3.2.4
Single-sheet mode
SFR The pushbar moves to position 6, at which point the tractors are idle, and the friction
is switched on. The pushbar then moves to position 5. The gear (76) moves to posi-
tion 2 (away from the side wall), thus rendering inactive the gear (77) used to drive
tractor 3. The only operative gear (74) is the one used to drive the SFR. The LF
motor moves back and forth to synchronise the SFR clutch in load position.
SFF The pushbar moves to position 6, and the gear (82) is lifted (position 2) and swit-
ches to friction. Paper is transported to the PE sensor position by reverse steps of
the LF motor. Then the sense of rotation is inversed. Paper transport is effected by
friction, the SFF is in the free-wheel position. The paper transport in the SFF is only
activated for printer reverse motion. If much paper is to be fed back, pushbar posi-
tion 5 is used.
Manual sheet feeder The pushbar moves to position 6, and the gear (82) is lifted (position 2) and swit-
ches to friction. The manual sheet feeder transports paper to the PE sensor. The
pushbar then returns to position 5, the gear (82) moves centre between the position
against and away from the wall and the paper is pulled in by means of the friction.
3.2.5
Changeover to tractor
mode
If tractor mode is to be re-engaged, the pushbar moves to its initial position (1) and
both frictions are switched off. Tractor selection can then commence.
3.2.6
Changeover to AGA
mode
As soon as the carriage moves to the right, the motor FAW starts the AGA. The
gear (72) in the seesaw is fixed in position when the FAW motor is switched to
AGA.
