2-6-13. Switching shaft cushion (urethane sheet)
To reduce noise during single folding, a cushion (urethane sheet) is attached to the switching shaft so that the
switching shaft and switching adjusting plate do not touch.
Cleaning the urethane sheet surface with alcohol during cleaning of the folding rollers increases the frictional
coefficient of the urethane surface excessively to exceed the allowed torque of the folding stopper drive motor in some
rare cases. As a result, folding plate 2 may motor lock during initialization (returning of folding stopper to home
position) immediately after power ON.
For this reason, do not clean the urethane sheet surface of the switching shaft with alcohol.
When folding plate 2 motor locks
Wipe the cushion (urethane sheet) surface of the switching shaft with a cloth moistened with grease or oil
(Orelube G90-140), then wipe immediately with a clean dry cloth to reduce the frictional coefficient of the urethane
surface. If no grease or oil is available, move the hand across the urethane surface once.
