2.2.3 POSITIONING ROLLER
Positioning Roller Mechanism
The positioning roller [1] (driven by the transport motor) is mounted on the positioning roller
arm [2] that swings freely on the shaft [3].
The positioning roller arm motor [4] drives a cam [5]. The eccentric rotation of this cam
raises and lowers the coupler [6] that pushes against the positioning roller arm [7]. This
motion raises and lowers the rotating positioning roller as the cam turns through one full
rotation.
An actuator [8] attached to the cam wheel deactivates the positioning roller HP sensor [9]
and stops the motor. This stops the positioning roller arm and positioning roller at the
highest point (home position).
When the positioning roller is lowered:
The transport motor slows down to match the speed of the main machine's exit roller.
At the same time, the positioning roller motor accelerates briefly, lowers the positioning
roller arm and then stops.
When the positioning roller touches the paper:
The positioning roller (driven by the transport roller) continues to rotate.
The positioning roller (and the smaller two sponge rollers), rotating against the
direction of paper feed, touch the paper and send it back against the bottom fences.
The number of sheets that stack on the staple tray while the positioning roller motor is
stopped is different for each job.
To meet the requirement for the increasing number of sheets, the length of prescribed
time that the positioning roller is in contact with each sheet of paper is very short,
regardless of the size of the stack.
The positioning roller arm motor remains off just long enough for the positioning roller
to send the sheet against the bottom fences.
