Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Check. Remove the claw.
Check visually. Insert the claw.
Check the noise. Use the bundled part.
Disconnect the connector. Push the part.
Connect the connector. Plug the power cable.
Remove the cable/wire

The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the
relationship between electrical and mechanical systems with reference to the timing of
operation.
In the diagrams, represents the path of mechanical drive; where a signal name
accompanies the symbol, the arrow indicates the direction of the electric signal.
The expression "turn on the power" means flipping on the power switch, closing the
front door, and closing the delivery unit door, which results in supplying the machine with
power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is
"High", while '0' is used to indicate "Low". (The voltage value, however, differs from
circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD
signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked
in the field. Therefore, the operations of the microprocessors used in the machines
are not discussed: they are explained in terms of from sensors to the input of the DC
controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product
improvement or other purposes, and major changes will be communicated in the form of
Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service
Manual and all relevant Service Information bulletins and be able to identify and isolate faults
in the machine.

This equipment is mainly consists of a feed block, trimming block, paper delivery block, and
waste paper stack block.
Feed block
[1]
Receives the booklet stitched by the saddle stitcher, and then delivers it to
the next block.
Trimming
block [2] Trims the fore edge of the stitched booklet. * When trimming is not done, the booklet just passes through the trimming
block.
Paper
delivery
block [3]
Applies pressure on the press rollers during transfer, delivery, registration,
and trimming of the stitched booklet.
* When trimming is not done, registration of the booklet is not done either.
Waste paper
stack block
[4]
Collects the waste paper generated when fore edges of booklets are
trimmed.

Basic Operation Outline
This equipment trims the fore edge of the stitched booklet, and then delivers the booklet to
the saddle delivery tray.
This equipment is optionally available and installed in the feed path inside the saddle nisher.
When the booklet stitched by the saddle stitcher is fed to this equipment, registration is
performed to be prepared for trimming. After this, the booklet is trimmed with it held down by
press rollers and then delivered to the saddle delivery tray. These operations are controlled
by the trimmer controller PCB.

Overview
This unit is installed between the saddle unit and saddle delivery tray of the saddle nisher. It
stops the center bound booklet for a moment to trim the fore edge.
The booklet loaded from the saddle unit is fed by the inlet roller. When the leading edge of
the media (back of the booklet) reaches a prescribed location, the booklet is stopped for a
moment and registered. Then it is fed to the trim position and the fore edge of the booklet is
trimmed.
The name and role of motors, solenoids, and sensors used for trimming are shown below.
