Detailed Section Descriptions SM 15 B792 B792 Finisher 2.2 DETAILED SECTION DESCRIPTIONS 2.2.1 OUTPUT TRAY MECHANISM Stack Height Detection Stack height detection lever [A]: Driven by stack height lever solenoid [B]. Two sensors detect the height of the stack in the output tray: the stack height [C] and lever [D] sensors. Stack height sensor Lever sensor Status Off Off The stack height is below the target. The output tray is then lifted to the target position. Off On Target stack height position On On The stack height is above the target. The output tray is then lowered to the target position. On Off The stack height detection lever is at home position. Off: Actuator not in sensor At the start of a print job, the solenoid turns off. The stack height detection lever comes down, to detect the current stack level. When a sheet of paper is being fed out, the solenoid turns on and the lever goes back up to home position (inside the unit). After paper has been fed out, the solenoid turns on again, and the lever detects the level of the stack.
Detailed Section Descriptions B792 16 SM Output Tray Up/Down Mechanism Overview The output tray motor gear [A] lifts/lowers the tray if the stack height is not at the target position. Gears [B] and [C] keep the angle of the tray constant at any tray position. Output Tray Downward Movement The top of the paper stack is checked after every page (or set of pages) has been fed out. If the top of the stack is higher than the target level, the output tray motor moves the tray down. When the stack near-limit sensor [D] detects the actuator on gear [C], a stack near-limit signal is transferred to the main frame. The tray cannot move any lower. The next time the top of the stack height is above the target level, printing stops. Output Tray Upward Movement If paper is removed from the stack, the top of the stack will be lower than the target level, and the output tray motor moves the tray up. When the tray upper limit sensor [E] detects the actuator on gear [B], the tray cannot be moved up any more, so the motor stops.
Detailed Section Descriptions SM 17 B792 B792 Finisher 2.2.2 PAPER FEED When a sheet of paper is fed, it is transported through the 500-sheet finisher as shown in these drawings. To feed paper straight through the finisher, the pick-up roller [A] stays up. To send the paper to the jogger tray [B], when the trailing edge is almost out of the finisher, the pick-up roller moves down until the reverse/exit roller in the pick-up roller pushes the paper against the paddle roller [C]. The reverse/exit roller feeds the paper to the jogger tray. The pick-up roller is lifted up and down by the pick-up roller contact motor. The pick-up roller feeds the paper out after stapling, sorting, or stacking. The reverse/exit motor controls the reverse/exit motor. The other rollers do not change direction, and are controlled by the paper transport motor.
Detailed Section Descriptions B792 18 SM 2.2.3 JOGGER MOVEMENT The jogger tray unit consists of the front [A] and rear [B] jogger fences, two jogger motors [C] and two jogger fence HP sensors [D]. Standby mode: The jogger fences are placed at home position. Sort mode: The joggers move alternate sets to the front and rear, to separate the sets for the users. At the start of the job, the jogger fences move to the front and rear sides. When the first set of the job is fed to the jogger tray, the front jogger fence moves towards the rear to stack the paper neatly. When the second set of the job is fed, the rear jogger fence moves towards the front to stack the paper neatly. The front and rear fences continue to operate like this for alternate sets, until the end of the job. Staple mode: Only the front jogger fence moves in staple mode.
