Canon mf237w, scanner not recognized

[deano_ferrari]

Hi,

I have the same issue with MF445dw laser printer/scanner. Sometimes the printer is recognized but never the scanner even with firewall in OFF. When the printer is recognized, it works fine, but it is lost at every reboot and not a way to recognize it again. Yes, I checked the firewall, and it is OFF. The only form to use the scanner is to configure it by hand with its IP. I tried others distros (fedora & Ubuntu) and they recognized the printer and the scanner without any manual IP setting. Is it something that is missing in my opensuse to detect the network devices automatically?

thanks,

I don't own such hardware, so not clear about what fails without some wireshark analysis. Ultimately the sane driver is responsible for the discovery, and I think configuring the pixma.conf is a reasonable workaround. BTW, many modern network scanner devices support the use of sane-airscan, so that may be worth trying too.

man sane-airscan

*However not sure which version of SANE is required to provide the relevant backend. I'm running openSUSE Leap 15.3 where it is not yet available.

I can confirm that sane-airscan solved the issue to detect the scanner. Now my scanner is detected without manual IP setting on Tumbleweed. The problem detecting the printer still persist. Any more suggestions?

It should also be capable of driverless printing.

Run the following commands and report back with the output…

driverless

sudo lpinfo -v
