Epson 3490 scanner


Hi,

Everything was OK on Slackware 11.0, but there is a problem with 12.0. On 11.0, I didn't need an Epson *.bin firmware so
I comment # firmware /usr/share/sane/snapscan/your-firmwarefile.bin in /etc/sane.d/snapscan.conf.

1/ My user is in the scanner group.
2/ bash-3.1$ sane-find-scanner -> found USB scanner (vendor=0x04b8 [EPSON], product=0x0122 [EPSON Scanner]) at libusb:1:3
3/ bash-3.1$ scanimage -L -> device `snapscan:libusb:1:4' is a EPSON EPSON Scanner flatbed scanner
4/ xsane message error : [snapscan] download_firmware: No firmware entry found in config file snapscan.conf.

Does anybody knows how to make my Epson 3490 work without Epson binary firmware?

Thanks,
--

Since you say that you don't need the firmware, you apparently don't understand what it is.

The firmware is software that runs inside the scanner (not in the computer). Without the firmware, the scanner will not work.

I know what a firmware is and the file /etc/sane.d/snapscan.conf says "firmware". So the sane team probably "don't understand what it is"... With 11.0 it was possible to use my Epson 3490 without the Esfw52.bin Epson binary file ; the is not possible with 12.0.

You need to load the firmware file, which came with your scanner on the installation disk. Epson has decided that the firmware is proprietary and it can no longer be delivered with the sane software.

How look exactly your /etc/sane.d/epson.conf file?

You could always try Iscan. Its a small program from Epson that seems to work quite well with their scanners (at least my old 1650 photo anyways). There is a SlackBuild for it at SBo, although the current release is 2.8.0.

At date I am experiencing problems with the Epson 3490, running fc21 and fc22, both at least weekly updated.

I recognize the behaviour sketched in this tread. When I purchased the Epson 3490, Epson provided a scan program that worked excellent. Later on Epson did not maintain this program and after a few years one could not use it due to incompatibilities. However, one could load the firmware as described in this tread, and Sane did work good. After a while non reproducable problems started as described in this tread. Sometimes Sane worked flawlessly and sometimes I had to start Sane several times. On a root account it always worked, so I suspect policy kit. I did the permission for the group tric, but that did not solve these problems.

I did not experience the specific problem and solution described at the end of this tread.

Today was different. I think the firmware loaded almost completely, but than the whole thing crashes. In the same session I could not start Sane again or any other scan program. Some USB errors were reported one of them enumaretion. Surprisingly my scanner was reported as a 3590 instead of a 3490. I had to do a real cold boot (switching off mains) to return to a clean state.

The thing is that four days ago everything worked (despite the hindrances), but today it was totally different. My guess is that some package somewhere was changed or cleaned up that causes this, and I think it is somewhere in the USB corner. (both on fc21 and fc22).

I do not have myself the expertise to do debugging at a serious level, but if yum/dnf keeps a history track, than it must be a package that has been updated in some fews days prior to November 18th.

If you think it would help me and others to try to nail down the problem, please give me some instructions of what to do.

Since this is a Slackware forum, many aren't aware of the packaging system Fedora uses. It is likely there is some sort of log of what packages were replaced (in Slackware, they reside under /var/log/removed-packages, but it is probably different in other distros) but you'd need to check your distro's documentation to find out.

You would likely find better help on a Fedora subforum on trying to track down what may have changed rather than reviving an 8+ year old thread.

Iscan is a bit of a pain to build as you need iscan-data, iscan-network-nt as well as iscan itself (the version on Slackbuilds.org is very out of date). It is far easier to use the packages provided by Alienbob. Those are up to date.

EDIT) please ignore, I didn't spot that Basilicum revived a 7 year old thread!
