HP DeskJet 3810 Ink Replacement Guide

  1. Turn on the printer and wait for the machine to get ready.
  2. Open the top cover or cartridge access door. Wait until the internal carriage stops moving and rests in the center.
  3. Remove the old cartridge by pressing down gently or pushing in on the tab/front of the cartridge to release it, then pull it straight out of its slot.
  4. Unpack the new CompAndSave HP 3810 ink cartridge and completely remove any orange pull-tabs, plastic wrap, or protective orange caps.
  5. Avoid touching the copper-colored electrical contacts and the ink nozzles to prevent clogs or connection failures.
  6. Insert the new cartridge firmly into its matching color-coded slot until it clicks or snaps securely into place.
  7. Close the cartridge access door and top cover.

HP DeskJet 3810 Ink Cartridge FAQs

Can I use Epson ink in HP printer?

The short answer is no. HP and Epson ink cartridges have different sizes, fittings, contacts, and printer compatibility. Installing an Epson ink cartridge to an HP printer or vice versa will not be recognized by the printer and might cause some damage. So, to avoid damaging your printer, make sure to only install the ink cartridge intended for your printer.

Is it OK to use non-HP cartridges in my printer?

The answer is yes. It is fine to use non-HP ink cartridges for your printer. CompAndSave's ink cartridges are designed to meet or exceed the OEM specifications and guarantee that the quality is the same way as the original ones at a lower price. Also, our products are covered with a 1-year warranty. Please note that using third-party ink cartridges will not void your printer warranty.

    Item received was exactly as ordered. Packaged well and arrived in good shape. All colors performed well, and left no streaks, etc., on the paper. Quite pleased with the cartridges and performance considering that the HP952c has been discontinued for quite some time. Parts are extremely scarce and usually are supplied by third-parties.

    A great deal. Far better than ordering on eBay. Far better than trying to get it from HP that no longer supports it and was always a bad deal.
