Detecting Jams

■ Jams
This machine detects document jams using the sensors shown below.
Document jam check timings are stored in the ROM on the reader controller PCB to check
whether a jam has occurred according to presence/absence of a document at the relevant
sensor position.
When a jam occurs, the host machine stores its code.
Jam codes can be checked by outputting a jam error log report in the service mode of the
host machine.
