Preparing documents
When preparing documents for scanning, keep the following points in mind:
If documents have been stored rolled up, flatten them out. They will be much easier to handle if
they have been stored flat for at least eight hours. The longer that documents have been stored
flat, the easier it will be to scan them. Rolled-up documents will typically roll back up after being
scanned.
If possible, sort the documents you are going to scan according to these guidelines:
•
First, group the documents by media type - bond, vellum or film. Within each
document type, you can further group the documents by image type (e.g., blueprint,
pencil, sepia, line, photo, mixed (photo and line, blueline and pencil), and so forth).
•
Line documents contain lines or text against a highly contrasted background.
•
Photo documents are continuous-tone or grayscale images.
•
Mixed
documents contain both line elements and photo elements or halftone images.
•
Scanning groups of documents of the same type or series (ANSI, ARCH, etc.)
minimizes the number of changes you will need to make to the
Image Quality
settings.
•
Next, divide the documents in each media type group into "good" and "bad" piles
based on your evaluation of their foreground and background quality. See "What is a
good quality document?" and "What is a bad quality document?" in this section for
assistance in doing so.
•
By grouping the documents in this way, you can scan the good quality documents
first. Then you can focus on the bad quality documents, which will require more
attention.
•
Next, determine if any of the documents are inverted (i.e., white or light foreground
against dark background). If any documents are inverted, refer to "Inverting an
image" in the "Special features keys" section.
•
Finally, sort the documents by size or series (ANSI, ARCH, etc.). This minimizes the
number of times you will need to change the

settings when using preset or custom format sizes.
