HP PSC 2400 and 2500 Series - Cleaning the Contacts

Gather cleaning supplies

Gather the following items to clean the cartridges and print carriage:
  • Clean distilled water. Use bottled or filtered water if distilled water is not available.
  • Clean cotton swabs or any soft, lint-free material that will not stick to the cartridges (coffee filters work well).

Clean contacts

note:
Try to clean the contacts quickly enough that the cartridges are not outside of the printer for more than 30 minutes. The ink can dry and clog the nozzles if the cartridges are outside of the printer for too long.
  1. Remove the cartridges. Click here to see how.
  2. Place the cartridges on a piece of paper with the nozzle plate facing up.
  3. Unplug the printer power cord.
  4. Lightly moisten the lint-free cleaning material with clean water.
  5. Clean the cartridge contacts. Avoid touching the nozzles. Replace the cleaning material if it gets dirty.
