Theory of Operation Ver1.0 Aug.2005
B. Operation when the start button is turned ON
The operation when the start button is turned ON varies depending on whether DF is open or closed. In either
operation, the shading correction is carried out first. However, unlike the operation when the power is turned
ON, the exposure unit proceeds to the original read operation with the exposure lamp (L1) left on, and therefore,
the black correction is not conducted.
(1) When the platen is in use (when DF is open)
When the platen is in use and the start button is turned ON, the operation varies depending on whether AE is
selected or not.
• While in the AE copy
When the start button is turned ON [3] while in the AE copy, the exposure unit conducts the white correction 1
[4] and the white correction 2 [5] before the AE scan [6] is made. And then the exposure scan [7] is carried out.
After completion of the exposure scan, the home position search [8] is made.
