If you regularly print documents for your business, you’ll need to perform frequent maintenance to keep your printouts sharp and clear. Over time, dried ink and dust can clog the ink nozzles and cause streaks or blank spaces on the paper. HP Deskjet printers have a built-in process that cleans dried ink from inside the cartridges, which may eliminate missing lines or dots on your printouts. If you notice ink streaks after printing, you’ll need to manually clean the cartridges to remove any external debris.
1. Turn on the HP Deskjet printer and lift the cover. When the ink cartridges move to the center of the printer, unplug the power cord and lift the cartridges out of the printer.
2. Set the ink cartridges wide side down on a piece of paper. Dampen cotton swabs with water and squeeze out any excess water. Clean the edges around the nozzle plates on the bottom of the ink cartridges. Do not touch the nozzle plates or copper contacts with the cotton swabs.
3. Clean the ink cartridge cradle inside the printer with clean, damp cotton swabs. Allow the ink cartridges and cradle to dry before replacing the cartridges. Close the printer cover and plug in the power cord.
4. Print a test page to ensure that the cartridges were reinstalled properly.
