My printer was down for three weeks because the hp printer always said defective or missing printhead i tried everything to make it work but it did not work

The printer gave no errors after installation of the print heads and during the alignment process

I wasnt sure how to replace the print head but i found a video on youtube

This did the job though i forgot to remove the blue tape at first and it kept telling me the printhead was missing or broken

I received a message from the printer saying non genuine hp product may harm operation of printer and void warranty

Previous print head was not working in my hp 8500a and this replacement came quite handy and easy to install

When i first put it in the printer didnt seem to do anything but i remember reading a reviewer that said to unplug and restart

I received this print head and the black and yellow printhead in the same shipment
