The following conditions apply when a mixed batch of documents with different paper weights/friction coefficients/sizes is scanned.

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 with Different Widths.

Paper Type

Align the direction of the paper fiber with the feed direction.

Paper Weight

When scanning documents with different paper weight in the same batch, keep the paper weight within the following range:

• A5 or larger, A4/Letter or smaller: 20 to 209 g/m² (5.4 to 56 lb)

• Smaller than A5, larger than A4: 41 to 209 g/m² (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

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:

ATTENTION

• When scanning a mixed batch of documents with different sizes, skewing is more likely to occur because the hopper side guides do not function on every sheet.

  We recommend scanning with automatic page size detection enabled.

• Multifeed detection with [Check Length] cannot be used together with automatic page size detection.

Combinations of Standard Paper Sizes in a Mixed Batch

Refer to the table below for a guideline of the range available for mixed batch scanning.

DL:	11×17 inches
LTR:	Letter size

ATTENTION

A8 size cannot be scanned in a mixed batch.
