I have an HP 4620 printer.
My black ink cartridge was running low on ink so I inserted a new cartridge. Now the printer does not print black ink at all. Just blank pages with absolutely no traces of black ink. The black ink level shows full.
I tried to:
Clean the printheads (twice)
Align the printheads (twice)
Ran the print and scan doctor (twice)
Inserting the old black ink cartridge
Buying a new ink cartridge.
It just seems odd that the printer was working fine and all I did was insert a new ink cartridge. All the other colors print fine but nothing for black ink.
Any suggestions?
Thanks in advance.
