a. Data type code: Byte 2
Specifies the type of data to be transferred between the initiator and target.
This scanner supports X©00π (image data), X©80π (pixel size), and X©81π
(detected paper information) only. If any other value is specified, this scanner
returns the following error information:
f Status: B©00001π (CHECK CONDITION)
f Sense key: X©5π (ILLEGAL REQUEST)
b. Data type qualifier: Bytes 4 to 5
This scanner requires specifying byte 4 = X©00π and byte 5 = window
identifier. If the window identifier specified in byte 5 has not been declared by
the DEFINE WINDOW PARAMETERS command, this scanner returns the
following error information:
f Status: B©00001π (CHECK CONDITION)
f Sense key: X©5π (ILLEGAL REQUEST)
c. Transfer length (TL) : Bytes 6 to 8
Specifies the bytes of storage area that the initiator has allocated for the data to
be transferred.
If TL = 0, no data is transferred. This is not assumed an error.
The target does not transfer more data than that which is indicated by TL.
