Paper feed roller
Separate sheet
The paper feed roller is of circular form, and double paper feed is prevented by the separate sheet.
Paper feed clutch lever
Clutch R sleeve
The paper feed clutch lever is provided to prevent the paper feed roller from rotating reversely. When paper feed is not performed, the paper feed clutch lever is engaged with the paper feed roller boss gear.
When removing paper for paper replacement, a reverse rotation power is applied to the paper feed roller. In this case, the paper feed solenoid provides enough power to prevent the paper feed roller from rotating reversely, however an excessive stress is applied to the spring clutch, which may be damaged. Therefore the paper feed clutch lever is used to lock and protect the spring clutch from an excessive stress.
