Feed Pressure Adjustment; Effect Of The Amount Of Remaining Paper - Gestetner A265 Service Manual

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.

The pressure between the top of the stack and the fed roller also depends on the
amount of remaining paper, especially for small paper sizes, as shown in the above
graph. The pressure for A5 changes significantly between stack heights of 500
sheets and 50 sheets, but not much for A4 or A3 paper.
For 500 sheets of A5, the pressure is too high. To counter this, the lift motor
reverses 600 ms (
