Original Feed Speed - Ricoh D124 Detailed Descriptions Manual

2.4.2 ORIGINAL FEED SPEED

In the diagram above, the red numbers (%) below the horizontal axis of both graphs
show the magnification steps for copy jobs. The green numbers (dpi) below the
horizontal axis of both graphs show the resolution steps for scanning jobs.
During copying, the speed of original feed is adjusted for magnification (resolution is
fixed at 600 dpi). During scanning to a file, the speed of original feed is adjusted for
resolution (magnification is fixed at 100%).
The scanning speed increases as resolution or magnification lowers. But to prevent
color separation caused by excessive speed, scanning speed does not increase any
more when resolution (or magnification) reaches the following values, and then image
processing reduces the data:
 Black-and-white: When resolution is less than 300 dpi or less, or magnification is
less than 50% [A]
 Full color: When resolution is less than 400 dpi or less, or magnification is less
than 66% [B]
