Original Width Detection Failure
There is no original width sensor.
The CCD detects the width of the paper before scanning
(this is known as ‘pre-scanning’).
If the original has punch holes, or is thin or transparent, the
CCD may detect the incorrect width.
The following problem may occur for thin originals:
If the user opens the cover during pre-scanning, they may
get a strong light from the scanner lamp in their eyes.
To prevent this, the lamp power is less during pre-scanning
(default: 60%).
However, with the reduced setting, sometimes the machine
cannot detect the original size.
If this happens, increase the setting using SP4-309-004.
