• Maximum Length — select a value that indicates the length of the
longest document in your document set.
NOTES:
- Changing this value will affect the maximums for the following
settings: Image Size - Outline; Printer - Offset From Lead Edge;
Multifeed - Length Detection.
- Not all combinations of settings are supported at the larger
lengths (i.e, resolution, color, grayscale, etc.). To allow for greater
flexibility with applications, the scanner will not generate an error
until it sees a document whose length is not supported.
- The scanner’s throughput may be reduced for larger lengths.
- If a document that is longer than this value is scanned, the
transport will stop (leaving the document in the scanner) and a
document jam message will be displayed.
- The Maximum Length will always range from 2.5 to 180 inches
but the true maximum length of the scan will depend on the bit
depth (color/grayscale/black and white and the resolution used
for the scan). Black and white 200 dpi will be 180 inches, but
color 600 dpi will be much less. If the scanner’s processing
capacity is exceeded before the user-selected Maximum Length
is reached, then a document jam will be posted on the scanner
and the image of the page will not be sent to the host application.
- If scanning a stack of mixed documents, where some of the
documents are very long, the best option may be to select when
to enable Long Document scanning by using either the Single
Document override or Batch override option from the scanner
touchscreen.
- When Controlled Dual Stacking is enabled, the default setting will
be limited to the maximum length of 10 inches/254 mm. See
Chapter 5, “Length Protection Enabled” in the User’s Guide for
more information.
