1.2Operation

1.2.1Conveyance control

Conveyance controls can be roughly divided into the following 2 patterns:

A. Pattern 1: Normal conveyance control

•While the paper is nipped to both the main body’s fixing roller and the FNS conveyance roller, the M701 (FNS conveyance motor) operates at the speed of 230 mm/s according to the main body line speed. When the paper passes through the fixing roller, the M701 operates at the speed of 600 mm/s.

B. Pattern 2: Conveyance control of small-sized paper with paper intervals narrower

•While the paper is nipped to both the main body’s fixing roller and the FNS conveyance roller, the SD701 (Roller release solenoid) is turned on to release the nip of the FNS conveyance roller for the increased productivity of sorting, grouping and stapling.

2.2.2Paper stack control

While in the sort mode, group mode or staple mode, paper conveyed to the paper exit opening is conveyed to the stack section by the backward rotation of the paper exit roller /A [1]. The paper thus conveyed is sent up to the stopper [3] by the frictional force of the conveyance belt [2] to be stacked.

2.2.3Shutter control

While the tray is going up or down, the shutter [1] is driven by the backward rotation of the M707 (Pressure motor) to close the paper exit opening. This is to prevent accidents such as the hand being caught in the paper exit opening.

If the shutter opens while the tray is going up or down, the MS702 (Shutter switch) is turned on to shut off the power of 24VDC and the FNS is immediately stopped.

ALIGNMENT SECTION

3.2Operation

3.2.1Paper alignment control

Paper stacked by the paper exit roller /A is aligned by the alignment plates. The alignment plates provided in front and rear, one for each, are driven independently by the M704 (Alignment motor /F) and the M703 (Alignment motor /R). For straight alignment of the sorting, grouping, and stapling operation, the paper moves symmetrically in front and in rear, and is aligned at the center by the alignment plates and it moves asymmetrically while in the shift mode.

The home positions of the alignment plates are detected by the PS709 (Alignment HP sensor /R) and the PS710 (Alignment HP sensor /F).

A.Straight alignment operation

Small size paper such as 5.5 x 8.5R, A5R or B5R is stacked and aligned to prevent the paper from having uneven edge after being exited.

During the paper exit, the alignment plate /F and the alignment plate /R move symmetrically in front and in rear based on the center of the alignment section with alternations of alignment and alignment release. Aligned papers are exited for every 5 sheets.
