Customers can choose the paper transport mode by "User Tool" depending
on the thickness of the original used.
– In thin paper mode –
The belt motor stops exactly when the trailing edge of the original passes the
right scale [A] edge. (The timing is measured by the timing sensor after
registration sensor is activated.)
– In thick paper mode –
To correct skewing on the exposure glass, the original runs 10 mm after the
trailing edge passes the right scale. The belt motor then reverses and the
original travels until it meets the right scale.
If extremely thin paper is used in the thick paper mode, the paper may float
near the scale. This will result in poor image quality or original copy wrinkling.
The factory setting is "Thin Paper Mode".
