Theory of Operation Ver.2.0 Mar. 2009
B. Operation when the start key is turned ON
For the original read mode, the following two types are available: the platen mode and the DF mode. While in the
platen mode, the exposure unit scans the original for reading. And while in the DF mode, since DF conveys the
original, the exposure unit remains at the prescribed position (DF read position) to read the original.
(1) When the platen is used (when DF is opened)
The operation in the platen mode varies depending on which is selected for the print density, the AE print and
the manual print.
