Mechanism Overview 
RR system with non-contact magnet type maintenance-free torque limiter 
Tray Set (Size) 
Detection 
Three switches detect paper size. 
Paper size is fixed by the side fence. Trays 4 and 5 are determined by the 
movement of the detector. Tray 6 can be changed in SP mode. 
Tray is lifted by the lift motor and timing belt. 
It is lowered using a free fall system. 
Remaining Paper 
Detection 
Feeler and four photo interrupters detect remaining paper. 
Detected by a reflex type sensor on the upper stay. 
The clutch is abolished; this is now controlled by a combination of pre-feed 
and main feed based on imaging timing. 
Service option (AC, 15W×2, PTC heater) 
When the tray is overloaded, a bracket stops it from being set in.
