How to install HP 3820 ink cartridges?

  1. Turn on your printer. Open the top cover.
  2. The ink cartridge's carriage will automatically move, so make sure to wait for it to completely stop moving before you proceed.
  3. Raise the cradle latch and remove the used cartridge.
  4. Get your new CompAndSave HP DeskJet 3820 ink cartridge. Open it over a sink or garbage can to avoid any mess in case it leaks, as sometimes, factories tend to overfill the ink cartridges.

  5. Push the new HP DeskJet 3820 printer cartridge firmly into the cradle.
  6. Lock the cradle latch and close the top cover.
