Conditions for Mixed Batch Scanning
The following conditions apply when scanning a mixed batch
of documents with different paper weights/friction coefficients/
sizes. Always test a few sheets first and see if the documents
can be fed through before scanning a mixed batch of
documents.
For details about scanning, refer to "Documents with Different
Widths" (page 54).
Paper direction
Align the direction of the paper fiber with the feed direction.
Paper weight
For a mixed batch with different paper weight, the following range is
supported for paper weight:
52 to 127 g/m
2
(14 to 34 lb)
Friction coefficient
It is recommended to use the same type of paper from the same
manufacturer.
When papers of different manufacturers/brands are mixed, it affects the
feeding performance as the difference in the friction coefficient
increases.
The recommended friction coefficients are as follows:
0.35 to 0.60 (reference value for paper friction coefficient)
Document position
Make sure to place the documents so that every document in the batch
passes through the 37 mm (1.46 in.) width of the pick roller in the center.
Paper size
When you scan a mixed batch with different sizes, not feeding the
documents straight may cause paper jams or part of the image to
appear missing.
It is recommended to check the documents thoroughly before scanning
and also check the image if the document was skewed.
Documents that cannot be scanned in a mixed batch
The following types of documents cannot be mixed in the same batch:
z Carbonless paper
z Bond paper
z Perforated documents
z Thermal paper
z Carbon-backed paper
z OHP film
z Tracing paper
z Carrier Sheet
37 mm
Pick Rolle
r
z When scanning a mixed batch with different sizes,
documents are more likely to skew because the side guides
do not contact every sheet.
z Do not use [Check Length] or [Check Overlapping and
Length] for multifeed detection.
