How to Install HP DeskJet 3918 Ink Cartridges?

  1. Make sure that the printer is turned on.
  2. Open the printer's ink access cover. The ink cartridge's carriage will automatically move, so make sure to wait for it to completely stop moving before you proceed.
  3. Light press the ink cartridge down to release it, then pull it out from the printer.
  4. Get your new CompAndSave HP DeskJet 3918 printer ink cartridge. Open it over a sink or garbage can to avoid any messes in case it leaks as sometimes, factories tend to overfill ink cartridges. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color as well as the plastic protective case, if there is, before installing it.
  5. Insert the new ink cartridge to its respective slot and make sure that the cartridge is secured in place.
  6. Close the printer's ink access cover.

HP DeskJet 3918 Ink Cartridges FAQ

What ink does HP DeskJet use?
HP DeskJet printers use different kinds or models of ink cartridges. To know the model number of the cartridge your DeskJet printer is using, you may check the user's manual that came with your printer. You may also check the existing cartridge that is installed in your printer. In front or on the side is a label or sticker with the model number, which is usually consisted of alphanumeric characters. For example, the HP DeskJet 3918 printer uses the ink cartridge that has the model code of HP 21 for black and HP 22 for tri-color.
Can you use compatible ink cartridges in HP printers?
Yes! CompAndSave's replacement, remanufactured, or compatible ink cartridges are designed to meet or exceed the OEM specifications. This means that you can get the same print quality and the number of prints without paying as much compared to the original ink cartridges. Using these types of cartridges will not void your printer's warranty. To know more about these types of ink cartridges, click ink knowledge base and you will be redirected to the right page.
