FYI I had a similar problem but with Ubuntu 16.04 and an Epson scanner
Precision V39, which I got
because I had the same problem with my old trusty Canon scanner that
stopped working when
I upgraded from 14 to 16 a few years ago. That problem I never solved,
but I did get the V39 working.
The Ubuntu help and/or discussion lists tell you a few of the necessary
steps.
I had to download 3 packages from the Epson web site: I don't remember
their names any more,
otherwise I'd tell you. In addition I got iscan-bundle-1.0.0.x64.deb,
iscan-gt-x770-bundle-1.0.0.x86.deb, and
imagescan-bundle-ubuntu-16.04-1.3.40.x64.deb. Probably only one of these
is needed, but I played it
safe.
At first, none of them worked: all these scanner software started fine,
but none could find the scanner.
In my case the solution was to diddle with the file that tells the
computer where the scanner is located.
For Epson, this is in /etc/sane.d/epkowa.conf. This file is mostly
comments and therefore surprisingly
helpful. For me the relevant part was
(snip)
# For any USB scanner not known to the backend (yet), you may, at your
# own peril(!!), force the backend to recognise and use it via libusb.
# You can do so by the following configuration command:
#
# usb <USB vendor ID> <USB product ID>
(snip)
which is even (uncharacteristically explicit for linux) followed by an
example:
# SEIKO EPSON's USB vendor ID is '0x04b8' (without quotes), where
the prefix 0x means 'hex'.
# The command 'lsusb' tells you these numbers: For my case, I get gives
(snip)
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 04b8:013d Seiko Epson Corp.
Bus 002 Device 005: ID 03f0:3817 Hewlett-Packard LaserJet P2015 series
(snip)
So I add to epkowa.conf the line
usb 0x04b8 0x013d
After doing this, it worked.
Now, the scanner software you use must know that it has to look at
epkowa.conf:
I don't quite follow how this works, but you should look in
/etc/sane.d/dll.d, where the
different scanner packages get their information. For example, iscan
uses epkowa:
cat /etc/sane.d/dll.d/iscan
# iscan -- enables the SANE backend(s) required
# Any changes to this file will be lost when upgrading iscan.
epkowa
In addition, it tells you why your upgrade may not have worked: when you
upgrade (iscan,
but by implication Ubuntu from 16 to 18) you may lose the reference to
epkowa.
