How to Replace Cartridge(s)

  1. Turn on your printer and open the cover. Then, wait for the ink cartridge carriage to stop in the middle.
  2. Gently push down on the latch of the cartridge you’re replacing.
  3. Unhook the latch by pulling out its bottom. Then, pull the old cartridge out of its slot.
  4. Take the new cartridge out of its package. Peel off the plastic tape covering the ink nozzle. Be careful not to touch the nozzle or the copper contacts.
  5. Slide the cartridge into the empty slot. Triangle-marked cartridges go into the left slot. Square or pentagon-marked cartridges go into the right.
  6. Push down on the latch to cover the cartridge until it snaps into place.
  7. Close your printer cover.


Frequently Asked Questions

How do you make your cartridges so affordable?

Glad you asked! We re-engineer used original ink cartridges to keep our production cost low. Not only do you enjoy a more affordable product, but you also help reduce waste by keeping these non-biodegradables away from our landfills!


What are the terms of your warranty?

We have a 100% satisfaction guarantee and one-year warranty with all our products. If for any reason you’re not happy with the cartridge you bought, send it back and we can give you a free replacement or your money back.
