MANUAL
THICKNESS
ADJUSTMENT Especially useful when scanning very thick or very thin papers, this
function enables users to manually specify paper thickness so that
documents may be fed smoothly into the scanner.
For further details on these features, please refer to section 3.3 of the DR-5020/5080C
Instructions manual (“Setting Scan Conditions”).

FIXED THICKNESS
MODE This mode disables the scanner’s automatic paper thickness
detection function; in doing so, it instructs the scanner to use the
paper thickness value established through manual thickness
adjustment (above).
▲
DOUBLE FEED
DETECTION This function memorizes the length and thickness of the first page in
the stack, and compares these values to every other page in the
stack. An error message is displayed when a double feed
(simultaneous feeding of two or more pages) occurs. This function
should be OFF when feeding stacks of various paper types and sizes.
