prompting you to check a print cartridge after you already have cleaned or aligned the
print cartridges, or if the Check Print Cartridge light is blinking.
Before cleaning the print cartridge contacts, remove the print cartridge and verify that
nothing is covering the print cartridge contacts, then reinstall the print cartridge. If you
continue to get messages to check the print cartridges, clean the print cartridge contacts.
