It has the following functions: Paper discharge to a selected tray,
paper reversion, stapling for paper delivered to the offset tray (3
positions), offset, and elevation. Each function is performed according
to the mode instructed by the copier.

A. Upper paper transfer section
1) Paper transfer
By rotating the main driving motor (FM), the transfer rollers in the
finisher are driven.
finisher are driven.
The transfer speed is switched over between the copier speed mode
and the high-speed mode according to the paper discharge mode
and paper size.
and the high-speed mode according to the paper discharge mode
and paper size.
2) Paper entry gate (4)
The paper entry gate (4) is operated by the paper entry sole-
noid(INGSL) to select the upper transfer (outside route) and rever-
sion/short path according to the mode.

3) Paper discharge gate 1 (1)
The paper discharge gate 1 (1) is operated by the paper discharge
gate 1 solenoid (OG1SL), to select between the routes for paper
discharge to the tray 1 (10) and transport to the tray 2 (7)/staple tray.

4) Paper discharge gate 2 (8)
The paper discharge gate 2 (8) is operated by the paper discharge
gate 2 solenoid (OG2SL) to select between the routes for paper
discharge to the tray 2 (7) and transport to the staple tray.

discharge to the tray 2 (7) and transport to the staple tray.
5) Trays 1 (10) and 2 (7) paper discharge operation
When paper is delivered to the trays 1 (10) and 2 (7) at a high-speed
in the 3 tray finisher, the trays 1 and 2 deceleration clutch (13) is
operated at paper delivery timing to decelerate the paper discharge
rollers 1 and 2 in order to align the paper to the trays 1 (10) and 2 (7)
with high accuracy.
