• When "High Compression for Color PDF" is selected, characters and

backgrounds on the document are compressed separately. In order to do this,

the file size of the document that mostly consists of text characters becomes

smaller while keeping the quality of the characters as they are. However, this

mode is not appropriate for scanning photographs or pictures since these

graphical materials are recognized as background and compressed as such,

causing degradation in the scanned image. If this setting is specified, the

contrast of the image may become higher.

• When one color page is scanned, the file size criteria are shown as follows.

These numbers are for reference, other documents may vary in size.

Actual paper size: A4 size (general catalog)
