non-free interpreter According to http://www.sane-project.org/sane-mfgs.html#Z-EPSON firmware esfw51.bin is required and the status is good. Cited: Perfection 3490 PHOTO USB 0x04b8/0x0122 Good Requires firmware esfw51.bin I did not find a source of the firmware esfw51.bin for my scanner. What citation is correct? Is the second citation http://www.sane-project.org/sane-mfgs.html#Z-EPSON the actual version, is it correct and what firmware is required. If it is esfw51.bin, please give a source for this software. Please first answer the second question. The first item may be more complex, but if you have an idea, I would like to hear it. Yours thank you wthiel
