Perfect Page with
iThresholding Perfect Page with iThresholding is essential when you are scanning
mixed batches of documents of varied contrast in background and/or text.
Brightness is automatically adjusted for each individual document for
highlighting, low contrast, and lightweight paper — situations that previously
required manual adjustments.
Using the iThresholding feature, the scanner dynamically evaluates each
document in the batch to determine the optimal threshold value to produce the
highest quality image.
The iThresholding feature delivers high-quality images from a large range of
both poor- and high-contrast documents and reduces the need to pre-sort,
rescan, and perform post-image processing. You get better image and text
legibility, smoother lines, minimal to no artifacts, and fewer shaded areas with
minimal or no user intervention.
Toggle patch The Toggle patch triggers the scanner to switch from the current scanning
mode to the alternative mode (i.e., bi-tonal to color or color to bi-tonal).
When you scan using a Toggle patch (shown at right),
color on-the-fly processing is enabled. With color on-the-
fly, scanning automatically switches between scanning
modes whenever a Toggle patch is read by the scanner.
NOTES: The Toggle patch document is available as a
.pdf file on the Installation CD. Print the Toggle
patch document on a good-quality printer.
Do not scan a duplex Toggle patch document
(where the Toggle patch printed on both sides)
in duplex mode.
