Hello everyone,,
I have a 3 year old MX922. Recently some of the text has been blurry. I did as print nozzle check pattern and the PGBK section comes out blurry in the middle, as though it is printing the grid and a shadow. All other color sections are fine until the Ver 2.020 on the bottom which is blurry again.
I tried
1) Clean
2) Deep Clean
3) Auto Align (did not try manual align)
4) Changed all cartridges
5) soaked / cleaned print head in ammonia, distilled water and alcohol
6) Cleaned thin transparent plastic strip in the back with q-tip and neutral detergent
Nothing fixes this.
Then I tried printing out an excel spreadsheet with lots of random numbers. I tried changing different rows colors from light blue to dark blue to black.
Only the pure black rows printed fuxxy. The dark dark navy black rows print fine.
Can I assume 1) that the two metallic squares are print heads for a) color (including BK) and b) PGBK and that the PGBK secvtion of the print head having a software head alignment problem which causes it to move out of allignment every 100 or so "dots" or printer increments? Is there anyway to fix this?

Greetings.
Some of the chemicals you are using might be a little harsh.
I'd stick with alcohol and distilled water.
What happens if you change the print quality, but leave the paper type as plain?
If the behavior persists, I believe you will need to replace the print head.
