HP DeskJet 3938 Ink Cartridge Replacement Guide

  1. Make sure that the printer is turned on and load a stack of plain white paper in the paper tray.
  2. Open the output tray in front of the printer. Look for the handles inside and grip it open to access the ink cartridges.
  3. The ink cartridge's carriage will automatically move so make sure to wait for it to completely stop moving before you proceed.
  4. Gently push down the ink cartridge to release it then pull it out from the printer.
  5. Get your new CompAndSave HP 3938 ink cartridge, and open it over a sink or garbage can to avoid any messes in case it leaks as sometimes, factories tend to overfill ink cartridges.

  6. Insert the HP DeskJet 3938 printer ink cartridge into its respective slot, and gently push it in until it snaps lock into place.
  7. Close the printer cartridge access door and let it print the alignment page.

    It was really hard to get the printer ink to work. It kept printing test pages and it will not stop moving in the compartment.
