Chapter 2 How to Load 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:
zA5 or larger, A4 or smaller: 20 to 209.3 g/m2 (5.5 to 56.1 lb)
zSmaller than A5, larger than A4: 40.7 to 209.3 g/m2 (11.0 to 56.1 lb)
Friction coefficientWe 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)
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:
Pick Roller
10 mm or less
Document
Bottom of hopper
zWhen 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.
zMultifeed detection by checking the length cannot be used together with [Automatic Page Size Detection].
Use paper sizes that fit the 64 mm width of the pick rollers in the center.
