In the following table there is a list of the most common problems which can arise while
working with the instrument, along with possible causes and troubleshooting procedures.
8. Troubleshooting
Problem Corrective action Possible cause
1. Thick/thin sections
The sections alternate between
being thick and thin, or there is
chattering in the sections, or
the specimen is torn out of the
embedding. In extreme cases,
there are no sections whatso-
ever.
• Reclamp the blade, knife holder
or orientation.
• Blade, knife holder or orienta-
tion is not clamped properly.
• Check that the cassette is securely
clamped in the universal cassette
clamp.
• If the universal cassette clamp is
soiled by wax, clean the UCC (refer to
Chapter 8.1 – "Cleaning and mainte-
nance – Universal Cassette Clamp").
• When using cassettes whose lid is
molded on, check that the broken
edge allows the cassette to be
clamped securely; if necessary,
remove burrs or clamp the cassette
into the universal cassette clamp
horizontally instead of vertically.
• If the cassette dimensions are within
the specified tolerances and the cas-
sette still cannot be securely clamped
into place, it may be that the universal
cassette clamp is configured incor-
rectly or is defective. In this case,
have Technical Service inspect and
reconfigure the universal cassette
clamp.
• When using cassettes, particularly
thin-walled cassettes, from a com-
pany other than Leica or Surgipath,
the cassette may become deformed
or other clamping problems may
arise.
If while trying to clamp the cassette
you realize that it is not securely
clamped into place, an alternative
tensioning clamp must be used.
• The specimen is not clamped
properly.
