I heard purge unit cleaning but know nothing about the proper procedure other than to ruin the unit due to mishandling. If a good Youtuber to give example, I will definitely give a try on this. Always appreciate your help to those in printer trouble.
Thank you for your comment, "The Hat".
If this is the case, I would ask how the 4 colors in the same group their cartridge have ink flow issue? This is hard to happen coincidentally.
I have the same story recently, but happened in group 1 (PC, M, Y, PM). I clean the printhead when this occurred, after that to get a temporary workable printing for just few days, then it happened again. From time to time, I replaced the printhead with a brand new from Canon. I hope this is not...
Wanna know if you have tried A-Sub and Koala Luster photo paper before?
How is their quality?
Heard somebody said the price and quality are both attractive.
Appreciate the comment and suggestion.
I found from web that if I can download this Canon Service Tool V5103 and run it, I can direct change my print to USA region. Is this correct?
