We have several of these B111a All in one printers. This is the second one that I've had this issue with.
New Genuine HP ink cartridges always used. Printer is just a year old.
Black ink fades like it may be running out of ink. Insert new ink cartridge and prints just a few pages before the same issue arises.
I've used the printer scan doctor software and no improvement.
Printer is used everyday so no chance of print head being dried out or clogged.
Anyone know the solution?
