Have installed Xsane on Linux Mint v19 on Dell laptop. Can print fine. Is plugged directly into USB port on machine.

on executing sudo xsane and clicking on Scan, get msg box:

Error during read: Error during device I/O

Same result not using sudo to execute.

scanimage -L gets the following:

scanimage -L
device `pixma:04A9176C' is a CANON Canon PIXMA MG2400 Series multi-function peripheral

So it obviously sees and knows the device. I changed the pixma.conf file to uncomment the timeout, setting it at 5000 and verified the change took.

ps -ef | grep xsane yields:

slang@slang-Latitude-E5440:~$ ps -ef | grep xsane
root 13057 13044 0 12:33 pts/1 00:00:00 sudo xsane
root 13058 13057 1 12:33 pts/1 00:00:01 xsane
slang 13072 12564 0 12:34 pts/0 00:00:00 grep --color=auto xsane

Scanner works on Windows / HP laptop.

Thanks for any help.

Turned off scanner (for about the nth time) and it is now working, was able to scan to jpeg (and see that xsane allows scanning to numerous formats, but you have to designate one because there is apparently no default and system will say unrecognized format).
