You'll be 'glad' to know the TZ30 is very informative at this point.

According to the manual you've got a drive problem.

Question, do you still have the tape in the drive? If so can you eject it?
If you try to eject it, and it doesn't want to come out of the drive don't
force it.

If you've got the tape out of the drive check the takeup leader that Tim
mentioned yesterday. The most common problem I've seen with drives that
use this style tape is sucking in the leader. The leader looks something
like this:

-----------------------\ |\
                        \----------| \
                        /----------| /
-----------------------/ |/

Note this is a really horrible representation, but should give you the
basic idea.

For a better idea, I just scanned in a good leader, you can find it at the
following URL ftp://zane.brouhaha.com/pub/ as TK50-Leader.gif.

If you can't get the tape out of the drive, OR if you don't see the leader
you need to pull the drive out of the system. Once you have the drive out,
you'll need to either put the leader back in place, or carefully remove the

If you need to remove the tape, I can offer some more advice.
