(2) Enter adjustment mode [05]. Change the values for code [1675] to adjust the threshold value in the Auto
color mode.
* As the set value is increased, the original will be more likely to be recognized as black-and-white. On the
other hand, if the value is decreased, it will be more likely to be recognized as full color.
Threshold to adjust
Threshold when an original is placed on the
original glass or when the RADF is used
* Set the value in increments of approximately 20, while checking the copy image until the optimum value is
obtained.
Caution after 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.
