4.19 Paper sensor, replacing

This printer has a sensor to detect if paper is present in the printer.
This sensor is situated on the paper guide where the paper enters the printer.
The sensor is an infrared, refl ective type, and it functions like this: A little infrared lamp is sending ligth
downward. If there is paper present, the ligth will be refl ected back, and detected by a photo transistor.
If the sensor is defective, it must be replaced. It can be done like this:
Take the paper guide out of the printer. Unscrew fi rst the screws (A), then (B) and then (C). Now the
sensor is loose. The assembly is done in reverse order.
