I have a canon pixma pro-10. I have not printed any pictures in a while and I noted that the colors were off. I printed the Nozzle check pattern and noted that PC, PBK and C had no ink. I performed 2 print head cleanings and the PC came back somewhat but with streaks and PBK and C still showed no ink.
At this point I think the next step should be is to manually clean the print head. I have found several methods : lukewarm water, water with isopropanol (rubbing alcohol) and Windex.
Water seems safest to me and would have low risk of damaging the print head, but I would appreciate opinions from any of the community.
Thank you all for your help!
