PAPER FEED 20 September 1999 2.8.3 PAPER FEED AND SEPARATION MECHANISM A860D104.WMF The paper feed roller [A] drives the top sheet of paper from the paper tray to the copier. The friction pad [B] allows only one sheet to feed at a time. The friction pad applies pressure to the feed roller with a spring [C].
Page 92: Paper Lift Mechanism
20 September 1999 PAPER FEED 2.8.4 PAPER LIFT MECHANISM A265D521.WMF A265D522.WMF The paper size switch detects when the tray is pushed in. When the paper tray is pushed into the machine, the pin [A] for the lift motor pressure shaft engages the lift motor coupling [B] and the pin [C] for the bottom plate lift shaft in the tray engages the bottom plate pressure lever coupling [D].
Page 93: Paper End Detection
PAPER FEED 20 September 1999 For A4-width paper or wider, a projection [H] on the side fence engages the secondary pressure spring [J] through a lever [I]. Then, the secondary pressure spring [J] applies paper feed pressure in addition to the main pressure spring [K], to ensure that extra pressure is applied to wider paper.
Page 94: Paper Height Detection
20 September 1999 PAPER FEED 2.8.6 PAPER HEIGHT DETECTION A265D522.WMF The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. However, these outputs are only used when the optional printer controller is installed. When the amount of paper decreases, the bottom plate pressure lever [C] moves the actuator up.
Page 95: Feed Pressure Adjustment For Paper Size
PAPER FEED 20 September 1999 2.8.7 FEED PRESSURE ADJUSTMENT FOR PAPER SIZE Overview For the friction pad system, the pressure from the top of the stack against the feed rolleris very important for paper feed quality from the paper tray. If the pressure is high, double feed may occur.
Page 96: Feed Pressure Adjustment
20 September 1999 PAPER FEED Feed Pressure Adjustment The pressure can be adjusted to solve a paper feed problem. This adjusts the amount of lift motor reverse just after the lift sensor is activated when lifting the stack to the paper feed position. To apply less pressure to the top of the stack, the amount of reverse should be increased.
Page 97 PAPER FEED 20 September 1999 From paper near end to paper end When paper is used up, the pressure on the bottom plate reduces, so the upward pressure increases, causing the pressure of the feed roller against the top of the stack to increase.
