6. Slide the printer assembly backwards and out of the metal frame on which the assembly is
mounted.
7. The printer ribbon cable is soldered to the bottom of the printer and attached to the CPU
board by means of a connector. The ribbon cable connector is accessible through the cavity
in the metal frame once the printer is detached.
Carefully insert a small flat blade (—) screwdriver into the cavity, to one side of the connector and
pry upwards. Then insert the screwdriver into the cavity on the other side of the connector and
pry upwards.
8. Repeat this activity several times until the connector is sufficiently loosened to remove by
hand. Remove the printer assembly from the CPU board.

Installing the printer
Before attempting this procedure, ensure that all external cables have been disconnected and the
AccuVote-OS is powered off.
1. Feed the printer ribbon cable connector into the metal frame cavity. Locate the cable
connector onto the header on the CPU board so that the ribbon cable travels towards the rear
of the chassis.
2. Press the connector down, ensuring that it attaches firmly to the header. Verify that the
connector is properly in place and not shifted over by one pin.
3. Slide the printer onto the metal frame so that the printer ribbon cable fits into the underlying
cavity and the two tabs at the front of the printer fit under the heads of the screws on the
mounts.
4. Replace the single screw that was positioned under the right side of the ribbon.
5. Using a Phillips (+) screwdriver, tighten the three screws.
6. Snap the printer ribbon into place in the orientation noted previously in
Removing the printer
.
7. Fold the leading ½” of paper upward and feed into the printer ribbon. Advance the paper in
the assembly by turning the printer thumb wheel clockwise.
8. Replace the unit cover using the procedure previously described in

Removing the ROM chips
ROM chips contain the version of firmware being used by the unit. The AccuVote-OS firmware is
upgraded by replacing existing ROM chips with new ones.
There are two ROM chips on the CPU board:
•
ROM A, installed in the ROM A socket
•
ROM B, installed in the EXP ROM B socket, on top of the SmartWatch ROM chip
Appendix E: ROM Labels
in this guide provides a precise description of ROM labeling.
Before attempting this procedure, ensure that all external cables have been disconnected and the
unit is powered off.
1. Remove the cover using the procedure previously described in
Removing the cover
. Position
the chassis with its front panel facing you.
2. Using an integrated circuit chip pulling tool, gently pry up both ends of the ROM A chip and
the ROM B chip.
