PARTS GUIDE

[1] PRODUCT OVERVIEW

This model is an externally mounted 3500-sheet paper feeder (large capacity paper feed tray) designed to attach to and work with compatible digital full-color copier products.

It can feed up to 3500 sheets of paper (80 g/m2, 21 lbs), thus allowing the user to handle large copy jobs without having to refill paper frequently.

The paper feeder has an additional separator mechanism that ensures long-term reliable paper feed.

[5] OPERATIONAL DESCRIPTIONS

1. Lift Operation

When the power to the main unit is turned ON with the tray at a midway position (that is, a position where both the upper limit sensor [LUD] and lower limit sensor [LDD] are OFF) or with the tray at the lower limit position (where the lower limit sensor LDD is ON), the main unit issues a lift-up request and, in response, the lift motor is turned ON to lift the tray.

If the Paper-on-tray sensor (LPED) turns ON within 800 encoder pulses of the start of tray lift, the lift motor is temporarily turned OFF to stop the tray, and then the paper feed solenoid is turned ON to lower the pick roller. Subsequently, the lift motor is turned ON, and the tray is lifted to and stopped at a position where the upper limit sensor (LUD) is turned ON.

If the Paper-on-tray sensor (LPED) does NOT turn ON within 800 pulses of the start of tray lift, the paper feed solenoid is turned ON with the lift motor remaining ON, and the pick roller is lowered. The lift motor stops when the tray reaches a position where the upper limit sensor (LUD) is turned ON, and subsequently the paper feed solenoid is turned OFF.

Lift operation is not performed if the power to the main unit is turned ON with the tray at a position where it can feed paper.

When the tray is drawn out, it lowers by its own weight.

Paper feed operation can be performed if the tray is stationary at a position where it can feed paper (with the upper limit sensor [LUD] being ON) and there is paper in the tray.

When paper feed takes place, the transport motor (LPFM), the transport clutch (LTRC), the paper feed clutch (LPFC), and the paper feed solenoid (LPFS) operate with the following timings:

Paper feed time chart (with acceleration)

When the transport clutch (LTRC) turns ON with the transport motor (LPFM) is ON (rotating), the transport roller starts rotating. When the paper feed clutch (LPFC) turns ON in this state, the paper feed and take-up rollers start rotating.

When the paper feed solenoid (LPFS) turns ON, the take-up roller is pushed down to press paper.

Operation stops only if the main unit synchronization signal is output.

When operation is stopped, the ON/OFF timing for each load is delayed by the stoppage time because each timer is suspended during the stoppage.

To ensure efficient job processing, operation is not stopped under normal conditions.

3. Paper-on-tray Detection

The Paper-on-tray sensor (LPED) checks whether there is paper in the tray when the tray is lifted and stopped at a position where it can feed paper, as well as during paper feed operation.

Paper feed operation is stopped if the sensor detects no paper in the tray during paper feed operation.
