- 1). Leave the printer off for an hour before you change the cartridge. Laser printers become very hot internally with use. If you like, you can wear protective gloves.
- 2). Open the printer. The handle is on the front under the copier tray and the entire tray lifts up.
- 3). Flip up the security latch to the left of the current toner cartridge. The latch is gray and flips up easily. This will release the old cartridge. Grab both sides of the old cartridge and lift straight up. Dispose of the old cartridge in a sealed plastic bag away from heat or flame.
- 4). Set the new cartridge into the tray where the old one was and push down on both sides until it clicks into place. Flip the security latch down again and close the printer lid.
- 5). Turn on the printer and wait a minute as it resets the printer head and accepts the new toner cartridge. Print a test page to make sure the new cartridge works.
