30 Finisher unit explanation ENWW

b Second set:

The stapling operation for the first set is

activated, and, after a predefined time,

SD705 (bypass gate) is activated to pull

the first sheet of the second set toward

the bypass.

SD705 stops it operation when a

predefined time has elapsed since

PS704 (finisher entrance) detected the

rear end of the first sheet of the second

set.

SD705 does not operate when the

second and subsequent sheets of the

second set are processed.

c Third and subsequent sets:

PS704 (finisher entrance) detects the

rear end of the last sheet of the second

set. Then, after a predefined time,

SD705 (bypass gate) is activated to pull

the first sheet of the third set toward the

bypass.

SD705 stops it operation when a

predefined time has elapsed since

PS704 (finisher entrance) detected the

rear end of the first sheet of the third

set.

SD705 does not operate when the

second and subsequent sheets of the

third and subsequent sets are

processed.

2 Signals

a Finisher CB output signals

1 PS705 DRV (finisher CB to SD705)

Signal to drive/control the SD705.

[H]: SD705 is on.

[L]: SD705 is off.

M702 (shift) control

M702 (shift) performs the paper offset

operation in the sort or group mode.

The finisher CB (finisher control board)

controls M702.

The related signals are PS704 (finisher

entrance) and PS718 (shift HP).

1 Operation

In the sort or group mode, PS704 (finisher

entrance) detects the rear end of the

paper. After a predefined time period,

M702 (shift) operates. Its rotation triggers

the shift (travel) of the shift moving

section. The shift roller, rotated by M701

(finisher conveyance), carries the paper

while the shift operation is being

performed.

The completion of the shift operation is

detected by the change of PS718 (shift

HP) signal, from off to on, and then M702

is deactivated.

After a predefined time period has elapsed

since M702 was deactivated, it is

activated again. M702 stops when PS718

(shift HP) signal changes from on to off.

This operation allows the shift moving

section to return to its original position to

wait for the next paper to be shifted.

This sequence of actions is repeated for

each sheet to achieve offsetting of paper.
