How do I change the ink cartridge on my Epson WorkForce 7840?

  1. Make sure that the printer is turned on.
  2. To start the ink replacement process, press the "Home" button, then "Settings", followed by "Maintenance", then "Ink Cartridge Replacement" and lastly press "Start".
  3. Carefully raise the printer's scanning until it stays in place. Then open the lid covering the ink cartridges.
  4. Avoid moving the printhead by hand or manually and avoid touching the cables inside the printer.
  5. Get your new CompAndSave Epson 7840 ink cartridge, shake it for about four to six times before opening from the package. 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.
  6. Insert the Epson WorkForce Pro WF-7840 ink cartridge to its respective slot. Gently push it in until it snaps into place.
  7. Close the lid cover for the ink cartridge and put the scanning unit back in place. The printer will go through the ink charging process, let this run until it's done to avoid wasting ink.

Epson WF-2860 Ink Cartridges FAQs

What ink does the Epson WF-7840 use?
Epson WorkForce Pro WF-7840 printer uses the standard yield Epson 812 black, cyan, magenta, and yellow ink cartridges. This printer is also compatible with the high yield Epson 812XL ink cartridges, which have the same color variation. High-yield Epson 812XL has more ink compared to the standard Epson 812 ink cartridges. Therefore high yield ink cartridges can print more pages compared to the standard ones. CompAndSave offers discounted Epson 812XL, which will replace the original Epson ink cartridges but at a very affordable price.
Is Epson high-capacity ink worth it?
Totally! They work the same as the standard Epson ink, but high yield or high capacity ink cartridges can print more pages. With that being said, you don't have to purchase and install a new ink as often as you do if you are using the standard ink. You can also save money from purchasing a high capacity ink cartridge as the cost of printing per page is definitely way less than the cost per page when using a standard ink.
