1.2 Operation
1.2.1 Conveyance 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 t he main body’s fixing roller and the FNS conveyance roller, the
M701 (FNS conveyan ce motor) opera tes at the speed of 230 mm/s accor ding to the mai n body line
speed. When the paper passes through the fixing roller, the M701 operates at the speed of 600 mm/s.

• While the paper is nipped to both t he main body’s fixing roller and the FNS conveyance roller, the
SD701 (Roller releas e solenoid) i s turned on to r elease the nip of the FNS conv eyance rolle r for the
increased productivity of sorting, grouping and stapling.

paper exit opening.
If the shutter opens whi le the tray is g oin g up or d own, the MS 702 (Shu tter s wi tch ) is tur ne d o n to sh ut o ff

3.2 Operation
3.2.1 Paper 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 independentl y by the M704 (Align ment motor /F) and the M703
(Alignment motor /R). For straight al ignment of the sorting, grou ping, and stapling oper ation, 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 ali gnment pl ates are de tected by the PS709 (Al ignmen t HP sensor /R) and the
PS710 (Alignment HP sens or /F).
A. Straight alignment operation
Small size paper such a s 5.5 x 8.5R, A5R or B5R is stacke d and aligned to prevent the p aper from
having uneven edge after being exited.
II UNIT EXPLANATION
During the paper exi t, the alignment plate /F and the alignment plat e /R move symmet rically in front
and in rear based on the center of the alignme nt sect ion with al ternatio ns of ali gnment an d alignm ent
release. Aligned papers are exited for every 5 sheets.
