8. en the top of the stack touches the feed roller the motor cannot pull up the plate any more so it pulls the actuator G into the lift sensor F 2 Detailed Section Descriptions The pressure of the feed roller on the paper is now too high so the lift motor reverses to reduce this pressure reverses for 300 ms or 600 ms depending on the paper size For smaller paper it reverses the larger amount 600 ms to reduce the pressure more 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 20 Paper End Detection Paper End Detection A d331d105 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 When the paper tray is drawn out with no paper in the tray the shape of the paper end feeler causes it to lift up 2 22 2 Detailed Section Descriptions Paper Height Detection d331d956a 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 bot
