Scanning a Mixed Batch of Documents
The following restrictions apply when scanning a mixed batch
of documents with different paper thicknesses/friction
coefficients/sizes. Always test scan a few sheets and see if the
documents can be fed through before scanning a mixed batch
of documents.
For information on how to scan mixed batches, refer to
"Scanning Documents of Different Widths" (page 86).
Paper type
Align the direction of the paper fiber with the feeding direction.
Paper weight
When scanning documents with different paper weight in the same
batch, keep the paper weight within the following range:
z A5 or larger, A4 or smaller: 20 to 209.3 g/m
2
(5.5 to 56.1 lb)
z Smaller than A5, larger than A4: 40.7 to 209.3 g/m
2
(11.0 to 56.1 lb)
Friction coefficient
We recommend that you 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
Use paper sizes that fit the 64 mm width of the pick rollers in the center.
Paper size
When a set of wider documents is placed on top of smaller documents
within the same batch, the wider documents on top may hang down and
affect the feeding performance.
Try to meet the following condition:
64mm
Pick Roller
z When scanning a mixed batch of documents with different
sizes, it is more likely to skew because the hopper side
guides do not function on every sheet. We recommend
scanning with [Automatic Page Size Detection] enabled.
z Multifeed detection by checking the length cannot be used
together with [Automatic Page Size Detection].
Pick Roller
10 mm or less
