Epson RX620 Scanner ceazed working [hardware issue]

[orange_juice]

Hallo, although I can print with my epson stylus photo rx620, I am unable to scan!

I used to enter Gimp and scan my photos using "Acquire -> Xsane: Device Dialog"

Now the menu includes the old "Acquire -> Xsane: Device Dialog" and a new one "Xsane libusb:001:004"

If I choose "Acquire -> Xsane: Device Dialog" I get "No devices available"
Choosing "Xsane epson:libusb:001:004" I get "Failed to open device epson:libusb:001:004 invalid argument.

From command line as root:

Code: Select all

lsusb | grep Epson
Bus 001 Device 003: ID 04b8:0811 Seiko Epson Corp. Stylus Photo RX620 all-in-one

Code: Select all

check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Bump! Nobody ... !

I'm going to assume you're using udev.

First make sure that the device is in /etc/udev/rules.d/70-libsane.rules

Code: Select all

grep 04b8 /etc/udev/rules.d/70-libsane.rules | grep 0811

If it is, it should be showing up in /dev/bus/usb. Make sure the group is scanner.

Code: Select all

ls -l /dev/bus/usb/001/003

If it is, you can use that link instead of the /proc link. However, this will change when your usb subsystem changes. So you should probably think about putting a symlink into the udev rule.

Open up /etc/udev/rules.d/70-libsane.rules with your favorite editor (as root, of course).
Find the line for your scanner, which you grepped earlier.
Add the symlink on the end.

Code: Select all

ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0811", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes", SYMLINK+="RX620"

This will make a /dev/RX620 node that you can always link to, no matter where on the usb chain it ends up.

Of course, after writing the rule you'll need to let the udev subsystem know there's a new one.

Code: Select all

udevadm trigger

Hope that helps.

Thank you for your answer!

I apologize for the delay.

Add the symlink on the end.

Code: Select all

ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0811", MODE="0664", GROUP="scanner", ENV{libsane_matched}="yes", SYMLINK+="RX620"

I added the symlink according to the guidelines provided, and the directory /dev/RX620 is created. However, I still cannot access the scanner.
XSane front end gives the same results as my first post.

If I choose "Acquire -> Xsane: Device Dialog" I get "No devices available"
Choosing "Xsane epson:libusb:001:004" I get "Failed to open device epson:libusb:001:004 invalid argument.

Furthermore:

scanimage: open of device hp:/dev/RX620 failed: Invalid argument

Code: Select all

Seems that I found my way out ... somehow ...

Code: Select all

scanimage -L
device `epson:libusb:002:002' is a Epson PM-A870 flatbed scanner

And then, I used the command:

Code: Select all

scanimage --device-name epson:libusb:002:002 --resolution 300 --format tiff --mode color > image.tiff

OK ... Nice!

However, Xsane still insists that there are no devices available.

Hallo, I finally found that my issue owns its existence to a hardware failure, I just acquired a new printer and I am about to buy a new scanner.
