tell me about copying thick media
There are a number of factors that affect copying of thick media:
• media thickness positions
• modifying stitching parameters
• treating edge distortion
• supporting thick originals
media thickness positions
Auto-adjustment of the scanner’s light profile, stitching, and so on
only takes place with the insertion slot in the Normal position. With
extended media thickness positions, the last performed auto-
adjustment is stored and utilized. This means that you should from
time to time return to the normal position, and especially when
turning the scanner on, to allow it to auto-adjust.
The Normal position also gives the highest scanning speed. In the
extended media thickness positions, scanning speed is
automatically reduced. See how do I change the insertion slot
height? on page 8.
modifying stitching parameters
Thick stiff originals will rest on top of the scanner rollers and thus
raise a small distance over the glass plate, which will lead to
changes in the stitching of images at points between the cameras
(overlapping pixels). The stitching parameters will need to be
modified in order to correct for this. You can modify stitching
parameters in your application's Scanner Setup dialogs.
treating edge distortion
Scanning thick originals can give distortions when the front edge
meets the exit rollers or the trailing edge leaves the entry rollers. To
omit this, the leading and trailing edges are by default skipped
when in one of the extended media thickness positions.
