Place the print on the exposure glass
in either of the following ways:
• Place an OHP transparency on
the exposure glass, and then
place the print on top of the
OHP transparency.
• Place the print on the expo-
sure glass, and then place two

on top of it. Leave the expo-
sure glass cover or ARDF
open when copying.
