M4 9914 tape loading questions

[Brad Parker]

I would clean the entire insides with an alcohol wipe and use a known
good (and hopefully modern tape) the first time.

My cyphers flap the tape around a lot inside as they load but they
eventually suck the tape in and around the takeup reel.

older tapes can sometimes have lots of attraction - sometimes due to
static charge and sometimes due to hydrolyzed binder.  Or both.
