In addition, the threshold can be changed by adjusting the image area to be used for the judgment, too.
Perform this adjustment if an original whose judgment target image is located on the edge of the paper is
used.
Procedures
• You can start with any of the procedures. But it is recommended to perform the procedures in order, as
listed below. You can perform one procedure in conjunction with another. But if this changes the image
quality more than required or loses the effectiveness of the adjustment, restore the settings made in
the previously performed procedure to the original ones. Then perform other procedures.
• Both the service technician and the user can perform procedure (1).
• Only the service technician must perform procedures (2) and (3).
(1) Change the threshold for the Auto Color mode.
Follow steps (a) through (c) to perform the adjustment.
(a) Press [User Functions -User-] on [Home] screen to enter the “User Functions” menu.
(b) Press [Copy].
(c) Change the threshold with the “ACS Adjustment” indicator. If you move the indicator to the left,
the original tends to be judged as a black original. If you move it to the right, the original tends to
be judged as a color original.
<Hint>
• The relation between the position of the “ACS Adjustment” indicator and the judgment result is
shown below. In the actual adjustment, the threshold varies depending on the shape and size of
the original or the density level of the original image. Therefore use the table below only as a
reference.
• Position of indicator: “0” in the table above denotes the left end of the indicator (the original is
judged as black most) and “6” denotes the right end of the indicator (the original is judged as color
most).
• Adjustment value: This refers to the judgment threshold for the Auto Color mode. The adjustment
value of the code in step (2) below will be added to this value.
• The diameter of the standard “stamp” is approx. from 8 mm to 12 mm. In this field the number of
the stamps on the chart and its judgment result are described.
• The size of the standard “red character” is approx. 10.5 pt. In this field the number of the red
characters entered and its judgment result are described.
After specifying the original size and copy size, copy and check the copy image quality. If further image
quality adjustments are still necessary, the service technician must perform the next procedure.
