Document feeder operation (standard model and the M525c model)
The following sections describe the operation of the document feeder for standard model and the
M525c model.
Deskew operation
Sliding-side guides on the input tray make sure that the paper stack is correctly aligned at the center of
the input tray when the tray is loaded with paper. The loaded paper is positioned parallel with the
direction of travel into the document feeder paper path.
Paper skew because of improper loading of paper on the input tray is further reduced by buckling the
paper to create a paper buffer.
The leading edge of the paper is aligned parallel with the deskew drive rollers in before it is driven
further into the document feeder paper path.
The stack-height limiter prevents incorrect insertion of the paper and limits the maximum amount
(stacking height) of media that can be loaded on the input tray.
