Conditions for Mixed Batch Scanning
The following conditions apply when a mixed batch of documents with different paper weights/
friction coefficients/sizes is scanned.
Make sure to test a few sheets first to check if the mixed batch of documents can be fed.
For details about scanning, refer to
Scanning Documents with Different Widths (page 107) .
Paper Direction
Align the direction of the paper fiber with the feed direction.
Paper Weight (Thickness)
When scanning documents with different paper weight in the same batch, keep the paper
weight within the following range:
40 to 209 g/m 2 (11 to 56 lb)
Friction Coefficient
It is recommended that the same paper brand from the same manufacturer is used for
documents.
When different paper manufacturers/brands are mixed in documents to be scanned, it affects
the feeding performance as the difference in friction coefficient increases.
The following friction coefficients are recommended:
0.35 to 0.60 (reference value for paper friction coefficient)
Document Position
Load all documents covering the width of the pick roller (approx. 39 mm/1.54 in. wide).
