6.6.2 DEVELOPMENT UNIT SENSOR

There are four feelers [A] on the front
left corner of the copier. The left end
of each feeler operates as an
interrupter. Each interrupter interrupts
the development unit sensor. When
you set a development unit in the
copier, the plate on the front left
corner of the development unit pushes
the feeler. The left end of the feeler
(interrupter) moves out of the
development unit sensor.
