EJ Roller Gear
The rib on the contact point of the EJ Roller Gear with the EJ
Roller is deformed when removing the EJ Roller Gear. Therefore,
make sure to replace it with a new one when removing it in order to
maintain the paper feed accuracy.
Can not be reused because the rib
of the EJ Roller Gear is deformed
once removed from the EJ Roller.

PF Encoder Sensor / PF Scale
Do not reuse the removed PF Scale and make sure to replace it with a new one when removing it.
When installing the PF Scale, it is pressed into the PF Roller, therefore, the removed one is deformed. If it is re-installed to the printer, it does not
rotate properly and the paper feed accuracy may be reduced.
When installing the PF Scale to the PF Roller, press the PF Scale into the PF Roller vertically.
After installing the PF Encoder Sensor, confirm the PF Scale does not touch the PF Encoder Sensor.

PF Driven Pulley Assy / PF Timing Belt
Do not hold the PF Driven Pulley Assy when securing it with the screw in order to prevent applying improper tension to the PF Timing Belt.
When installing the PF Driven Pulley Assy, follow the procedure below.
1. Align the rib of the PF Driven Pulley Assy with the hook of the PF Motor Frame, and install the PF Driven Pulley Assy.
2. Attach the Compression Spring 5.07 to the protrusion of the PF Driven Pulley Assy and the dowel of the PF Motor Frame.
3. Attach the PF Timing Belt in the order of the pinion gear of the PF Motor, PF Driven Pulley and Combination Gear 29.2,42.
4. Rotate the Combination Gear 29.2,42 clockwise three times to confirm the PF Timing Belt is correctly attached, and then secure the PF Driven
Pulley Assy with the screw and washer to the PF Motor Frame.
