(2) When scanning the original, press [Scan Setting] on the Control Panel. Select a higher resolution in
the resolution option.
• “200 (dpi)” is selected from among the resolution options by default. If noise occurs in a resolution
of 200 dpi, select a higher resolution (300 dpi, 400 dpi or 600 dpi).
After changing the resolution, scan the original and check the scanned-in image quality.
If further image quality adjustments are still necessary, perform procedure (1).
(3) Select [05 ADJUSTMENT MODE]. Change the value for the code [8304] to change the JPEG
compression ratio.
Caution after the adjustment
• The adjustment of the compression rate or resolution may possibly increase the size of the file to be
stored. Therefore, carefully perform the adjustment, while checking the scanned-in image quality. The
table below shows you the correlation between a resolution and file size. (The ratio of the file size may
vary depending on the type of original. Therefore, use the table below just for your reference.)
The file size in a resolution of 200 dpi is 1.
• If the resolution selected in procedure (2) is too high, moiré may possibly occur in the scanned-in
image. Therefore, carefully adjust the resolution, while checking the scanned-in image.
Remarks
• Use the following steps to change the default compression rate and resolution options:
(a) Press [User Functions -User-] on [Home] screen to enter the “User Functions” menu.
(b) Press [Scan].
(c) In the “Compress” or “Resolution” option, press the button corresponding to the desired
compression rate or resolution option.
• The default resolution can be selected on a color mode basis: Full color mode (including the Auto
Color mode), Gray scale mode and Black mode.
• The following resolution options are available as the default:
Full color mode (including the Auto Color mode): 600 / 400 / 300 / 200 / 150 / 100 (dpi)
Gray scale mode: 600 / 400 / 300 / 200 / 150 / 100 (dpi)
