Serial #8199999 and below
STEP PROCEDURE
1. Switch the printer OFF and disconnect the power cable.
2. Remove (3) screws holding the left side cover to the printer. Raise the

4. Raise the media hold-down cover and remove (3) screws to detach the
ramp plate from the ramp frame (mechanical section). Fig. 9-25
5. Remove (3) screws to detach the opposite end of the ramp plate from
back plate (electronics section). Fig. 9-26
NOTE: FOR UNITS WITH DISPENSER OPTION INSTALLED,
IDLER AND GEAR MUST BE REMOVED FOR ACCESS TO THE
3RD SCREW WHICH IS UNDER THE GEAR. REFER TO FIG. 9-27,

switch to the bracket. Install a replacement switch. Fig. 9-33
10. To replace the bottom half of the Notch/Gap and Eye-Mark Sensors,
remove (2) screws that attach the sensor board to the ramp plate. Install a
replacement sensor board. Fig. 9-34
NOTE: If plastic windows are scratched or otherwise damaged, they
should be replaced.
11. Reattach the ramp plate to the ramp frame. Attach all connections from
the sensors to the PCB insuring that SEN7 cable (Paper End Switch),
passes under the paper feed platen and the cable for the gap sensor is
properly routed through notch in ramp plate.
