Question about Canon PIXMA MP780 All-In-One InkJet Printer
I replace print head with new one.
I replace all ink cartridges with new OEM.
Black 3ek cartridge is not printing black.
I have made all checks and runs of maintenance programs.
Printer not able to make auto print head alignment.
I tried a second brand new print head and other new Black 3ek cartridge.
The same result. Composite colors working, pure black prints do not.
I have to admit that before that I intensively used refilled cartridges.
I had the same problem before with 3e black ink. It simply does not print too, so what I did if i get to print black and white i will set the characters into dark gray! it looks like draft printing but the things is it can be printed.. I tried to do every instructions available but to fail. I almost dump it till I decided to set it aside for a while. After a week I tried using it again, and it functions well. I guess the printer just want to say, "HEY BUDDY, GIVE ME A LITTLE BREAK!"
