Resetting the Hewlett Packard C5010A (#14) Color Ink Cartridge Estimated Ink Level
The new HP OfficeJet D Series and CP 1160 Color Ink Jet series using the #14 black ink cartridges has an estimated ink level gauge that allows the user to view the amount of ink remaining in the cartridge. This gauge must be shut off in order to refill the cartridge. It is a simple procedure that can be done in the matter of seconds.
To turn the ink level gauge off for the HP C5010A (#14) black cartridge used in the OfficeJet D Series:
1. Refill your cartridge using your Ink Jet refill kit.
2. Press the < and > (also the + and -) at the same time, then release quickly (the lcd panel must be showing the date or the procedure will not work)
3. On the keypad, press in order 7, 8, 9.
4. A message will appear asking if you want to override the ink level gauge. Press 1 for yes (You can later turn the ink gauge back on if you install a new cartridge by going through steps 2 and 3, then pressing 2 when prompted if you want to override the ink level gauge).
Your ink level gauge is now turned off and can resume printing.
