2.7 Detecting Jams
2.7.1 JAM
0004-5590
The machine checks for an original jam using the sensors shown in the figure. The timing
at which a check is made is programmed in the ROM on the reader controller PCB, and the
presence/absence of a jam is identified in terms of whether there is paper over a particular
sensor.
when it detects a jam, it communicates the fact to its host machine using a code, which may
be checked in the host machine's service mode.
