Status

See Notes 1 and 2

Notes:

1.If the requested transfer volume is more than the actual data volume, this scanner informs the initiator that the requested transfer amount is abnormal. This is done as the scanner returns the status 00001 (CHECK CONDITION) and creates the following sense data:

IL = 1

INFORMATION = requested transfer amount (TL).- actual data amount

This status is usually sent to the last READ command of the sequence. (For commands other than the last READ, the GOOD status is reported.) If the data amount requested by the last READ command agrees with the last data amount left, the GOOD status is reported to the READ command, and the CHECK CONDITION status is reported to the next READ command.

2.Once all scan data has been transferred, the CHECK CONDITION status is always reported to the READ command that follows. Before attempting another read, first issue the SET WINDOW command.
