Hi Steve,
I've seen this with a 3570B, the Cleaning Tape has had over 500(!) mounts,
they've never changed it.
Also, as far as I know the flashing frequence has something to say and also
which indicators flash.
If there's nothing wrong with cleaning please provide me with more
information, I'll then look for the
documentation of those flash's.
Regards
Mecki
