[1] PRODUCT OUTLINE
Service Manual
This unit is used by installing to the main unit for after-process of copy and FAX output paper. It is provided with the offset function which discharges output paper by shifting one by one.
Since it is installed to the center tray section of the main unit, no extra space for installation is required.
1) 3 kinds of auto staple functions: There are 3 kinds of stapling positions. (One position in front, one position backward, 2 positions at the
center).
2
2) Punch function (option): By installing the punch unit, paper can be punched to make binder holes. (Paper of 64 to 128g/m
can be used.
OHP film cannot be used.)
Models enable to install the unit MX-2300G/2700G/2300N/2700N
The finisher requires a staple cartridge as a consumable part. (Staple cartridge (about 5,000 staples x 3 pcs.) MX-SCX1)

2. General
This chapter describes operations of the inner finisher. The major operation modes are as follows:
• Non-sort mode
• Offset mode
• Staple mode
• Non-sort mode + punch
• Offset mode + punch
• Staple mode + punch
In this chapter, the basic operations of the non-sort mode, the offset mode, and the staple mode are described.

4. Non-sort mode
When the operation mode command is received from the copier,
the finisher makes the finisher operation status command the JOB
and starts the transport operation.
A. Reception of paper discharged from the main
unit
1) The transport motor (FRM) is driven at the paper exit speed of
the main unit to receive paper from the main unit.
2) Immediately after the paper rear edge passes the bundle exit
roller, the paddle one-rotation solenoid (FPDS) is turned ON to
take-up the paper falling onto the tray.
3) When paper is transported by 10mm after the paper rear edge
passes the bundle exit roller, the bundle exit motor (FAM) is
accelerated to 200mm/sec. Just before the paddle passes the
load tray, the paper surface detection solenoid (FSLS) is
turned ON to hold the paper discharged by the paper holding
lever.

a certain amount is made, the alignment plate is shifted to the
home position.
Before the paper rear edge passes the bundle exit roller, the
paper surface detection solenoid (FSLS) is turned OFF and
the bundle exit roller speed is decelerated to 100mm/sec at the
same time, performing paper exit deceleration of paper.

6) When the paddle rotates one turn, the bundle exit motor (FAM)
is stopped.
7) When there is next paper, the procedures are repeated from
"A-1)."
8) When there is no next paper, the actuators are turned OFF and
the finisher operation status command is set to READY to terminate the transport operation.
6. Staple mode
When the operation mode command is received from the copier,
the finisher makes the finisher operation status command the JOB
and starts the transport operation.
A. Reception of paper discharged from the main
unit
1) The transport motor (FRM) is driven at the paper exit speed of
the main unit to receive paper from the main unit. When the
paper length is 216mm or less, the paper exit speed of the second and later sheets from the main unit is 280mm/sec.
