REPLACING THE PRINTER MECHANISM
Remove Old Mechanism
1. Disconnect the 10 position (white) and 12 position (red) connectors from the top of the printer
mechanism. Also disconnect the 2 position and 3 position connectors from the Printer
Controller PCB.
2. The printer mechanism is secured with 4 screws and washers. Loosen the 2 bottom screws
but do not remove them. Remove the 2 top screws and washers and then lift the defective
printer mechanism away from the Printer Mounting Bracket.
Install New Mechanism
3. Install the new printer mechanism (cable connectors upward) by slipping its 2 bottom
mounting slots behind the flat washers on the remaining 2 bottom screws and securing the 2
upper slots with the previously removed screws and washers. Be sure the wires from the 2
position and 3 position connectors are not pinched and are fed out the top of the printer
mechanism. Snug all four screws, but do not over-tighten or you may damage the secured
nuts.
4. Reconnect the 2 position and 3 position connectors to the Printer Controller PCB. Also
reconnect the 10 position (white) and 12 position (red) connector from the Printer Controller
PCB to the printer mechanism.
