6.2.5 PRE-FOLD TRANSPORT MODULE
When the stapling is done, the side guides motor M3 moves out.
The staple stop gate motor M22, moves the transport rollers upwards,
gripping the set between the transport roller below and idler roller on top of the set.
The staple stop gate is pulled down by the same motor and latched below the paper path.
The set transport motor M5 starts and transports the set down to the fold stop.
Fold stop sensor Q7 (see Folding Module) near the fold stop, activates.
Side guides M3 move out to their initial position.
In case the sheet length is shorter than the distance between staple stop and fold stop (i.e. A4),
the staple stop will unlatch as soon as the set has cleared the Start Sensor Saddle Stapling Q4.
The staple stop is unlatched by the staple stop gate motor M22.
In case the sheet length is longer than the distance between staple stop and fold stop (i.e. A3),
the staple stop gate motor M22 will release the transport wheel pressure as soon as the set has
reached the fold stop gate.
When the set is folded and leaves the Start Sensor Saddle Stapling Q4,
the staple stop gate moves up, preparing to receive new sheets.
By stopping in variable positions, different staple positions can be obtained.
