Basic Scanning Procedure
When the scanner receives the ADF scanning command, the scanner scans the
original as described below.
1) ADF Mode
The scanner performs the home position check and the shading process. If a home
position error is detected, the scanner [K] will stop immediately. If an ADF cover
open error or memory error is detected, the scanner will stop after returning to the
home position.
The first carriage moves to the ADF scanning position [J] from the scanner home
position [I]. Then the paper transport motor starts.
2) SADF Mode
The scanner waits until the designated time for the originals to be placed on the
document table [A].
When the originals have been placed on the document table, the same procedure
as for ADF mode is carried out.
