Replacement Procedures and Parts
Control Panel (29–29286–01)
1. Unplug the printer power cord from the AC receptacle to insure that
there are no hazardous voltages present while servicing this equipment. It
is also recommended that an anti–static wrist strap (29–26246–01) be
worn, especially while servicing logic components.
2. Using a 5/16” wrench or nut driver, loosen the 4 screws which hold the
control panel in place. (See Figure 6–15, page 6–56.)
3. Remove the front panel (Figure 6–6, page 6–38), from the cabinet to gain
access to the card cage. This is accomplished by loosening the retaining
screw located inside the top of the cabinet, directly below the control
panel. Lift and pull the panel away from the printer to remove.
4. Remove the card cage access panel by removing the five (5) screws
which hold it in place. Follow the control panel ribbon cable to the berg
connector on the front edge of the CCB PCBA.
5. Remove the connector from the module, and cut the necessary tie–wraps
to free the cable. Remove the cable and control panel from the printer.
6. Reverse the removal steps to install the new control panel.
NOTE: Before tightening the screws that secure the control panel to its
bracket, close the printer cover and center the control panel in the
cutout.
