I/O Panel and Cable Assembly (29–30893–01)
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. Remove the paper supply from the print station and tractors. Remove the
paper chains, paper tent, and wire paper guide.
3. As shown in Figure 6–17 (page 6–60, item #2), remove the inner access
panel by removing seven (7) 5/16” screws.
4. Remove the four (4) 5/16” retaining screws from the I/O panel assembly,
and rest the panel on the inside of the cabinet floor.
5. 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.
6. Remove the card cage access panel by removing the five (5) screws
which hold it in place.
7. Follow I/O panel ribbon cable to the berg connector on the front edge of
the CCB PCBA module, and remove. Pull this end of the cable through
the side of the card cage to free the I/O panel assembly from the printer.
