I'm using a Pixma Pro 100 purchased in December 2020 with a 2010 MacBook pro. Mainly print from Silhouette Studio and Photoshop with genuine Canon ink. I typically print at least a few times a week.
The issue:
Replaced the empty black cartridge last week, printed a few pages fine. Go to print more today and the black was faded. On nozzle check, the black doesn't show up at all. I've tried a variety of different print settings, and sometimes it will print grey (assuming it's using the grey cartridges) or just the outline of the black object.
Things I've tried:
- Many cleanings
- Many test pages
- 3 Deep cleanings
- Cleaning the print head (focus on the black (70% IPA); then the whole bottom in a solution of warm distilled water and a bit of Windex for a few minutes, again trying to clear out the black)
I'm including some photos of the cartridge, printhead, and inside the printer. The ink on the left foam has been there are long as I can remember, there's a smaller patch to the right of the print head that might be new, not sure. I don't recall looking to the far right ever, so I can't tell if the black ink splattered everywhere is new or not.
I don't understand what could have changed in less than a week or why it's only affecting the one color, but I'd greatly appreciate any help! Let me know if you need any more information or want me to try anything. Thank you!
