Serial Cmd: <K708,symbol quality separator,output mode>

Default: Grade

Options: 0 = Grade 1 = Value

Usage: Lets the user know if contrast settings are less than acceptable.

Definition:

All the pixels that fall within the area of the test symbol, including its

required zone, will be sorted by their reflectance values to select the dark-

est 10% and the lightest 10% of the pixels. The arithmetic mean of the dark-

est and the lightest pixels is calculated and the difference of the two means

is the Symbol Contrast.

(ANSI) Symbol Contrast grade is defined in this way:

A (4.0) if SC > 70% B (3.0) if SC > 55%

C (2.0) if SC > 40% D (1.0) if SC > 20%

F (0.0) if SC < 20%

If enabled, the symbol contrast is appended to the symbol data according to

the ISO/IEC 15415 Symbol Quality Output Mode setting.

Serial Cmd: <K709,symbol contrast,print growth,axial non-uniformity,unused ecc>

Default: Disabled

Options: 0 = Disabled 1 = Enabled
