Black ink won't print, but color does

[Guitarman920]

I have the 7001 and the black ink wont print even though the reservoir is full.  Additionally, none of the reservoir lights are on that show ink levels.  Color is printing fine!

@Guitarman920, Welcome to the HP Support Community! I’m here to help.

I see that the printer is not printing in black. Kindly perform the steps mentioned in this document - Color or black ink not printing, other print quality issues

Clean the printheads and print a test page as shown.

Try making a standalone copy in black from the flatbed glass and check if that works. By this, we can conclude if this is a hardware or a driver issue.
