Making copies

AutoIQ™

The AutoIQ™ feature of the 8825/8830 DDS eliminates the need to make
additional manual adjustments for most input documents.

Automatic adjustment of copy quality

This feature allows the system to dynamically adjust itself for each original.
For example, if the input document is dark, AutoIQ™ will automatically make
the appropriate compensation to optimize the reproduction of the dark
details. If the input document has a faded background, the AutoIQ™ feature
will enable a faithful reproduction of the original with one push of the button.
There are some cases where the user may wish to optimize the settings to
get even better quality output. For example, you may not wish to faithfully
reproduce coffee stains, paste-up lines, or other artifacts on the original. For
this reason, additional controls are available for selection or document type,
document image quality, desired output darkness, and background
suppression.
The AutoIQ™ feature uses information about the document captured during
the staging process. The system automatically adjusts for the darkness of
the background and the image content. Therefore, best results can be
obtained if the document is fed in with an edge that has a representative
sampling of both the background and the foreground image.
Note: always load the side with both background and text or lines first.
AutoIQ™ will use both the white and black information and automatically find
the best settings. This will produce a sharp image and the file size will be
smaller, too.
For the documents that do not have white space on the lead edge (i.e.,
photography or halftone image which covers the whole width), AutoIQ™ may
yield light and inconsistent copies. You can feed a different side that does
have some white space first, or set the Background Suppression selection
to a setting other than Auto.

Automatic edge detection and document centering

The edge detection and auto-centering feature of AutoIQ depends on being
able to distinguish a difference in reflectivity between the document edges
and the white plastic Document Hold-down Guide in the Scanner. For some
documents, this cannot be done, in which case the operator is prompted to
enter the width dimension manually.
The AUTOWIDTH/CENTER feature may be enabled or disabled by the
operator. Refer to the Reference section , Configuration Menu, Scanner
Control , for more information.
Using the AutoIQ™ feature provides an accurate copy for most originals
including Blueline, Blueprints, Color Line Art/Text, and mixed documents
containing combinations of halftone and art or photograph and art. For
documents with inverted images, the INVERT function should be enabled.
Refer to Special features and making special copies – Transform Key for
instructions on the INVERT function.
