The bind tray in the saddle unit is of the fixed type and all the folded
paper stacks are delivered to this tray. This tray has a bind tray sensor
(FES) to detect presence/absence of paper.
(FES) to detect presence/absence of paper.
The delivery tray in the finisher unit is moved up and down using a shift
motor (FLM).
The finisher has a tray paper sensor (BES) to detect presence/absence
The finisher has a tray paper sensor (BES) to detect presence/absence
of paper on the stack tray.
The home position sensor of the delivery tray is detected by the paper
surface sensor (STHPS). When paper has already been stacked on the
surface sensor (STHPS). When paper has already been stacked on the
delivery tray, the home position is on the top surface of the stacked
paper. When paper has not yet been stacked on the delivery tray, the
home position is at the position where the edge of the delivery tray is
home position is at the position where the edge of the delivery tray is
detected. At power-on, the finisher controller PCB drives the shift motor
(FLM) to return the delivery tray to the home position.
When the paper coming from the processing tray is stacked on the
When the paper coming from the processing tray is stacked on the
delivery tray, the shift motor is driven a specified number of pulses,
causing the delivery tray to descend. Clock pulses are detected by the
shift motor clock sensor (LE). Then, the delivery tray returns to the home
shift motor clock sensor (LE). Then, the delivery tray returns to the home
position for the next stacking operation.
The upper limit of the delivery tray is detected by the shift upper limit
sensor (ULS). When the shift upper limit sensor (ULS) is turned ON, the
sensor (ULS). When the shift upper limit sensor (ULS) is turned ON, the
finisher controller PCB stops the shift motor (FLM) that is ascending.
The lower limit of the delivery tray is detected by the shift lower limit
sensor (LLLS). When the shift lower limit sensor (LLLS) is turned ON,

the finisher controller PCB stops the shift motor (FLM) that is
descending.
The finisher unit has a full stack sensor (PI24) to detect overstacking of
The finisher unit has a full stack sensor (PI24) to detect overstacking of
large-size or mixed paper according to the stack height.
D. Saddle Unit
(1) Basic Operations
a. Outline
The machine stitches a stack of sheets (middle 2-point), then folds the
stack in two in the finisher. These operations are controlled by the
stack in two in the finisher. These operations are controlled by the
finisher controller PCB.
The finisher controller PCB is controlled by the commands from the host
machine.

(2) Feed/Drive System
a. Outline
This machine stitches the paper stack coming from the finisher, folds it,
and delivers it to the bind tray in the saddle unit in response to the
commands from the host machine.
