A:Answer Thank you for reaching out. E means there is an error with the cartridge(s). This condition occurs when at least one ink cartridge needs attention, is faulty, incorrect, missing, damaged, or incompatible. Remove and reseat both ink cartridges, clean the ink cartridge contacts (if you have handled the cartridge and perhaps touched the contacts), restart the printer, and replace one or both ink cartridges if necessary. (Insert one ink cartridge at a time to identify the problem cartridge. Make sure you are using HP ink cartridges. If the problem persists, please call HP Support to assist.
