 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 [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 use 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.

are scanned, the background around the text or line may be eliminated. Therefore, carefully perform the
adjustment, while checking the scanned-in image.
