4.18 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, reflective type, and it functions like this: A little infrared lamp is sending

light downward. If there is paper present, the light will be reflected back, and detected by a photo tran

sistor. If the sensor is defective, it must be replaced. It can be done like this:

Take the paper guide out of the printer. Unscrew first the screws (A), then (B) and then (C). Now the

sensor is loose. The assembly is done in reverse order.
