HP Officejet 7110 black ink light flashing

[Tony_rainmaker]

Only 14 months old, out of warranty. Replaced printheads correctly, possibly needlessly. Installed Genuine HP black ink cartridge but alert light, power button light and black ink warning light all 3 are flashing. Tried factory reset and tried hard reset (pulling out power lead with printer switched on) neither clear the error. All 3 lights still flashing. Can anybody help ??

KInd Regards - Tony

Welcome to the HP support community.

I understand that the power and the cartridge lights are blinking,I am glad to assist you.

Follow these steps to remove and then inspect the problem cartridge.

1. Find a clean, lint-free cloth (eyeglass wipes or coffee filters work well) that you can use to clean the cartridge contacts.

2. Press the Power button to turn on the printer.

3. Open the cartridge access door. The carriage moves to the left side of the printer. Wait until the carriage is idle and silent before proceeding.

4. Push in on the front of the problem cartridge to release it, and then pull the cartridge toward you to remove it from its slot.
