a. Dither matrix size
Specifies the size of dither matrix to be downloaded. This scanner supports 8 x 8. If any
other value is specified, this scanner returns the following error information:
• Status: B’00001’ (CHECK CONDITION)
• Sense key: X’5’ (ILLEGAL REQUEST)
b. Dither matrix data
Specifies the values of dither matrix in the range of 0 to 255, starting from the upper- left
corner. (Value 0 represents the darkest, with 255 the brightest.)
The number of data vlaues is the sum of the X- and Y-direction elements as specified in the
matrix size fields. If the number of data values differs from that sum, this scanner returns the
