[Service work]
Apply quick-drying grease on the whole clutch and assign the paddle drive assembly (FM1-C426-000) as a new spare part on
which the frictional-resistance is reduced.
If the symptom has occurred, prepare and replace with the paddle drive assembly (FM1-C426-000) following the procedure below.
Mind that the following procedure starts from the point after removing the Inner Finisher from the copier main device.
[Points to note] In disassembling the clutch in the paddle drive assembly, be sure not to let the viscous grease attaches inside
the clutch during the work, otherwise the clutch might stop to operate properly.
