6.5.2 DEVELOPMENT UNIT SENSOR
There are four sensor feelers [A]
located on the front left corner of the
printer. The left end of each feeler
functions as a photo-interrupter. Each
interrupter blocks the development
unit sensor when you set a develop-
ment unit in the printer. The plate
located on the front left corner of the
development unit pushes the feeler.
The left end of the feeler (interrupter)
then moves out of the development
unit sensor. This then activates the
development unit sensor.
