Ghosting only on blacks, colors are okay

My Canon Pixma MX922 has a print ghosting problem only on the two black inks. Colors look good. Canon recommends cleaning the encoder/timing strip with IPA. I have done this multiple times with no performance change. Any ideas what the cause could be? Would a bad print head do this? Do I need to disassemble the printer to access and clean the encoder/timing read sensor?

Hi @damon10 ,

Just curious if it does this when printing or scanning using the printer control panel or from a computer or both?

@damon10 yes, a partially clogged print head could be the issue. Check on here how to clean it

I did throughly clean the print head. It did not fix the issue. I can try that again. It just wastes ink that has flowed from the ink cartridges into the reservoir of the print head. A few other people posted this same issue on Canon’s support sight. Canon’s response was clean the timing strip, which didn’t fit it for us.
