PIXMA MX922 PGBK black ink printing double

garygulbransen — Sat, 29 Oct 2022 15:46:53 GMT

Win 11 wi-fi, no errors, print head removed and cleaned, replaced cartridges, etc etc and as I said my printout looks exactly like API posted above. Wavy lines through the middle of the black grid. The workaround suggested by someone is to print your documents in, in my case Dark Lime...evidently that eliminates the printer using the large black cartridge (labeled PGBK) and solves the problem. I did not clean the timing tape.

Hi garygulbransen,

Cleaning the encoder/timing strip will resolve this issue.

To clean the encoder/timing strip, please follow the steps outlined in the following Knowledgebase Article available from our web site:

Any other suggestions? My nozzle check pattern is exactly the same only for the PGBK. I have cleaned the timing strip twice and do not see any smudges or dirt on the strip. I have cleaned the printheads by hand, done numerous cleaning/deep cleaning cycles. No change in the pattern. Printing anything in black ink has either smudges every other line of text.

I have the same issue and attempting to clean the encoder strip multiple times has had no effect.

Causes of Double Printing in PIXMA MX922

The PIXMA MX922 may experience double printing, particularly with the PGBK (Pigment Black) ink, due to several common issues:

Print Head Alignment Issues

Misalignment of the print head can lead to overlapping characters.
Ensuring the print head is properly seated in the carriage is crucial.

Dirty Components

A dirty timing strip can affect print quality. Cleaning this strip may resolve the issue.
Regular maintenance, including cleaning the print head, is recommended.

Troubleshooting Steps

To address double printing, follow these steps:

Clean the Timing Strip:
- Use a soft cloth soaked in alcohol or window cleaner to clean both sides of the timing strip.
Check Print Head Alignment:
- Run a print head alignment test to ensure proper positioning.
- https://support.usa.canon.com/kb/s/article/ART168504
Inspect the Print Head:
- Make sure the print head is snugly seated and that all electrical contacts are clean.
Perform Deep Cleaning:
- Run multiple deep cleaning cycles to clear any clogs in the print hea

Thanks, DerrickL for the response. I've done print head alignment, both automatic and manual with little to no effect. I've not tried to clean the back side of the timing strip and not sure how to even do that. I don't see any value in running more print head cleaning cycles. I am confused about the timing strip. Why is only black impacted? I can print text clearly in any color except black. I can print photos very well. I've had the print head out of the printer a couple of times. The performance is unchanged. Colors fine, black blurry or double printing.

Print a nozzle check, if the black is not correct, I suspect that the black print head needs to be replaced.

Performing a Nozzle Check on the Canon MX922

To check the functionality of the print head on your Canon MX922, follow these steps:

Steps to Perform a Nozzle Check

Access the Setup Menu
- Turn on your Canon MX922 printer.
- Press the "Setup" button on the printer panel.
Navigate to Maintenance
- Use the arrow keys to scroll through the menu options.
- Select "Maintenance" from the list.
Select Nozzle Check
- Choose "Nozzle Check" from the maintenance options.
- The printer will print a test pattern.

Understanding the Nozzle Check Pattern

The printed pattern will help you identify if any nozzles are clogged or if the print head is functioning properly.
Look for any gaps or irregularities in the printed lines, which may indicate issues with the print head.

Thanks, DerrickL for the feedback. My nozzle print check looks just like the example referred to at the top of this thread. Is the black print head replaceable or does the whole print head need to be replaced. Thx again.

The Nozzle check should not look like the image I have added. If the black does not look like a very legible grid pattern, I still think that verifies the black ink part of the head is not working correctly. You have aligned it and deep cleaned it and if the grid is not correct then I still thing the printhead has a serious issue. The MX922 only had one print head, prints both in color and black. The trouble is finding a Canon one for sale as opposed to a third party. This is the best I could find, you might check the reviews, but before that, could you post the nozzle check for us to view? It would be good to have another member here verify if possible that this is a printhead issue.

Thanks DerrickL. I also saw multiple offerings on Amazon for generic replacement and am contemplating whether or not to spring for one. My MX922 is a backup of sorts, so it's not critical that I can print good black text on it. I can still print good photos (at least last time I checked after the blurring and double printing began) and the scanner works fine.
