Help,
My Quantum DL4000 or DEC TZ88 has come undone...
IOW, the leader which snares the tape has come loose, and I don't know
how to wind it back... :-{
The mechanism has 6 heads; I tried to wind it around the 6-headed
path, but the leader is not long enough, so it must be wound around a
shorter path...but which one??
It's OK it nobody's understand what I'm talking about :-), as long as
someone is kind enough to post naked pics of a working TZ87/88 of how
the leader is being wound.
TIA.

The TZ88 doesn't have 6 heads, it has 6 guide rollers and 1 head. The pickup
leader must hook on the plastic tab at the back of the cartridge bay and
wind round all 6 guides before it hooks onto the takeup spool at the back of
the drive. If it's not long enough then it's snapped. If nobody else has a
drive easily to hand to dismantle I can get one off the shelf at work - part
of my job is repairing these things :)

How is it wound? Going anticlockwise from the takeup spool:
Roller1: outer circumference
Roller2: outer circumference
Roller3: outer circumference
Roller4: outer circumference
Roller5: inner or outer circumference?
Roller6: inner or outer circumference?

Great!! Please take some pics...
p.s. How the heck do you dismantle the plastic which covers the cartridge?

I'm not sure if the drives are ontopic, but if they're not they're very
close. I first saw one about 8 1/2 years ago.
It's been a few years since I had to restring a DLT4000, but as I recall it
isn't that much different than a TK50.
In any case I think you can probably find the info you need on the Quantum
website.

is the leader still attached to the plastic spool near the back of the
drive? You can unhook the clear plastic cover over the spool from its many
catches / latches and carefully remove it, and turn the spool until you can
see the end of the leader. Does it have a hook attached to it, in the form
of a plastic cap with a hole in it? If all you have at the end of it is a
ragged end, you need a new leader.
Information wants to be free!

Thanks to everyone who had answered..
I finally figured out how to wind the beastie, and in the process
learnt how the tape-leader interaction can be so precariously based on
luck.. :-)
It is so astounding that for the tape noose from the cartridge to be
extended just so a couple of millimeters enough for the leader head to
snag it and for the hook to be retracted all at the same time. *wow*
Needless to say I spent many minutes watching the whole thing while
it's doing its jig.. :-)

I understand that you just got it, congratulations!
Here are three steps that might have helped you.
Push the leader-holder springlever back.
Hook the leader in the pushed back position.
Allow spring lever to return forward.
Have fun,
John A.
