I have a Photosmart 5520 HP Printer. Have had no trouble replacing cartridges for nearly 3 years. Replaced the black one today, and it will not even print the alignment page. Have been through all the troubleshooting tips, but thus far, no luck.
I have cleaned the contacts on all the cartriges (the colored are empty but in place as recommended). I'm sure it is something simple that I'm missing. Any insighte are surely welcome.
