Hi all, hoping someone here has seen this before because Canon support is stumped.
My Pro 200 is producing a small black/gray dots in roughly the same position on every print — left of center, top surface of the paper. It looks like a pen touching paper briefly, pinhead size, roughly circular but not perfectly so. Appears on all paper types, including plain cardstock and printer
Here's everything I've already tried:
- Multiple bottom plate cleaning cycles
- Paper feed roller cleaning
- Manual cleaning of platen protrusions with isopropyl alcohol (found significant ink and fiber buildup, removed it)
- Cleaned the cartridge rail
- Removed and wiped down the print head assembly exterior with a dry paper towel (removed a lot of ink)
- Inspected and wiped the ink connection ring on the black cartridge
- Enabled Reduce Abrasion setting
- Ran a 100+ print job to see if it would work itself out — dots unchanged throughout
The dots are on the top surface of the paper, not the underside, which rules out the platen protrusions. Position is consistent — left of center — which makes me think it's a fixed contact point rather than random dripping. New black cartridge arriving tomorrow which I'll try next.
Has anyone seen this and found a fix? Really don't want to replace the printer over something this small.
