Descriptions
(1 of 2)
The table below describes the photo-interrrupter sensors used in the
Color LaserWriter 12/600 PS and the optional sheet feeder. All of these
sensors consist of two basic elements, one electrical (a U-shaped, light-
emitting sensor), and one mechanical (a flag that is actuated by some
other movement within the printer).
When the “flag” of the actuator passes into the U, the flag interrupts the
light and the controller reacts accordingly. When troubleshooting this
type of sensor, first check that the mechanical actuator is free to move
and is not broken, then concentrate on the electrical elements.
