Hp printer will not detect new ink cartridge has been installed. Thought it was the cartridge, bought a new one and it still says it needs replaced.

I have had similar problem with my HP C6180. Over several months I have replaced Lt. Magenta at least 6 times. Finally I got a "Cannot Print" message after the 6th full cartridge. I tried removing/replacing cartridges, doing a hard reset, and clearing the hardware failure status (press # and *, enter code 1,2,3, scroll to 'System Configuration' press OK then scroll to 'Hardware Confifuration) - all to no avail.
I decided to remove the BIOS battery. Only do this if you're ready trash your C6180 and able to buy a new printer immediately! Remove 2 the black screws holding the left side panel in place and remove it to reveal the circuit board. Remove 5 silver screws securing the circuit board, and carefully tilt it up. On the back side, center front, is a silver 3 Volt Lithium battery; remove it. Cover the printer and let stand overnight. I did this, and when I put the battery back in and powered up the printer, error messages were gone, and it printed normally. I was lucky, but if you're prepared to take a total loss on your C6180, this might just work. My theory is that the hardware "forgot" it' error message.

Hi there !!

The printer powers up properly, but when a print job is sent, the power light flashes and an error message appears. The error message could be any of the following:

• Bidirectional communication with the printer has been lost.
• One of the ink cartridges is not found.
• Mechanism error.
• Ink cartridge is not installed correctly.

1. Open the access door (top cover) to get a clear view of the printer’s moving parts to identify anything that may be blocking or impeding free movement of the carriage. The carriage should move to the center of the printer.
2. Remove the ink cartridges from the carriage, and verify the correct cartridges are being used. The black ink cartridge should have a part number of HP 51629A. The color cartridge should have a part number of HP 51649A. If a photo cartridge is installed the part number should be C1816A.
3. Lay the ink cartridges on a piece of clean scrap paper to avoid getting ink on other items.
   NOTE: The ink cartridges should not be removed from the printer for more than 30 minutes.
4. Unplug the power cord from the printer.
5. Pick up a cartridge by the blue top. Locate the copper colored circuitry strip on the back of the ink cartridge. Clean the copper colored strip, using a clean foam-rubber swab or lint-free cloth slightly dampened with water. Use a clean dry foam-rubber swab or lint free cloth to remove the moisture from the contacts. Do not touch or wipe the nozzle plate on the bottom of the cartridge. Repeat this cleaning procedure with the other cartridge.
6. Locate the carriage contacts inside the printer. The carriage contacts are the gold colored contacts on the back wall of the ink cartridge carriage. Clean the carriage contacts, using a clean foam-rubber swab or lint-free cloth slightly dampened with water. Use a clean dry foam-rubber swab or lint free cloth to remove the moisture from the contacts. If the carriage contacts show noticeable damage, then the printer will require repair. Contact the HP Customer Support Center listed in the printer's User's Guide for information on having the printer repaired.
7. Move the ink cartridge carriage from side-to-side to ensure the carriage assembly moves freely.
8. Plug the power cord into the printer. Make sure the printer is turned on.
9. Firmly reinstall the ink cartridges, making sure they snap into place in the carriage, then close the top cover.
10. If the Resume light goes off after the top cover is closed, then run a self-test by pressing and holding the RESUME button (upper) until the power light begins to flash.
11. If the Resume light continues to flash, the problem still exists. Try replacing the ink cartridges in the printer with new ones. If the new cartridges do not fix the problem, the printer will require repair. Contact HP Customer Support Center listed in the printer's User's Guide for information on having the printer repaired.
