Operation
7.3.1
Control when the Start key is pressed
1.
If the start key is pressed, the scanner starts a shading sequence from the standby
position to shading end position.
If any key but start key is pressed, the scanner starts a pre-shading sequence from
the standby position to shading end position.
2.
After the pre-shading sequence, the scanner is stopped at the return position. After
the lapse of 30 seconds thereafter, the scanner moves to the standby position.
3.
If the start key is pressed in step 1 above or during a period of 30 seconds after the
pre-shading sequence, the scanner starts a scan motion immediately.
4.
After the scan motion has been finished, the scanner makes a return motion to
move back to the return position.
5.
After the completion of the return motion, the scanner starts a home position detec-
tion sequence.
6.
After the home position is detected, the scanner moves to, and stops at, the
standby position.
