How to change HP DeskJet 842C ink cartridges on printer?

  1. Turn the printer on. Then open the printer's top cover.
  2. The ink cartridge carrier will move and settle for the cartridge replacement position. Do not move or stop the print holder by touching it or forcing it to move. Allow it to settle without interruption.
  3. Raise the tab that holds the cartridge and pull the cartridge out of the machine.
  4. Get your new CompAndSave HP 842C ink cartridge. Open the cartridge over a sink or garbage can to avoid any mess in case of an ink leak, as sometimes, factories tend to overfill cartridges. Make sure to touch the black plastic part only, then remove the covering tape that is usually bright in color and the plastic protective case, if there is, before installing it.
  5. Insert the HP DeskJet 842C cartridge in the holder and lower the tab to secure it.
  6. Close the printer's cover.

HP DeskJet 842C Ink Cartridge FAQs

How do I fix incompatible HP ink cartridges?
First, make sure that the ink cartridge you are installing in your printer is the right cartridge model. To verify, check the printer's manual or check the depleted ink cartridge. In front or on the side is a label or sticker with the printer model, which is usually a combination of alphanumeric characters. If you have already verified this part, the next step is to troubleshoot by turning off the printer for 15 minutes and wipe the contacts of the ink cartridge with a nonabrasive towel or cloth with water or alcohol. For more detailed information, just click our Troubleshooting Tips.
Why is HP ink so expensive?
OEM ink and toner manufacturers claim that the high cost of these cartridges is due to the research and development of technologies to deliver high-quality ink and toners. 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 means 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. For additional information, please visit our Ink Knowledge Base.

    Excellent service and your product so far has been of the highest quality. I will stick with this company for my computer printer ink needs and probably recommend it to friends who need an ink supplier.
