When planning for a replacement, you can either choose originals or genuine third-party refills such as the CIS. If at all you have concluded that you are going to use a CIS, then you can make use of the following guidelines.

Get Rid of the Old Cartridge First

Without removing the existing one, there is no way you will be able to install a new CIS for your printer.

  • First, switch on your printer
  • And then, make sure in the paper tray it has a paper
  • There is a cartridge access door
  • This is available on the front side
  • Open it to access the cartridges
  • Once open, you must wait for the auto-calibration to complete
  • After which, you can remove whichever cartridge is empty

When you are planning to do a refill, you must handle your old cartridges very carefully. Try to tape the copper contacts before opting for a refill. This is because, when these contacts face any damage, it is irreversible. Meaning, you will not be able to re-use the cartridge again.
