For more information, see Set the date and time. Any faxes stored in memory are also erased. 3 Lift one of the latches to the open position, and then remove the print cartridge. Note Do not remove both print cartridges at the same time. Remove and clean each print cartridge one at a time. Do not leave a print cartridge outside the HP all-in-one for more than 30 minutes. 4 Inspect the print cartridge contacts for ink and debris buildup. 5 Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze any excess water from it. 6 Hold the print cartridge by its sides. 7 Clean only the copper-colored contacts.
