The HP Deskjet 1280 is a desktop printer for both home and office. If you own one of these common printers, take the time to develop some troubleshooting and repair skills, since professional service can be prohibitively expensive for an entry-level printer like the HP 1280. The more work you can do on your own, the more money you can save and the faster you can get your printer back in service.
Press the "Power" button to turn the Deskjet 1280 on. Lift the top cover, and wait for the print cartridge carrier to stop moving.
Tilt the print cartridge forward, and lift it carefully out of the printer. Set the print cartridges aside.
Swab the print cartridge carrier with a cotton swab dipped in warm water. Continue to clean the cartridge carrier until the swab comes back clean. Over time, paper dust and ink residue can collect under the print cartridges, which can cause problems with print quality.
Vacuum all accessible areas of the HP 1280 to remove any remaining dust and debris. Use a small crevice tool attached to a handheld vacuum cleaner, or a small vacuum cleaner like those used to clean the interior of computers.
Turn the print cartridges over, and swab the metal connectors on the bottoms with a cotton swab dipped in warm water. Continue to clean the cartridges until no more ink residue comes off. Set those print cartridges, metal side down, on a paper towel and let them sit for 10 to 15 minutes, then check for leaks. Replace the ink cartridges if they are leaking.
Remove the paper from the paper tray, and feel inside the printer until you find the feed rollers. Feel for any labels or torn paper wrapped around the rollers. If you feel a label or anything else stuck to the roller, soak a cloth in isopropyl alcohol and hold it firmly against the roller while you turn it. Continue to move the roller until the label peels away.
