CHAPTER 2 OPERATIONS
III . DETECTING JAMS
The machine uses the sensors shown in Figure 2-303 to check for original jams. The machine
checks for jams at such times as programmed in the CPU on the ADF controller PCB, and a jam is
identified in reference to the presence/absence of an original over each appropriate sensor.
When a jam is detected, the machine communicates its presence to the copier. (Some copiers
allow checking of such codes in service mode. Or, the indicator (LED2) on the machine's ADF
controller PCB may be used to check the code.)

The indicator (LED2) on the ADF controller PCB expresses codes by turning on four times,
each time flashing a different segment(s).
