* 4. Pickup roller / feed roller / separation roller
When installing the pickup roller and feed roller, pay attention to allocate the pickup roller,
gear, feed roller and one-way clutch correctly.
When replacing the separation roller, replace only the roller and continue to use the torque
limiter.
* 5. Drive gears in the paper feeding section (teeth face and shafts)
Apply some white grease (Molykote X5-6020) to the teeth faces and shafts of the drive
gears.
Note: Note:
Make sure that oil is not running over or scattered around as the gear is rotated coming into the
clutch after applying molykote to the gear which is located near the clutch. The quantity of
molykote should be smaller than that to be applied to the other parts.
