Page 674: Separation Roller And Pick-Up Roller Release
SEPARATION ROLLER AND PICK-UP ROLLER RELEASE 2.3 SEPARATION ROLLER AND PICK-UP ROLLER RELEASE B600D107.WMF B600D108.WMF To prevent the paper from being torn when pulling out the paper feed tray, the separation and pickup rollers are set so that they release automatically. When the paper tray [A] is not inside the machine, the separation roller [B] is away from the paper feed roller [C] and the pick-up roller [D] stays in the upper position.
Page 675: Tray Lift
TRAY LIFT 2.4 TRAY LIFT B600D103.WMF When the paper feed tray is put in the machine, the tray sensor on the back face turns on and the tray lift motor [A] starts. The base plate lift shaft [B] is coupled to the lift motor at shaft [C], so the base plate of the tray is lifted.
Page 676: Near End/End Detection
NEAR END/END DETECTION 2.5 NEAR END/END DETECTION This tray holds two stacks of paper, so the machine needs to monitor the status of both these stacks. There are seven sensors to do this. In the right tray (paper feed side), three height sensors ([E] in the diagram on the previous page) measure the height of the stack, and an end sensor detects when all the paper is used up.
Page 677: Paper Stack Transport Mechanism
PAPER STACK TRANSPORT MECHANISM 2.6 PAPER STACK TRANSPORT MECHANISM B600D104.WMF When the paper in the right tray is used up, the tray motor [A] and stack transport clutch [B] turn on. Then the rear fence [C] moves the stack of paper from the left tray to the right tray.
Page 678: Right Tray Paper End Detection
RIGHT TRAY PAPER END DETECTION 2.7 RIGHT TRAY PAPER END DETECTION B600D106.WMF B600D111.WMF The paper end sensor [A] detects when copy paper in the right tray runs out. When there is paper in the tray, the paper pushes up the paper end feeler [B] and causes the actuator to enter the sensor.

Page 750: Stapler
STAPLING 3.5.2 STAPLER Mechanism B602D918.WMF B602D919.WMF B602D920.WMF The stapler/folder motor [A] drives the stapler (! “Action and Drive” in section 3.5.3). Stapler Switch See “Stapler Switch” in section 3.4.3. Sensors There are three sensors inside the stapler: • Staple Home Position Sensor: The staple home position sensor detects the cam position.
Page 751: Positioning
STAPLING 3.5.3 POSITIONING Front Rear B602D921.WMF Action and Drive There is one stapler [A] in the finisher. The stapler is on six rails [C][D][E][I]. The rail [C], rail [D], rail [I], and rail [J] transmit the drive power: • The rail [C] and rail [I] transmit the drive power of the stapler/folder motor. The stapler uses this power to staple the paper (! 3.5.2).
Page 752: Staple Position
STAPLING Staple Position The controller counts the pulses of the stapler slide motor to calculates the distance between the ready position (! Home Position and Ready Position) and the staple position Front-End One Staple 1. Before the stapler slide motor starts, the stapler is in the ready position [C].
Page 753 STAPLING Two Staples 1. Before the stapler slide motor starts, the stapler is in the ready position [G]. 2. The stapler slide motor starts to slide the stapler to the front. The controller counts the pulses of the stapler slide motor.
Page 754: Regular Tray
REGULAR TRAY 3.6 REGULAR TRAY B602D926.WMF Action and Drive The lift motor [I] drives the regular tray to adjust its height. Ready Position Before the stack-tray rollers and belts transport the paper to the regular tray, the lift motor sets the regular tray in the ready position: 1.
Page 755: Paper Sensor
REGULAR TRAY Paper Sensor As illustrated in the previous paragraph (! Ready Position), the paper height sensor [F] can detect either the tray edge or the paper stack. Therefore, the signals from the paper height sensor are not enough to let the controller know if any paper is on the tray.
Page 756: Saddle Stitch
SADDLE STITCH 3.7 SADDLE STITCH 3.7.1 OVERVIEW B602D927.WMF The saddle stitch process consists of the following four phases: 1. The stack tray aligns the paper (!3.7.2). 2. The stapler staples the paper (! 3.7.3). 3. The rollers and the sensor cooperate to transport the paper in the folding position (! 3.7.4).
