Problem Possible cause Remedy
The display shows the
"CHECK SLIDES" message
and no specimen slides
are gripped.
1. Low-quality specimen slides
were used.
2. Specimen slides or specimen
slide holders have been damaged
and the instrument cannot detect
them.
1. Use specimen slides that have been manufactured in
accordance with the standard ISO 8037/1.
2. Check specimen slides and specimen slide holders for
damage and replace them if necessary.
The upper part of the tis-
sue samples on the speci-
men slides has dried on.
1. The loading bath is not filled with
sufficient solvent.
2. The loading bath is too low to
cover the tissue section com-
pletely with solvent.
1. Make sure that the loading bath is completely filled
with solvent for "wet" coverslipping. Check the liquid
level and refill if necessary.
2. If the maximum fill level is not enough to cover the
tissue samples completely, the deep loading bath
received in the standard delivery has to be used.
Loading bath, deep – Order No.: 14 0478 39657
Notice! When using the deeper loading bath in work-
stations (Leica ST5010 Autostainer XL or Leica ST5020
Multistainer), take into account that a corresponding
technical modification is necessary when using older
models or upgrading a workstation. Contact the respon-
sible Leica service for this purpose.
The specimen slide hold-
ers do not fit into the bath
insert.
1. The bath inserts or specimen
slide holders are dirty, bent or
inserted into the loading bath
incorrectly.
2. Specimen slide holders from
other manufacturers are used,
which are incompatible with the
bath inserts used.
1. Check whether the bath inserts or specimen slide
holders are correctly inserted in the loading bath. If
necessary, carefully remove any existing dirt or broken
glass.
2. Use bath inserts compatible with the specimen slide
holder ( refer to Chapter 9, Optional Accessories ).
The loading bath does not
move forward; the trans-
port chain does not move.
There is a (mechanical) obstacle in
the transport area.
The transport mechanism consists of a chain module on
the floor of the loading drawer.
Check whether the chains move if the loading drawer is
pulled out. If not, the chains may be blocked, for example,
by glass shards and splinters or dried-on coverslip
mountant. Likewise, check whether there are pieces of
broken glass or specimen slides clinging to the bottom
of the loading bath.
Clean the transport area with a suitable solvent, such
as xylene.
If the chain mechanism does not function even after being
cleaned, contact the responsible Leica Service.
