Question about HP PSC 750 All-In-One InkJet Printer
I have been using my printer (all-in-one) with no problems, then out of the blue I start getting the "Incorrect color printer cartridge installed" error. I have the HP 78 color cartridge installed and it's been working up until today.
I removed it then reinstalled it but cannot get the error to clear and allow me to use the print function. HELP!!
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!

It's a long shot, but I would attempt to reset the device back to defaults. If this HP has a "menu" feature, then factory defaults should be an option. Before doing that (and I know this is a dumb question), have you turned the printer off, then turned it back on after a brief rest?
Let me know if this helps and please remember to rate those who assist you :)
