HP DeskJet 840c Ink Cartridges Replacement Guide

  1. Turn on your printer, then disconnect the power cord from the printer's back.
  2. Lift the cradle latch and open the top cover.
  3. Remove the old ink cartridge from its cradle.
  4. Get your new CompAndSave HP DeskJet 840c 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. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color along with the plastic protective case, if there is, before installing it.
  5. Insert the HP DeskJet 840c cartridge in the print cartridge cradle and press it down firmly until it is secured in place.
  6. Close the latch on the cradle. You'll hear a click when the latch is entirely closed.
  7. Connect the power cord, then close the top lid.

HP DeskJet 840C Ink Cartridges FAQs

Can you use compatible ink cartridges in HP printers?

Yes, you can use compatible, replacement or remanufactured ink cartridges for your HP printer. Compatible, replacement, or remanufactured 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. Our compatible, replacement, or remanufactured ink cartridges are also covered with a 1-year 100% satisfaction guarantee. CompAndSave offers the replacement HP 15 black ink cartridge and HP 17 tri-color ink cartridge for your HP DeskJet 840c printer at a much more affordable price.

Can I refill HP DeskJet cartridge?

Yes, you can refill genuine HP cartridges. You just need to have the right instruction and tools in order to do so. But to avoid issues, we highly suggest you replace any empty ink cartridges. CompAndSave offers a wide variety of cheap printer ink cartridges at a much lesser price without compromising its quality. Our cartridges are manufactured to meet or exceed the OEM specifications, which will save you from all the trouble of going through the process of refilling an ink cartridge. If you need a step-by-step instruction on how to refill an ink cartridge, click Ink Refill Guide, and you will be redirected to the right page.

Why is HP ink so expensive?

OEM ink and toner manufacturers claim that the high cost of toner cartridges is due to the research and development of technologies to deliver high-quality ink and toner. However, it is worth noting that there are generic cartridges that exceed OEM requirements while being less expensive than their counterparts. CompAndSave's compatible and replacement ink and toner cartridges are engineered to meet or exceed OEM standards. That is to say; you can have the same print quality and page output without spending a fortune. Please keep in mind that using generic, remanufactured, or replacement cartridges will never void the warranty on your printer.
