5. Scanning-specific Adjustments

5.1

To Clearly Scan Text (To reduce noise around text)

Before adjustment
If the original is scanned in the Full color
mode or the Image Smoothing mode,
noise may occur in text or edges of a solid
filled area.
 Explanation
When an original is scanned in the Full color or the Gray scale mode, the data compression may cause
noise (toner scattering) around text or the edges of a solid filled area. Adjust the compression rate or
change the scan resolution, in order to obtain a better scanned-in image, while reducing noise.
• This adjustment will have an effect on the image scanned in the Full color mode (including the Auto
Color mode) or the Gray scale mode.
 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 this procedure. However, step (3) in the
procedure must be performed only by the service technician.
(1) When scanning the original, press [Scan Setting] on the Control Panel. Select "Low" from among the
compression rate options.
• "Mid" is selected from among the compression rate options by default.
After changing the compression rate, scan the original and check the scanned-in image quality.
If further image quality adjustments are still necessary, perform procedure (2).

After adjustment
The image quality is maintained, while
noise is being reduced.
