Hey! I have recently changed the black ink cartridge, but it is not printing in black - only grey!
I have done the following to solve the problem:
1. The new cartridge is HP original
2. Print level shows full black cartridge
3. The printheads are cleaned using Tools
4. Installed the HP Print&Scan Doctor - to faults found - all marks are green
Is there anything else I can do?
