Networker (and in fact most backup programs) has no easy way to tell if
a tape is "full" or not, so it simply writes data onto a volume until an
error occurs.  When that happens, the tape is marked 'full'.

If your tapes are not being filled to capacity, that may point to media
errors.  Check the drive (does it need cleaning?), check the connections
from the server to the drives, and check the logs to see if you're
getting any SCSI errors or anything like that around the time when the
volume was last used.
