Photosmart D7160 - No lights - Won't turn on.

Cartridge Problem replaced it.

replace the print head unit not the cartridge.

Calibrate the printer.

Try using the HP Print Diagnostic Utility in Windows

remove the ink cartridge and print head and then do a power drain. after that insert the print head and ink cartridge.. if it still shows the 0xc. error try by replacing the print head .. first

Turn off the machine using the power button, unplug the power cord from the back of the machine, remove the ink cartridges, wait 2 min, press the power button to turn on the machine, wait until the printer prompts that the ink cartridges are missing, then reinstall the ink cartridges. If this doesn't fix the problem you may have to re-prime ink through the system. There is a good explanation of how to do this at http://www.ccl-la.com/blog/index.php/hp-photosmart-ink-system-failure-1/.

,The cartridges should have been supplied with the printer. If you didn't get them then return the printer for exchange.

I junked it!

Please send me resetting code

replace the carrage unit in the printer
