5. Scanning-specific Adjustments
Procedures
* You can start with any of the procedures. But it is recommended to perform the procedures in order, as listed
below. You can use 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 used
procedure to the original ones. Then use other procedures.
* Both the service technician and the user can use procedure (1).
* Only the service technician must use procedure (2).
(1) When scanning the original, press the [SCAN SETTING] button on the Control Panel. Press the [+] button
to increase the sharpness intensity.
After increasing the sharpness intensity, scan the original and check the scanned-in image quality.
With the sharpness intensity set to the maximum, if further image quality adjustments are still necessary, the
service technician must use the next procedure.
(2) Enter adjustment mode [05]. Change the values for codes [8335 to 8337 and [7430 to 7433] to adjust the
sharpness intensity.

Precautions after the completion of the adjustment
The adjustment may possibly cause moiré. In addition, when text and thin lines in a light-colored background
are scanned, the background around the text or line may be eliminated. Therefore, carefully perform the
adjustment, while checking the scanned-in image.
