Sense key: X'5' (ILLEGAL REQUEST)
(I) Bit per pixel: Byte 1A
Specifies the number of bits per pixel. This value shall be X'Ol', X'04' and X'08' for this scanner. For
an:
value, this scanner returns the following error:
• Status: B'00001' (CHECK CONDITION)
• Sense key: X'5' (ILLEGAL REQUEST)
(m) Halftone pattern: Bytes lB to 1C (lB reserved)
Specifies the dithered pattern used in binarizing multibit multivalued image data. This scanner
validates
this field only with the selection of dither/half-tone monochrome or mixed mode processing. For
other
selections, this field is ignored. The values are specified in the following format:
• Byte IB: Reserved
• Byte IC
7 6 5 4 3 2 1 0
Half-tone pattern number
this bit is reserved
This scanner has four types (X'00' to X'03') of built-in pattern. If a value greater than the four range
is specified, this scanner returns the following error:
• Status: B'00001' (CHECK CONDITION)
• Sense key: X'5' (ILLEGAL REQUEST)
(n) RIF (reverse image format): Byte 1D, bit 7
This scanner does not support RIF. If a value other than X'O' is specified, this scanner returns the
following errors:
• Status: B'00001' (CHECK CONDITION)
• Sense key: X'5' (ILLEGAL REQUEST)
(o) Padding type: Byte 1D, bits 0 to 2
This scanner does not support Padding type. If a value other than X'000' is specified, this scanner
returns
the following error:
• Status: B'0000l' (CHECK CONDITION)
• Sense key: X'5' (ILLEGAL REQUEST)
(p) Bit ordering: Bytes 1E to 1F
