Explanation Sets the threshold value to read, using two values.
The threshold value settings are as follows:
Setting value
The threshold value set with the pre-scanning has priority when
pre-scanning is executed before executing the EndInsertion method.
The default value is "0".
The settings with this command are effective only for check scanner
mode. Although during card scanner mode, a threshold value can be
set by executing this command, the settings are not reflected to card
reading directly. If these settings are set during card scanner mode,
the settings become effective after changing the mode to check scanner
mode, and only for reading checks.
When the CHK_DI_SHARPNESS_IMAGE command of DirectIO method
is set, the set value with this command is not reflected to the read
images.
