    • Make sure the power supply/interface cables are disconnected before proceeding!

    • Open the print head/ribbon cartridge cover.

    • Remove the two Phillips screws securing the two grounding brackets which hold the cutter unit in place.

    • Set the metal brackets aside.

    • Do not pull on them forcibly – you risk tearing the grounding wires.

    • Remove the cutter, being careful not to tear/pinch the cable coming from it.

    • Disconnect the cable connecting the cutter to the printer.

    • The blade will be accessible after separating the two halves.

    • The blade is sharp! Be careful not to injure yourself.

    • Make sure to note the position the blade is installed in.

    • The toothed edge should be facing the opening for the paper, with the longer of the three notches on the right (assuming the frame is oriented as pictured).

    • Make sure to route the wires coming from the cutter assembly through the groove in the left hinge of the print head cover when reinstalling the assembly into the printer.
