NAME
(3) If this sensor does not detect a leading
edge after feeding from Roll 1 or Roll 2, it also
signals paper end for the roll.
This detects if the spring-loaded lock lever of
the roll feeder drawer is locked.
This reflective photosensor above Roll 1
detects the core of the roll (which is black),
after there is no more paper on Roll 1.
This reflective photosensor above Roll 2
detects the core of the roll (which is black),
after there is no more paper on Roll 2.
Detects the trailing edge of the roll after there
is no more paper on Roll 1. This sensor is
included because if the color of the roll core is
not black, Roll End Sensor 1 cannot always
detect roll end.
Detects the trailing edge of the roll after there
is no more paper on Roll 2. This sensor is
included because if the color of the roll core is
not black, Roll End Sensor 2 cannot always
detect roll end.
Detects toner overflow in the used toner
collection bottle.
Detects when the upper unit is open.
The actuator of this sensor is attached to the
wire that moves the transfer cleaner from left
to right. This tells the machine when the wire
cleaner moves.
