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