f. ILI (incorrect length indicator) : Byte 2
Indicates that an error in logical block length has been detected
g. Sense key: Byte 2
Indicates the logical unit status using a sense key. This scanner supports the
sense keys shown in the following table:
Sense key Status of logical unit
!!0 NO SENSE
The logical unit has no information to be specifically described in a
sense key. This status occurs because either a command has succeeded,
or because a command has terminated in the CHECK CONDITION
status since the ILI bit has been set to 1.
!!2 NOT READY
The specified logical unit cannot be accessed.
!!3 MEIDUM ERROR
A command has terminated because of a trouble with the medium.
Typical causes of this error with this scanner are that the ADF paper
chute is empty, paper is jammed in the ADF, or the ADF cover has been
opened.
!!4 HARDWARE ERROR
An unrecoverable error was detected.
!!5 ILLEGAL REQUEST
An illegal parameter exists either in a command (CDB), or in a group of
parameters sent in the DATA OUT phase following a command.
!!6 UNIT ATTENTION
The target has been reset.
!!B ABORTED COMMAND
The target has aborted a command.
h. Information bytes: Bytes 3 to 6
The information in this field is effective if ILI is 1. This scanner returns the
remainder (2πs complement for any negative value) so the requested transfer
amount subtracted by the actual transfer amount.
i. Additional sense length: Byte 7
Specifies the number of sense bytes that follows. Even if all additional sense
bytes cannot be tranferred because the allocation length in CDB is small, the
value in this field is not adjusted to indicate the remaining data. This scanner
always assumes X©0Aπ.
