(you can get the three .deb files from the epson or possible avasys.jp website)
19 apt-get install xsltproc
20 dpkg -i iscan-data_1.13.0-1_all.deb
21 dpkg -i iscan_2.28.1-3.ltdl7_i386.deb
22 dpkg -i iscan-network-nt_1.1.0-2_i386.deb
At that point the SX425W will scan nicely from simple-scan, but the older perfection 2480 still doesn't work, even though simple-scan lists it as an EPSON EPSON, so it obviously knows something about it.
Next I tried:
sudo apt-get install xsane sane libsane-extras
That didn't help but installed a much more complicated scanner app called xsane.
Xsane claims it can do OCR, but won't actually unless you also install
sudo apt-get install gocr
Here are some instructions for getting the 2480 working:
They amount to editing:
so that the firmware line reads:
And then putting the esfw41.bin file that you can download from there in the right place and
getting the permissions right so that any user can read it.
sudo mkdir -p /usr/share/sane/snapscan
sudo cp esfw41.bin /usr/share/sane/snapscan/esfw41.bin
sudo chmod 444 /usr/share/sane/snapscan/esfw41.bin
Having done this I seem to have disabled the other one though. sigh..
