PAPER FEED FRAME – INSTALLATION
1. Place the belt cleaner release harnesses back on the printer frame. Be sure to place the wire harness on
the paper feed frame assembly back through the harness guide.
2. Place the wire harnesses back into the PF CR harness. The wide end of the PF CR harness will face the
bottom of the machine when installed. Feed the wire harness back through the printer frame BEFORE
attaching it to the printer frame. Leave slack in the wire harness.
3. Place the frame unit back in the machine with the assembly as far to the RIGHT as possible. DO NOT
push it to the left at this time. Be sure that the metal ground tab for the center screw is not caught under
the frame unit.
4. Locate the white cam shown in figure 1. Use a screwdriver or other object to hold the cam in the UP
position (pushed towards the back of the machine). Leave the cam in this position during the installation
procedure.

7. The goal is to apply only enough pressure to the roller holder assembly to allow the lift arm to rest
between LM hook Aand LM hook B (in red) in figure 4.
Important: If the Left Arm does not go in between the A&B it will not work.
Figure 4
Note: If the roller holder is pushed too far up or not far enough, it will miss this area.
Caution: If the Lift Arm is not inserted properly, the machine will make the original loud noise, and the
machine will not lift the paper tray nor will feed paper.

a. Remove the screwdriver (or other object) used to hold the cam in figure 1.
b. Pushing the roller holder assembly fully to the top of the machine should cause the cam to move
forward. The roller holder assembly should remain locked in the UP position.
c. Pushing the cam toward the back of the machine should cause the roller holder assembly to drop.
The cam should remain in this position.
d. If this behavior is observed, the repair is successful. Secure the frame assembly with the three
screws removed in figure 6. Proceed with reassembly of the machine. LEAVE THE CAM
ASSEMBLY PUSHED TOWARDS THE REAR OF THE MACHINE.
e. If the machine does NOT behave as described, the lift arm is not in the correct position. Repeat the
procedure, beginning with step 5. IT IS NOT NESSCARY TO COMPLETELY REMOVE THE
ASSEMBLY FROM THE MACHINE – SIMPLY SLIDE IT TO THE RIGHT.
Note: Check the bush 7 holder, to make sure it is installed properly and did not clip off.
The Bush 7 is not clipped on properly.
The Bush 7 is clipped on properly.
11. Now you can finish reassembling the machine in reverse order.
