4.4.12 Surrounding void amount adjustment

The void amount around the network scanned image is adjusted.

around the scanned image due to the subtle difference in the original sizes. This shadow can be

eliminated by adjusting the setting value.

The setting value is applied to all resolutions and color modes.

The procedure is the same as that of  P. 4-15 "4.4.2 Density adjustment".

4.4.13 Judgment threshold adjustment for blank originals (common for

copy and scan)

The adjustment value is simultaneously applied to all modes at PPC and scanning.

The procedure is the same as that of  P. 4-15 "4.4.2 Density adjustment".

4.4.14 JPEG compression level adjustment

The compression level for saving the scanned data in the JPEG format can be adjusted as follows.
