To install the standard media cutter, you must remove the standard bezel and disconnect DC input power to the printer. See Removing the Standard Bezel.
There are no operator serviceable parts in the cutter unit. Never remove the cutter cover (bezel). Never attempt to insert objects or fingers in to the cutter mechanism.
Using unapproved tools, cotton swabs, solvents, etc. may damage or shorten the cutter’s usable life or cause the cutter to bind.
Place the cutter module and printer right side up with the top of the module even with the bottom of the top cover. Center and push the module into the front of the printer and slide it up until it stops.
Turn the printer upside down and attach the module to the printer with the two screws using the Torx wrench.
For optimal printer performance, update the printer’s firmware after installing options or immediately after the printer’s initial setup. See Updating Printer Firmware.
