PRN-FLG Select of image area flag (PDL image)
Lv.2 Details To set the image area flag for image processing which is performed
when a PDL image fails to be compressed at a specified compression
rate.
If an image fails to be compressed at a specified compression rate,
the following processing is performed by default:
- Processing to prioritize text reproduction
- Replacement of the processed black with single Bk-color
Set 1 when moire occurs or jaggy is significant. Set 2 when not
preferring to replace the processed black with single Bk-color.
Use case - When moire occurs or jaggy is significant in case of printing an image
containing many halftone dots or photos
- When avoiding to replace the processed black with single Bk-color
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Caution This setting trades off with reproducibility of text.

2: High screen ruling, normal LUT
Default value 0
SCN-FLG Select of image area flag (copy image)
Lv.2 Details To set the image area flag for image processing which is performed
when a scanned image fails to be compressed at a specified
compression rate.
If an image fails to be compressed at a specified compression rate,
processing to prioritize reproduction of text is performed by default.
Set 1 when an image contains many halftone photo images. Set 2
when an image contains many printed photos.
Use case When copying an image which contains many halftone dots and
photos
Adj/set/operate method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
