Theory of Operation Ver1.0 Aug.2005
(2) When DF is in use (when DF is closed)
When the start button is turned ON [4], the exposure unit conducts the white correction 1 [5] and the white cor-
rection 2 [6] before moving to the original read position [3]. The same operation is made when AE is selected.
The exposure unit stops at the original read position to read the original [7]. After completion of reading of the
original, the exposure unit conducts the home position search [8] to the position at which the platen APS is read
[1]. And then, it also conducts the home position search [9] to the position at which DF is read [3].
