I have Mfb44Cdw printer that is bleeding color onto Blk/Wht pages. How do I resolve this?

Hello,

The issue would usually be caused by a problem with the toner cartridge or some toner powder has spilled inside of the printer. You can try reseating the toner using the steps in the link HERE and wiping up any loose toner powder inside of the printer with a damp cloth. You can also inspect the color toner cartridges to see if any are leaking. After reseating the toner and cleaning the interior, you can try cleaning the ITB and fixing assembly.

I'm having the same issues. First the magenta cartridge was leaking during b/w printing. I changed that out when it was still at 50% and now the yellow is leaking. Do all Canon cartridges leak? This is an expensive situation if I have to discard another cartridge that is still at 50%.

Hello,

It is not normal for the cartridges to leak that often. In this situation, I suggest contacting support directly. They can check the hardware and the toner cartridges to see what is going on. You can contact support directly at 1-800-652-2666.
