The Meaning of Pen Failure
Older models of HP printers referred to ink cartridges as "pens." Pen failure simply means that there is something wrong with the ink cartridge, most often having to do with a bad connection between the printer and the contacts on the cartridge.
Remove and Inspect the Ink Cartridges
Remove all ink cartridges from the printer, turn the printer off and unplug it. Visually inspect the ink cartridges for damage. If the cartridges are new, make sure all the protective tape has been removed. Finally, make sure you have the correct ink cartridge for your printer.
Clean and Reinstall the Cartridges
Using a dry, clean, lint-free material, gently wipe the copper contacts on the ink cartridge. Be careful to avoid the print nozzle. Plug your printer back in and reinstall the cartridges. Make sure that they are installed in the correct slots and that they snap firmly into place. If the problem persists, contact HP technical support.
