Question about HP Photosmart C7250 All-In-One Thermal Printer
Each print, I'm prompted to replace the black ink cartridge on screen. Upon removal from the printer (shaking), its full-even the replacement is a new HP one. The onscreen display doesnt reflect a low black ink cartridge, however when printing, the exclamation is lit and I'm tasked with pushing the 'OK' button. I have restarted disconnecting everything a few times. Is there a print test page, calibrate, or auto cleaner to clear/test the ink? Anyone else having this problem?

HP support decided it could not be repaired on line, agreed to replace it but found it was a few days out of waranty...so it is dead in the water. Probably not cost effective to repair it.

Either the print head for black is faulty, or the wiring to the black print head on carriage are broken. Try also cleaning the metal sensor to the black cartridge inside the ink carriage.

I have had the same problem It is the print head not the cartridge If your printer is still under warranty have the printhead(s) replaced if not Open the unit where the print heads are and hold the OK button for 5 seconds. The Print head carriage will move to the left
Carefully remove the KY (Black & Yellow) Print head with a cotton swab and alcohol clean the contacts and replace the printhead. If this does not work remove the printhead and then with a spray bottle spray the nozzle area on the bottom (DO NOT TOUCH THE NOZZLES AS THEY WILL BE DESTROYED) HP techs have told me this will void any warranty so act accordingly I use a printhead cleaning solution available from most any online ink supplier
Replace the printhead after it has dried out (less than a minute). The printer will then go through an alignment cycle and should print I had to do this several times before the print head performed as it should
