Page 22: Paper Feed And Separation Mechanism
3. Detailed Section Descriptions Paper Feed and Separation Mechanism The paper tray holds 500 sheets. The paper feed roller [A] drives the top sheet of paper from the paper tray to the copier/printer. 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 23: Paper Lift Mechanism
Paper Lift Mechanism Paper Lift Mechanism 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 24 3. Detailed Section Descriptions When the paper tray is pulled out, the pins [A, C] disengage from the couplings [B, D], and the bottom plate drops. To make it easier to push the tray in, the lift motor rotates backwards 1.7 seconds to return the bottom plate pressure lever coupling [D] to the original position.

Page 25: Paper End Detection
Paper End Detection Paper End Detection If there is some paper in the paper tray, the paper stack raises the paper end feeler [A] and the paper end sensor [B] is deactivated. When the paper tray runs out of paper, the paper end feeler drops into the cutout [C] in the tray bottom plate and the paper end sensor is activated. -
Page 26: Paper Height Detection
3. Detailed Section Descriptions Paper Height Detection The amount of paper in the tray is detected by the combination of on/off signals from two paper height sensors [A] and [B]. When the amount of paper decreases, the bottom plate pressure lever [C] moves the actuator up. The following combination of sensor signals is sent to the copier/printer. -
Page 27: Paper Size Detection
Paper Size Detection Paper Size Detection There are three paper size sensors [A] (SN1, SN2 and SN3) on the paper tray unit. Each paper tray has its own actuator [B], with a unique combination of notches. This actuator is moved when the paper end fence [C] is adjusted for the installed paper. - Page 28 3.

Page 29: Side And End Fences
Side and End Fences Side and End Fences Side Fences If the tray is full of paper and it is pushed in strongly, the fences may deform or bend. This may cause the paper to skew or the side-to-side registration to be incorrect. To correct this, each side fence has a stopper [A] attached to it. - Page 30 MEMO...
