4-9-3.
FEED ROLLER OPEN MOTOR (DCM4)
Special Tools
9-volt DRY CELL BATTERY
Preliminary
1. Remove the SUPPLY CARTRIDGE.
!
Warning
When the POWER CORD is plugged in, hazardous voltages are present in some areas of the
IMAGER. These voltages can cause severe injury or death.
2. De-energize the IMAGER and disconnect the POWER CORD.
3. Remove the FEED ROLLER MODULE (4-9-1).
Disassembly
1. Move the VANE out of the SENSOR:
a. Use a 9-volt DRY-CELL BATTERY to operate the FILM FEED MOTOR to drive the VANE out of
the SENSOR. (See positions of the SENSOR VANE in Figure 4-34.)
Note
Insert a PAPER CLIP in each of the 2--PIN SOCKETS of the MOTOR CONNECTOR (Figure 4-34),
and place the BATTERY TERMINALS across the 2 PAPER CLIPS to apply power to the FILM
FEED MOTOR.
b. When the VANE has moved out of the SENSOR, remove the BATTERY and PAPER CLIPS.
2. Loosen the SETSCREW that attaches the VANE and CAM to the MOTOR SHAFT (Figure 4-34).
3. Pull the VANE and CAM from the MOTOR SHAFT.
4. Remove the MOTOR ELECTRICAL CONNECTOR from the CHASSIS.
5. Remove 3 ATTACHING SCREWS and remove the FILM FEED MOTOR.
Reassembly
1. Position the FILM FEED MOTOR as shown in Figure 4-34 and attach it with the 3 SCREWS.
2. Make sure that the flat on the MOTOR SHAFT is positioned so that the FEED ROLLER OPEN
SENSOR will not interfere with installation of the CAM and VANE on the MOTOR SHAFT.
Note
If you have to reposition the MOTOR SHAFT, use a 9-volt BATTERY to drive the FILM FEED
MOTOR as described in step 1 in Disassembly above.
3. Install the CAM and VANE on the MOTOR SHAFT and secure it by tightening the SETSCREW
against the flat of the MOTOR SHAFT.
4. Install the MOTOR ELECTRICAL CONNECTOR in the CHASSIS, and replace the MOTOR DRIVE BELT.
