3.2.2 PAPER PATH WITH Z-FOLDING
The feed rollers [1] feed the paper from the main machine into the Z-folding unit.
The junction gate solenoid energizes and opens the junction gate [2]. The junction
gate sends the sheet down into the Z-folding paper path.
The upper and lower stopper motors move the upper stopper [3] and lower stopper
[4] to the positions for the paper size that was used for the job.
The feed sensor [5] detects the leading edge and trailing edge of the sheet. The
pinch idle roller solenoid (upper) pulls the pinch idle roller [6] away from the pinch
feed roller [7] and the paper can fall between the pinch rollers.
The anti-static brush [8] removes static electricity from the sheet.
When the fold timing sensor [9] detects the trailing edge of the sheet, it energizes
the pinch idle roller solenoid (lower). This pushes the pinch idle roller [6] against
the opposite pinch feed roller [7].
The lower stopper [10] stops the sheet and buckles it slightly toward the nip [11] of
the 1st and 2nd fold rollers.
