Positioning Originals

To position originals accurately, use the guide plate located on the right side of the platen glass.

CAUTION:

Close the platen cover gently to avoid catching your hand, as this may result in personal injury.

•If your original conforms to a standard paper size (e.g., STMT or LTR), align the original between the appropriate paper size marks on the guide plate.

•If you do not know the size of your original, or if your original does not match any of the given paper size

marks, align the center of your original with the ← mark at the center of the guide plate.

Adjusting the Copy Exposure

This copier comes with an automatic exposure control mode. When this mode is set the copier pre-scans the original and automatically adjusts the copy exposure to the most appropriate level. The auto exposure control may not produce clear copies on the following types of originals:

•Originals with a shaded or dark background (e.g., newspapers).

•Light or faint originals (e.g., pencil written work).

Adjustment using exposure recalibration switch

Insert a coin or similar object into the slot in the exposure recalibration switch. This switch has three positions.
