To Clearly Scan And Print An Original In Black And White (To Improve Gradation And Reduce Graininess) - Toshiba e-Studio6506AC Imaging Manual

5.3 To Clearly Scan and Print an Original in Black and White
(To improve gradation and reduce graininess)
Before adjustment
If the original is scanned in the Black mode,
the halftones may become blurred in black.
 Explanation
If an original is scanned in the Black mode, a difference in the density level of the halftones cannot be accurately
scanned. As a result, it may become blurred in black or grained. Scan a black-and-white original in the Gray
scale mode, in order to scan and print it out in black and white more clearly.
 Procedures
* Both the service technician and the user can perform all adjustments.
(1) When scanning the original, press [SCAN SETTING] on the Control Panel. Select "GRAY SCALE" from
among the color mode options.
 Caution after the adjustment
The adjustment may possibly increase the size of the file to be stored. Therefore, carefully perform the
adjustment, while checking the scanned-in image quality. The correlation between color mode and file size is as
described below. (The ratio of the file size may vary depending on the type of original. Therefore, use the
description below just for your reference.)
* Ratio of the file size in the Black mode to the Gray scale mode
• If the file size in the Black mode with the Text mode selected is 1, it will be increased to approximately 7 times
in the Gray scale mode.
• If the file size in the Black mode with the Photo mode selected is 1, it will be approximately doubled in the
Gray scale mode.
