I don't happen to have the manual handy, but have the drives
swallowed the tape leader? It's a bit of a pain in the neck to
restring the leader on a DLT7000 compared to a TK50, but it's still
not that hard. When you look in the drive, you should see something
that looks like the bottom end of the following:
