blade. If using a stainless steel or tungsten-
carbide knife, sharpen the knife.
There is dirt on the Tape
Use a fresh, clean and cold Tape.

There is vibration in the microtome (thick/thin,
chatter, etc.)
Check the knife and block for looseness and
tighten all screws and clamps as needed.

Cause
Solution
The mylar film on the Slide has not been
removed.
