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 procedure (2).
(1) When scanning the original, press [Scan Setting] on the Control Panel. Press [+] 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 perform the next procedure.
(2) Select [05 ADJUSTMENT MODE]. Change the values for codes [7430 to 7433],[7470], [8335],
[8336], [8354] and [8375] to adjust the sharpness intensity.
• Setting “0” provides the softest image, while setting “255” provides the sharpest image.
Caution after 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.
