A condition in which normal changer operation cannot be continued is defined as "error status." When SCSI commands are used for
operations, a check condition is returned to the host computer if an illegal command is sent. However, if normal operation can be
executed by sending a legal command, this is not "error status."
An error with which operation of the disc-carriage mechanism cannot be continued is called a "fatal error." When a fatal error occurs,
the error status cannot be released even if you turn the power off and on again. This is intended to eliminate secondary damage to the
disc or the mechanism caused by starting initialization without removing the cause of the error. Be sure to open the door and check the
internal condition of the changer to find the cause of the error, and take appropriate action. Initialization will start when the door is
closed.
2. Indication and Buzzer upon Error Generation
When an error is generated, the error code and descriptions flash on the display window. The buzzer also sounds in synchronization
with the flashing of the display. When you press any key, the buzzer stops sounding. However, no subsequent operation can be
performed without first operating the lock release key. This means that the operation to release the error can be performed only by the
system administrator who manages the key or by service personnel.
3. Operation Guidance upon Fatal Error Generation
As the door needs to be opened, one-touch shift to Door submode of System-administrator mode is enabled.

When a disc is used in the drive, the drive can be used even if an error occurs in the disc carriage mechanism. However, the door
cannot be opened without stopping the drive. The system administrator should determine which takes priority, error canceling or
continued use of the drive.
• If the host computer is connected, issue a "Rezero Unit" command.
The drive will stop, and the unit will shift to Door submode.
The disc will not be returned.
• If the host computer is not connected, once turn off the power, then
turn it on again.
