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 you test a few sheets first to check if the mixed
batch of documents can be fed.
For details, refer to

" Scanning Documents with Different

Widths" (page 85)

.

Paper Direction

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

Paper Weight (Thickness)

The following paper weights can be used:
20 to 413 g/m

2

(5.3 to 110 lb)

Friction Coefficient

It is recommended that the same type of paper from the same
manufacturer should be used.
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)

Document Position

Use paper sizes that fit the 48 mm width of the pick roller in the center.

Paper Size

When you scan a mixed batch with different sizes, 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 documents thoroughly before
scanning and also check the image if the document was skewed.

Documents That Cannot Be Scanned in a Mixed Batch

The following types of documents cannot be mixed in the same batch:

Carbonless paper

Bond paper

Perforated documents

Thermal paper

Carbon-backed paper

OHP film

Tracing paper

Pick Roller

48 mm

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.

When using multifeed detection, select [Check
Overlapping(Ultrasonic)], not [Check Length] or [Check Overlapping
and Length].
