I have an ImageClass mf236n that was working fine up until 2 or 3 days ago (around 8/17/23). It stopped scanning and printing completely, spitting out an error: "Cannot communicate with the device. The cable may be disconnected, or the device may be turned off. Check the device status and try again. Scanner driver will be terminated. Code: 155,0,0".
In troubleshooting, I reinstalled the latest drivers and utility software (winmfscanutilityv12101) from the Canon web site with no success. I replaced the USB cable twice but still the same behavior. I then installed an older version of the software (winmfscanutilityv12004) and voila, the scanning functionality worked even with the old cable. However, I found out later that the print functionality no longer works. The printer is unresponsive to print commands, and the print queue doesn't show anything. I've reinstalled the latest drivers. Would appreciate any assistance.
