Faded print on HP Color 4600

[Printerdude]

Since printing issue is happening with two different computers, let's look at the printer itself.
Make sure economode is off.
Did you do a cold or NVRAM reset?
Did you swap the black cartridge to a color slot and a color cartridge to the black slot and print a document

To do this, go to the Diagnostics Menu and select Disable Cartridge Check. Now you can move cartridges to different slots.
Remember to exit this mode when you are done.

Try using the black cartridge only and leave the color cartridges out or use a color in the black slot and leave the rest out and
print a document.

While in PQ test mode, did you swap the black cartridge to a color slot and a color cartridge to the black slot and print a document?

to do this he has to put the printer in " disable cartridge check " or it will error out
