Could have a corrupt driver.
Disconnect
the printer or at least be sure it is turned off. I'd do
both and when the CD software program asks you to connect the printer
to the USB port, do so and it should again work properly.
Hope this helps. Bud
SOURCE: HP D135 - replaced printhead - still doesn't print in that color
try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.
Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

SOURCE: HP PSC 750xi - Incorrect color printer cartridge installed error
I had this same problem and by a luck I fixed it. Not sure if the method to the madness had anything to do with it, but I'll put it down in the order that I did everything.
1. reset to factory defaults
2. pulled all cartridges out. it prompted me to put color in first, then black. message was still blinking so i took out color and put it back in again.
3. i did the partial reset by holding down cancel and left arrow while i unplugged/replugged the printer.
4. no the printer started displaying "remove and check color cartridge" (or something to that degree)
5. i took out color cartridge, cleaned the contacts with water on towel, and replaced cartridge.
6. same message still being displayed, but it allowed me to print a maintenance report. so i then cleaned cartridges and aligned cartridges through standard menu.
7. msg still being displayed, so i turned off/on printer again. this time it came back up with no message at all.
8. printer now works
hope this helps and works for ya'll too!
