HP Business Inkjet 2800 Printer Series - Cleaning the Printhead Contacts Manually

Information

This document describes how to clean the printhead contacts manually in the case of a HP Business Inkjet 2800 printer.

Details

  caution:
Clean the printhead contacts only after you have attempted to clean the printheads automatically. Printhead contacts contain sensitive electronic components that can be damaged easily.
Use the following steps to clean the printheads automatically from the printer:
  1. Press Select button on the control panel.
  2. Press Up Arrow button until MAINTENANCE is highlighted, and then press Select button.
  3. Ensure that PRINT QUALITY is highlighted, and then press Select button.
  4. Press Up Arrow button until the option to clean printheads is highlighted, and then press Select button.
To clean the printheads contacts manually, refer to the following steps:
  1. Ensure the printer is plugged in and turned on.
  2. Lift the ink cartridge cover and the printhead cover.
  3. Wait two or three seconds, and then unplug the printer power cord.
  4. Lift to open the printhead latch.
  5. Lift the handle of a printhead, and use it to pull the printhead out of its slot.
  6. Carefully remove any ink from the contact pads on the printhead using a dry cotton swab or a soft, dry, lint-free cloth that will not come apart or leave fibers behind.
      caution:
    Only wipe the contact pads. Wiping the nozzles (located on the underside of the printhead) can cause severe damage to the printhead.
  7. Insert the printhead into its color-coded slot. Press down firmly on the printhead to ensure a proper contact.
      caution:
    Avoid using drinking water or alcohol, which could damage the printheads.
  8. After cleaning, place the printhead on a sheet of paper or a paper towel.
  9. Clean the contact points in the printhead slot inside the printer with a dampened cotton swab. Before re-inserting the printheads, make sure that all the electrical contacts have had at least five minutes to dry.
  10. Plug in the power cord, and turn on the printer. The control panel should still indicate that a printhead is missing.
  11. If you are replacing a printhead, remove the new printhead from its package, and then remove the protective tape.
  12. Insert the printhead into its color-coded slot. Press down firmly on the printhead to ensure a proper contact.
  13. Close the printhead latch. Ensure that it is in the lock position.
  14. Where necessary, repeat the previous steps for the remaining printheads.
