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.

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.
