A build up of oxide on the capstan shaft can cause the tape to ride-up and crease.

Tobacco tar was worse than tape oxide for causing excessive friction.
I clean all the posts, guides drum A/C head etc with IPA, actively avoiding the actual heads on the drum. These then got the paper treatment, a banknote was my preference, applied dry, moderate finger pressure oscillating the drum too and fro with the other hand.
