Control when the Start key is pressed

A. Original scanning mode
Original scanning mode has two types: Original cover mode and DF mode.
(1) Original cover mode
1. Turning the Start key ON will turn the exposure lamp ON (at the standby position).
2. The exposure unit moves in the return direction and stops at the shading position.
At the shading position, the gain adjustment is made.
3. The exposure unit moves in the return direction and stops at the scan start posi-
tion.
4. To start a scan, the exposure unit moves from the scan start position to the leading
edge of an original while performing shading correction. The exposure unit will start
reading the original image from the leading edge. The unit will finish reading the
image at the back edge of the image.
5. The exposure lamp will be OFF when the reading is complete.
6. The exposure unit moves in the return direction and stops at the home position.
Then the exposure unit moves in the scan direction and stops at the standby posi-
tion. It scans only once even for the color-copies, since R, G, and B data will all be
memorized in one scanning.
