Transmits Threshold Level FS ( g pL pH fn m (when fn = 80)
The density of the threshold level of the scanned image for Function 40 is communicated to the
host.
ASCII FS ( g pL pH fn m
Hex 1C 28 67 pL pH fn m
Decimal 28 40 103 pL pH fn m
Range (pL + pH x 256) = 2 (pL =2, pH = 0)
fn = 80
m = 48

The value and transmission data of d3 of Function 40 are as follows:
Setting value -128 … -1 0 1 … 127
Transmission data 128 … 255 0 1 … 127
The transmission data values are converted to hexadecimal characters strings for the image data.
Example: When data is 48 the transmission data will be:
Hexadecimal: 34H, 38H
Decimal: 52, 56
