■ Jam Detection

This machine detects jam using the Document End Sensor (PS02) and the Document
Sensor (PS03). The check timing to detect jam is already stored in the Main Controller PCB,
which determines the occurrence of a jam by the presence of an original in the areas of
corresponding sensors.
When a jam occurs, the machine stores the information by the code.
This machine's jam code can be checked by printing out a jam error history report from
service mode.
