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.

Paper Direction

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

Paper Weight (Thickness)

Documents with the following paper weights can be scanned when scanning a mixed batch of documents with different paper weights:

27 to 413 g/m2 (7.2 to 110 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.

For a guideline for mixed batch scanning, refer to Combinations of Standard Paper Sizes in a Mixed Batch in Paper Size.

Width of the Pick Roller
Document Position
HINT

When the smallest document covers the width of the pick roller even when it is loaded towards one side as shown in the image below, load documents aligned on one side. So that it prevents documents from skewing when being fed.

Document Position
Paper Size

When a mixed batch with different sizes is scanned, not feeding the documents straight may cause troubles such as paper jams or part of the image to appear missing.

It is recommended that you check the scanned images if the documents were fed skewed.

ATTENTION

  • When a mixed batch with different sizes is scanned, documents are more likely to skew because the side guides do not contact every sheet.

  • Do not specify the detection method by document length when scanning a mixed batch of documents with different lengths and detecting overlapped documents.
