section

1)Proof branch, staple branch

The paper path is selected between the path to the proof tray and the path to the upper tray depending on presence of sort or staple.

2)Proof tray

When the sort mode and the staple mode are not selected, copy paper is discharged to this tray.

3)Tray assembly

This tray lifts up or moves down in the sort mode depending on the copy discharge quantity (the number of copy sets).

4)Tray paper folding section (The MX-FNX7 only)

Center binding copy is discharged to this tray in the sort mode.

5)Pre-stack section

The first page of the second or later sets is switch-back transported and kept in standby, and fed together with the second page to the staple tray.

6)Center binding staple section (The MX-FNX7 only)

Sheets of copy paper are aligned by the alignment roller and the jogger fence, performing stapling.

4. Branch mechanism

1)Paper is branched to the three directions by the proof branch pawl and the staple branch pawl.

2)In the proof mode, when discharging to the proof tray, copy paper is transported to the proof tray by the proof branch pawl.

When in the proof mode:

Staple branch pawl

Proof branch pawl

3)In the shift mode, the proof branch pawl and the staple branch pawl do not operate, and copy paper is transported to the shift tray.

In the shift mode:

MX-FNX6 MECHANISM 3 – 3

4)In the staple mode, the staple branch pawl operates to transport copy paper to the staple section.

In the staple mode:

Staple branch pawl

5. Pre-stack mechanism

Four sheets can be discharged with max. three sheets of pre-stack. In the example below, descriptions are made on discharge of three sheets with two sheets of pre-stack.

1) Stapling the first set is performed.

2nd sheet of 2nd set

1st sheet of 2nd set

Bundle of 1st set

2)The first sheet of the second set is switch-back transported to the pre-stack tray.

Pre-stack tray

3)The first sheet of the second set is transported from the prestack tray. At the same time, transport of the second sheet of the second set is started.

4)Transport of the first sheet of the second set is completed. At the same time, the rear edge of the second sheet of the second set passes the branch pawl.

Pre-stack Branch pawl

5)The first sheet and the second sheet of the second set are switch-back transported together to the pre-stack tray.

6)Stapling of the first set is completed. At the same time, the first sheet and the second sheet of the second set are transported together from the pre-stack. Transport of the third sheet of the second set is also started.
