Puncher section and Stapler section

1. Basic mechanism of Puncher section

1-1. Paper transport in Puncher section
• Paper transported from the ComColor passes through the I/F Module, and then to the Entrance Roll to the
Puncher section.
• The Entrance Roll receives drive power as described below.
• The Entrance Roll is driven by the Assist Roller Drive Motor in the I/F Module.
• The paper entering into the Puncher section is detected by the Decurler OUT Sensor in the I/F Module.
• Paper is then transported to the direction of the Top Tray or Stacker Tray via the Punch Reverse Roll. (The
paper is not transported toward the Booklet tray when punched or stapled.) During this process, the paper
transport status is detected by the Punch OUT Sensor, located after the Puncher.
• After a certain period elapses from the time the trailing edge of the paper leaves the Decurler OUT Sensor
(before the trailing edge of paper passes the Puncher Pins), the Finisher Transport Motor, SCT Exit Motor, and
Compile Exit Motor activates in the reverse direction, rotating the rollers after the Puncher Unit, including the
Punch Rev. Roll in the reverse direction, to bring the paper back towards the Puncher Unit until the trailing edge
of the paper contacts the Puncher Guide. This corrects paper skew and sets the paper into the correct punching
position. (For the Motor locations, refer to the diagram on the Top Tray section -- Page No. 24-37 & 24-38.)
• The Staple Guide give away to the paper and folds flat to make the path for the paper when the paper from
the printer comes into the Puncher, allowing the paper to pass. But when the paper is pulled back against the
Puncher Guide for the punching, Puncher Guide does not fold, but acts as a stopper to align the papers.
* The amount of punch reverse travel (amount of reverse operation) can be adjusted by using Test Mode No.
4739 "PUNCH RESERVE ADJ 1" and No. 4762 "PUNCH RESERVE ADJ 2".
made too much to the (+), the paper tends to get stained. If adjusted too much to the (-), the punching

• The paper is transported toward the Top Tray or Stacker Tray after the punch holes are made on the trailing
edge of the paper.
