obtained.
Precautions after the completion of the adjustment
• When a non-standard sized original is copied, an area outside the original (or the original cover) may also be
scanned. This may prevent the original size from being accurately detected. If the original cover is soiled, the
type of original cannot be accurately detected. Therefore, instruct the users to clean the original cover on a
routine basis (once a week).
• After the threshold in the Auto color mode is adjusted, based on a particular type of original, other types of
original may not be correctly detected. Therefore, carefully perform the adjustment, while checking whether
any type of original is correctly detected.
