Rewinding a Tape
the drive while a tape is being read and power cannot be restored, the cartridge must
be removed by a trained service provider.
Rewinding a Tape
The tape drive automatically rewinds the tape before unloading a cartridge. Typically
an application program sends commands to rewind the tape and unload the cartridge
at the end of a job. However, occasionally you might need to rewind and unload a tape
manually.
The following procedures assume that a cartridge is loaded in the tape drive and that
the tape position is past BOT.
Rewinding Tape Without Unloading the Cartridge
Use this procedure to rewind a cartridge tape without unloading:
1. Press the RESET button. The message panel shows NT RDYU or NT RDYF.
2. Press the START button. During rewinding, the message panel shows
REWINDNG.
3. If you receive an error message, see Responding to Error Messages and Check
Codes on page 4-31.
Rewinding Tape and Unloading the Cartridge
Use this procedure to rewind and unload a cartridge tape:
1. Press the RESET button. The message panel shows NT RDYU or NT RDYF.
2. Press the UNLOAD button to eject the cartridge. During unloading, the message
UNLOADNG appears on the message panel. If the tape needs rewinding, the
drive automatically begins rewinding the tape and the message REWINDNG
appears on the message panel. It should take no more than two minutes to
rewind.
3. If you receive an error message, see Responding to Error Messages and Check
Codes on page 4-31.
Caution. Do not pull a cartridge out of the drive if it's stuck. Doing so could damage the tape
or the tape-reading mechanism.
