Scanner detected but no permissions to access it

Post by Pangolin »

Hello.
I got a new Canon TS8200 series all-in-one printer and I installed the drivers provided by the manifacturer.
Regarding the scanner, I cannot use it with Simple Scan because it won't be detected.
If I enter in a terminal window

Code: Select all

sane-find-scanner
I get the following output (excerpt):

could not open USB device 0x8087/0x0024 at 002:002: Access denied (insufficient permissions)

# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

I went to /dev/bus/usb/003 and run ls -lash getting the following output:

0 drwxr-xr-x 2 root root 80 gen 14 11:22 .
0 drwxr-xr-x 6 root root 120 gen 14 11:19 ..
0 crw-rw-r-- 1 root root 189, 256 gen 14 11:21 001
0 crw-rw-rw- 1 root lp 189, 258 gen 14 11:24 003

so I added my user to group "lp", rebooted, but still I can't get the TS8200 scanner to work with Simple Scan.
Can you please help me?
Thanks.

The output from sane-find-scanner appears you used the verbose mode, i.e. you ran sane-find-scanner -v to get those access denied responses.

It looks like the scanner is correctly detected.

Did you run scanimage -L from Terminal and what was the output?

I looked at the Canon site for the driver and found scangearmp2-3.70-1-deb.tar.gz for download. Is that what you downloaded and installed?

Edit:

I cross-checked the PIXMA TS8000 series at the Sane project devices page. Looks like it isn't tested.

http://www.sane-project.org/sane-mfgs.html

Try installing XSANE and see if that app detects the scanner.

scanimage -L outputs the following message:

No scanners were identified. If you were expecting something different, 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).

I installed the 64bit driver that was inside the scangearmp2-3.70-1-deb.tar.gz archive provided by Canon website (there is also a 32bit package inside the tar.gz archive).
Xsane is not working either. I get the message "No device available"

If I use Canon's scangearmp2 tool, the scanner works but this tool is really too basic even for simpler tasks like... scanning a 2-page document!

The install.sh script looks like it does more than install the .deb packages. I'd run the script with sudo.

Not an ACL in sight. You appear to have a broken system. Please see:

https://wiki.debian.org/Scanner

Not much point in carrying on until this is fixed. Also, the permissions should be crw-rw-r--

Tried with sudo but nothing changed :(

Which version of Mint are you running? If it's 19.1, you need to check release notes page for the "Scanner not detected" problem and link to the bug report. Not sure it applies, but worth checking.
