I had the same problem with hp psc 1350 all-in-one. Number of the cartridge 56, 57. I tried to get some ideas in the local hp technical support - no help. So I opened the whole think, cleaned the contacts on the cartridge and on the trolley, Then I pressed the smaller tape you could see on the left side ( which is responsible for passing of the data ) to make sure that there is no problems with contact. After this procedure from some reason the amber light stoped flushing.
And one more point if you press the first and second buton on the left side you get no 1 on the display and both amber diode start flushing. Then you can open the door like you would replacing the cartridge and then close them again.
Hope that this would be of some help.

The 'check print cartridge' light keeps flashing on my HP printer, so I replaced the cartridges and everything else i could think of such as restart my computer, temporarily disconnect the printer, etc. the light continued to flash. I also tried resintalling the printer software. Any ideas??
To use the photo print cartridge, remove the black print cartridge and insert the photo print cartridge in its place.

After installing or replacing a print cartridge, the HP PSC will automatically print a cartridge alignment page.
