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. Make sure to test a few sheets first to check if the documents can be scanned.
For details about scanning, refer to "Documents with Different Widths" (page 69).
Paper direction
Align the direction of the paper fiber with the feed direction.
Paper weight
The following paper weights can be used: 41 to 209 g/m² (11 to 56 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 following friction coefficients are recommended:
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
Document position
Use paper sizes that fit the 39 mm width of the pick roller in the center.
