7.8 Scanning Mixed Documents
7.8 Scanning Mixed Documents
When scanning documents of different thickness/Friction Coefficients/sizes using this scanner, the follow-
ing restrictions apply. Before you scan any mixed documents, always test scan a few pages to see if the
mixed document can be properly fed.
(For details on how to scanning mixed documents, refer to “3.3 Scanning Documents with different
widths” on page 73.)
■ Types of Documents
It is recommended to align the paper direction (how the fibers are lying in the sheet) with the feeding direc-
tion.
■ The Thickness of Documents
The mixed documents’ paper weight (thickness) should be in the range below:
31 ~ 209.3g/m
2
(8.3 ~ 56.1lb; 0.038 ~ 0.257mm)
For paper sizes equal or bigger than B4: 52 ~ 157 g/m
2
(14 ~ 42 lb)
■ The Friction Coefficients
Paper of same manufacturer’s same brand is recommended. When paper of different manufactuerers/
brands are mixed, the differences of their friction coefficients become very large, which will adversely
affecting the feeding performance.
Generally speaking, the friction coefficients of different kinds of paper shall be in the range of 0.35 - 0.60.
■ Document Sizes
Refer to the table below when mixing documents of different sizes.
ATTENTION
• When scanning mixed size document, because the hopper side guides
will not function, the scanned images are easily skewed.
We recommend you to enable “Automatic Page Size Detection”.
• Multifeed Detection by length cannot be used together with “Automatic
Page Size Detection”.
