I am having a number of problems scanning to my Epson DX4400 mfp on Arch.

I have got the printing working, more or less, then I tried to implement scanning and installed the following packages from AUR:

iscan 2.28.1-2
iscan-data 1.14.0-1
iscan-plugin-cx4400 2.1.3-1
sane

Now if I enter:

$ sane-find-scanner

I get

found USB scanner (vendor=0x04b8 [Language Error], product=0x083f [Language Error]) at libusb:012:004

So it finds the scanner but reports a [Language Error], and I do not know what that means.

If someone could put me back on the right track I would be grateful

I did some googling, and found this link that may be of some help.

It seems the 'Language Error' can be ignored.

Hope this helps.

Thanks for the quick reply.

Although the scanner is found, scanimage -L returns no scanner found, so I assumed thatb the problem was the Language Error.

I will read though the thread that you found and report back [S]if[/S] when I find the fix.

Well I have made some changes, here are my notes:

Make sure 'epkowa' is an uncommented line in /etc/sane.d/dll.conf

Add this line to epkowa.conf in /etc/sane.d

interpreter usb 0x04b8 0x083f /usr/lib/iscan/libesint7E

Uncomment this line in 99-iscan.rules

# For Linux >= 2.6.22 without CONFIG_USB_DEVICE_CLASS=y
# If the following rule does not exist on your system yet, uncomment it
ENV{DEVTYPE}=="usb_device", MODE="0664", OWNER="root", GROUP="root"

not too sure about the last one yet, but at least I get some sort of response from scanimage:

$ scanimage -L
device `epkowa:interpreter:012:010' is a Epson (unknown model) flatbed scanner
# scanimage -L
device `epkowa:interpreter:012:010' is a Epson (unknown model) flatbed scanner
$ scanimage -T
scanimage: open of device epkowa:interpreter:012:010 failed: Invalid argument

I don't like the "unknown model" or the "Invalid argument" in the responses. Most googling points to permission problems, but the same occurs if I execute as root. I have attached a strace file from the scanimage -T above, just in case anyone can give me another nudge in the right direction.

For some reason I was missing a file in /usr/var/lib/iscan. The file "interpreter" should have been created and read:

interpreter usb 0x04b8 0x083f /usr/lib64/iscan/libesint7E

The details vary depending on the printer model.

When I reinstalled everything from scratch and undid all my amendments, all I needed to do was add the above file and it worked.
