2.3.2 PAPER AND ORIGINAL FEED (B048 ONLY)
NOTE: For clarity’s sake, the following description will refer to the paper’s edges
as edge [A] (furthest edge from the operator) and edge [B] (closest to the
operator).
Original Positioning
In the B048 copier, edge [A] of the original is placed onto the original table. This
activates the original entrance sensor [C].
The main motor turns the original entrance rollers [D]. The quenching lamp,
development bias and PTL also turn on.
For proper feeding (especially for a thin original), the original entrance rollers rotate
backwards (feeding towards the operator) for 300 ms. This ensures that the original
is gripped firmly by both of the original entrance rollers [D], feeding it evenly.
