Chapter 2 How to Load Documents
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/m2 (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)
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.
zWhen scanning a mixed batch with different sizes,
！documents are more likely to skew because the side guides do not contact every sheet.
zDo not use [Check Length] or [Check Overlapping and Length] for multifeed detection.
Documents that cannot be scanned in a mixed batch
The following types of documents cannot be mixed in the same batch:
zCarbonless paper
zBond paper
zPerforated documents
zThermal paper
z
zOHP film
zTracing paper
zCarrier Sheet
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.
