Stapling

Stapler

The drive motor in the stapler performs stapling. If motor overload occurs such as for a staple jam, the operation panel shows that a jam was detected. The stapler has a cartridge set sensor and a staple end sensor. The operation panel shows that more staples are needed if staple end occurs during copying. If a staple jam occurs, copying stops. You can remove a jammed staple by releasing the curved part in the picture below..

Staple Trimming

This machine’s stapler uses longer staple needles so that up to a hundred sheets can be stapled. When the stack has only a few sheets, the machine trims the needles to the required length. The cut-off extra part is sent to the staple trimmings tray. When the main power is turned ON, when the door is opened/closed, or after the end of a job that staples over 100 times, the solenoid next to the stapler opens the lever to dump the trimmings into the waste hopper. The staple trimmings hopper descends as it fills, until the staple trimmings hopper full sensor is activated. A message asks the user to empty the staple trimmings.

Stapler Movement

The stapler moves horizontally or rotates, depending on the stapling mode.

• Horizontal Shift
  The stapler moves in the horizontal direction along a rod, driven by a timing belt. The home position of the stapler is the front side. For 2-position stapling, the stapler staples the front side first and then shifts to the rear side to staple there.

Staple Rotation

For the rear corner stapling mode, the stapler shifts to the corner and waits to staple after horizontal shift. The staple rotation motor rotates the stapler to the correct angle.

Stapling Z-folded Paper

The top fence moves before the transferred paper is stacked.

The stack stopper moves to the location that is suitable for the size.

The leading edge of Z-folded paper bumps against the stack stopper.

The positioning roller drops the paper and it is stacked.

When the specified amount of paper is stacked, the top fence moves down. The stack stopper also moves down to straighten the leading edge of the paper.

Output Exit Open/Close

The machine opens the output exit when outputting paper in order to output up to one hundred stapled sheets of paper to the tray.

When the stapler turns ON, the exit open/close motor turns OFF to open the exit, and the feed out motor turns ON after the stapler turns OFF. The feed out motor drives the stack feed-out belt, and the pawl attached to the belt lifts the paper to the exit. A certain time after the stapler turns OFF, the output exit open/close motor turns ON to close the exit, where the paper is output to the shift tray by the exit roller.

In staple mode, the exit opens and close when sixteen or more sheets of paper need to be output.

OFF timing for the output exit open/close motor is detected by the HP sensor.
