4.6 THICK/THIN ORIGINAL MODES
This document feeder has two different ways of stopping originals at the
correct position on the exposure glass. The technician can select one of
these using a copier SP mode. The user can also select the mode.
1. Thick Original Mode (Normal Paper Mode)
This mode is the factory set mode. The belt drive motor remains
energized to carry the original approximately 7 mm pass the left scale
(Figures 1 and 2). Then the motor pauses and reverses to feed the
original back against the left scale (Fig. 3). This forces the original to hit
against the left original scale [A] and thus aligns the trailing edge to
minimize the original skew on the exposure glass.
2. Thin Original Mode
To protect originals from being damaged by the movements of the
transfer belt, thin original mode can be selected. The belt drive motor
stops shortly after the original trailing edge passes the registration
sensor. This stops the original at the correct position on the exposure
glass.
