media offset Select the Media Offsets button 1. To get very high accuracy, modify the vertical precision from zero to a value between -1% and 1%. Positive settings mean that the distance between scan lines will be increased, and negative settings mean that the distance between scan lines will be decreased. When you exit the Scanner Setup dialog, the modified value is stored in non-volatile memory in the scanner and can only be changed by re-doing the setup. 1. Paper offset -/ Top, Side, Bottom The Paper Offset values determine the position of the scan area. You can use the option to adjust the capture area's position. This is done by moving the area to the right and down. Top media offset: Move the area up or down. Perhaps there are details close to the top edge that you want included or excluded in the scan. Bottom media offset : Move the scan area bottom marker up or down. Perhaps there are details close to the bottom edge that you want included or excluded in the scan or you wish to fineadjust the scanner's calculation of size length. Side media offset: Move the area to the left to include/exclude details close to the original's left edge. extended thickness (stitching offsets) Stitching is the scanner's automatic control of boundaries between the cameras and creation of correct overlap of image data. Stitching errors can happen when the original is not evenly pressed down on the scanner's glass plate . The most common case involving stitching errors is when scanning stiff thick originals with the pressure platen raised for thick-original scanning . NOTE: The extended thickness settings apply only with the HP HD Pro Scanner Normally, only stiff media will affect stitching. A flexible media will usually be stitched correctly regardless of its thickness.

1. To get very high accuracy, modify the vertical precision from
zero to a value between -1% and 1%.
Positive settings mean that the distance between scan lines will be
increased, and negative settings mean that the distance between
scan lines will be decreased.
When you exit the Scanner Setup dialog, the modified value is stored
in non-volatile memory in the scanner and can only be changed by
re-doing the setup.
1. Paper offset -/ Top, Side, Bottom
The Paper Offset values determine the position of the scan
area. You can use the option to adjust the capture area's
position. This is done by moving the area to the right and down.
Top media offset
: Move the area up or down. Perhaps there are
details close to the top edge that you want included or excluded
in the scan.
Bottom media offset
: Move the scan area bottom marker up or
down. Perhaps there are details close to the bottom edge that
you want included or excluded in the scan or you wish to fine-
adjust the scanner's calculation of size length.
Side media offset
: Move the area to the left to include/exclude
details close to the original's left edge.
extended thickness (stitching offsets)
Stitching is the scanner's automatic control of boundaries between
the cameras and creation of correct overlap of image data. Stitching
errors can happen when the original is not evenly pressed down on
the scanner's glass plate . The most common case involving stitching
errors is when scanning stiff thick originals with the pressure platen
raised for thick-original scanning .
NOTE
: The extended thickness settings apply only with the HP HD
Pro Scanner
Normally, only stiff media will affect stitching. A flexible media will
usually be stitched correctly regardless of its thickness.
