Like all printers, the Hewlett-Packard 3310 All-in-One printer can break in a variety of ways. Some problems can be fixed with software or the buttons on the machine, but for others you'll need to go in manually. Luckily, the HP 3310 offers a few more disassembly options than many printers. You can open the front and back to better locate your problem. Note that anything beyond these steps (i.e., prying something apart with a screwdriver) will void the warranty and may break the printer.

Skill level:


  1. 1

    Unplug the printer. Do not plug it back in until it is fully reassembled.

  2. 2

    Remove the rear access door. You'll find this taking up the bottom half of the back of the printer. Slide the small catch left to detach.

  3. 3

    Remove the duplexer. This is the long tubelike structure right behind the door. You can just slide it out.

  4. 4

    Open the cartridge access door by sliding your hand under the front panel and lifting up.

  5. 5

    Remove the ink cartridges (five little coloured boxes and one black box, all in a row) by pressing down on each individually. This will pop them up and out.

  6. 6

    Remove the toner bar. This is a long cylinder behind the cartridges. It will come out with a little gentle wiggling.

  7. 7

    Reassemble the printer after repair. Do not plug it back in until you are finished.
