Thank you BOTH for that information. My experience
with TK70 media did not have that happen often enough
that I realized there was a problem. But I will try to
remember to check the rollers next time.
Thank you for your input I'll give it a bit longer.

The metal tape path rollers are used as
tachometers to make sure the
tape is feeding at the correct speed. If the tape drags over them,
the firmware will consider the transport jammed and abort. A drop or
two of light machine oil over the axle has been enough to get the
rollers moving again on my TK50s where this failure mode has occurred.
There are multiple failure domains involved. Lubricating the feed
roller spindles doesn't solve the sticky tape problem.
ok
bear.
We have a winner !!! yes that's what I did.
I had a small bottle of oil that came with my electric razor (Braun
pronounced Brown not Brawn)
It even had a fine nozzle. This is what you do.
Press each roller down (They are sprung) if they do not spring back
up quickly.
then press down again to reveal the top of the shaft.
One tiny drop only where the roller meets the shaft
Do not spin or press the rollers.
Of course it doesn't fix the sticky tape problem.
But it will stop good tapes going in the trash. I have also been trying bulk erasing tapes and
had partial success.
I used a six inch magnet that holds my mobile antenna onto the car.
On INIT it no longer says write protect but it still falls over after
about a minute
I am holding in my hand a cylinder that is about 2 1/2" long
and about 2 3/4" in diameter. It probably weighs about
5 lb.. and if I remember correctly it was the voice coil
from an old speaker that was so badly damaged it no
longer worked. So a permanent magnet needs to be
fairly strong. I suggest that you might try to move your
magnet in a circular motion of about 4" in diameter while
toughing both large sides of the TK70 plastic container.
If you achieve partial success with a minute or two, then
maybe 5 minutes or even 20 minutes might be fully
successful although I would agree that 20 minutes for
every tape is too long. But it would at least prove that
the method works in principle.
