CHAPTER 2 FINISHER UNIT BASIC OPERATION
L.
Detecting Jams
The following sensors are used to detect the presence/absence of paper and to make sure that
sheets are moved properly.
●
Inlet sensor (PI1)
●
Delivery sensor (PI3)
●
Stapling tray sensor (PI4)
●
Buffer path paper sensor (PI14)
●
Buffer path inlet paper sensor (PI7)
A jam is identified with reference to the presence/absence of paper at each specific sensor at
such times as programmed in the memory of the microprocessor (CPU) on the finisher driver PCB.
When the CPU identifies a jam, it suspends the finisher’s delivery operation and informs the
options controller of the presence of a jam.
The tray 1 paper sensor (PI11), tray 2 paper sensor (PI12), and tray 3 paper sensor (PI13) are
not used to detect jams.
