. The copier automatically detects the density

of the original, and makes copies at the
optimum exposure.

There are two types of exposure: automatic exposure and manual exposure.
In the automatic exposure mode, the copier automatically detects the density of the original,
and selects the optimum exposure. This mode is suitable for originals containing only text
and illustrations. Originals with black areas and halftoned originals should be copied in the
manual exposure mode.
In the manual exposure mode, you can produce lighter or darker copies.
