CHAPTER 2 FINISHER UNIT BASIC OPERATION
H.
Detecting the Height of Stack on the Tray
1.
Outline
The number of sheets delivered to the tray and the number of sets (number of stapling operations)
are stored in memory by the finisher controller PCB. The height of the stack is checked by the height
sensor (PS1). See Table 2-204 for the maximum loading capacity of each tray.
sensor (PS1). See Table 2-204 for the maximum loading capacity of each tray.
The finisher controller PCB stops operation when the conditions in Table 2-204 occur, informing
the host machine that the tray is full.
