Canon MF113w White Streaks

[charlie562]

My Canon #MF113w started leaving teardrop-shaped white streaks when printing (test printing job attached). I replaced the toner cartridge and the streaks remain in the exact same location. I also attempted to clean the fixing assembly using the self-cleaning capabilities of the printer: https://oip.manual.canon/USRMA-3142-zz-SS-enGB/contents/SS113_maintenance_0240.html

I do not use the printer frequently so I have an issue believe it could be an issue with the drum cartridge. When I go to Status Monitoring, both the drum cartridge and the toner cartridge show 100%.

Hello,

If you have already tried cleaning the fixing assembly several times, it looks like there is something wrong with the hardware or the drum cartridge. In this situation, I would suggest trying another drum cartridge to see if it resolves the issue. if it does not, I suggest contacting support over the phone at 1-800-652-2666 or logging into your MyCanon account to check your service options.

As a former copy shop employee, that looks like a drum issue. I would ignore what the printer claims (that the drum is at 100%) and replace the drum.
