Canon PIXMA MX922 prints wavy lines and ghost images.

Hi.  My Canon PIXMA MX922 prints wavy lines and ghost images.  I've ran EVERY diagnostic and I have also cleaned the clear strip inside the printer. HELP!!!  Is it just the printer's time to expire?

Hi Chris2021 and JessesGirl,

Having a smudge on the encoder/timing strip will cause the behavior that you have described. Please make sure you are cleaning the whole strip, from right to left. To clean the encoder/timing strip, please follow the steps outlined in the following Knowledgebase Article available from our web site:

I tried cleaning the timing strip several times and still get ghost lines. It only hapens with fine letter and fine lines. When I print the test patern after cleaning the fine line grid has the ghost lines only in the center the top and bottom are fine.

Patrick, 

I too have this same ghosting issue on an MX-922. Exactly like the images from Chris2021 and Barney2. It only occurs with  the PGBK and BK inks; colors look fine. I have cleaned the timing strip at least a half dozen times, front and back with 70% IPA on a Q-tip. The strip shows no signs of grease or ink smudges. So what is the next step of troubleshooting?  Is the sensor head possibly dirty? Does this require disassembly of the printer to access it? I am quite experienced with high tech equipment maintenance, but loosing patience with this Canon product. It may be replaced with a Epson shortly.

I am having this exact same problem! I've tried nozzle cleanings, head alignments, etc multiple times and nothing works. Anything printed with just the color inks and photo black comes out fine. It has to be something related to the big black ink.
