Paper Jam Detection

C9000 detects paper jams after power-on and during printing.  When a paper jam occurs, the
printer immediately suspends the printing operation.  Opening the cover to remove the jammed
paper and closing it resumes the printing.

Description

The entrance cassette sensor does not turn off within fixed time
after it turns on.  Loading of plural sheets of paper is sensed.
Paper could not be loaded from the duplex carrier assembly.
Paper could not be loaded from the MT (the entrance MT 
sensor does not turn on within fixed time after the hopping).
Paper could not be loaded from the cassette 1, 2, 3, 4 or 5 (the 
entrance cassette sensor does not turn on within fixed time after 
the hopping).

The duplex rear sensor does not turn on during the paper 
reversing operation of the duplex unit.
The duplex-in sensor does not turn on during the paper loading 
in the duplex unit.
The duplex front sensor does not turn on during the operation.
The paper eject sensor does not detect the end of paper within 
fixed time after sensing the beginning of it.  The paper eject 
sensor does not turn off after it turns on.
The paper eject sensor does not turn on while paper is running 
on the belt.
Paper does not reach the entrance belt sensor or the MT sensor 
after the completion of the hopping.
Printing occurs with no paper in the MT.
The cassette 1, 2, 3, 4 or 5 has no paper.
