8. Malfunctions and Troubleshooting
Problem Possible cause Remedy
The specimen gets dam-
aged when coverslip
mountant is applied.
The height of the dispenser needle
is set incorrectly or the dispenser
needle was inserted incorrectly.
The height of the dispenser needle is set too low, so that
it scratches the specimen when coverslip mountant is
being applied. The height of the dispenser needle has to
be readjusted to the correct height ( refer to Chapter 4.7 ).
Notice! Make sure the dispenser needle is securely in
place (clamp is in the retaining plate).
The cover slips have been
deposited on the speci-
men slide incorrectly.
1. The cover slip magazine is in-
serted incorrectly.
2. The cover slips stick to each
other.
3. The cover slip sensor is dirty.
1. Check how the coverslip magazine is seated; remove
any dirt or remnants of glass from in/under the coverslip
magazine.
2. Use cover slips of sufficient quality and store them in
a dry place.
3. Check the cover slip sensor for dirt; if necessary, clean
the sensor with a cloth soaked in compatible solvent.
Attention! If the actions described above do not remedy
the problem that has occurred, contact the responsible
Leica Service.
The cover slips have been
deposited on the speci-
men slide at the incorrect
position.
1. The cover slips have been insert-
ed into the coverslip magazine
incorrectly.
2. The parameter CSP has been
selected incorrectly.
1. The cover slips have to be flush against the edge of the
front side in the coverslip magazine.
2. The parameter CSP (coverslip position = cover slip
placement position) has to be corrected. In addition, it
may be necessary to modify the parameter STP (stroke
position = starting point of the coverslip mountant
stroke) ( refer to Chapter 5.10 ).
Intact cover slips are con-
veyed into the cover slip
catch tray.
1. The cover slip sensor is dirty.
2. The suction cups are deformed.
1. Check the cover slip sensor for dirt; if necessary, clean
the sensor with a lint-free cloth soaked in compatible
solvent.
2. Replace the suction cups.
The coverslip mountant
is not evenly distributed.
The dispenser needle is clogged by
dried coverslip mountant or dried
coverslip mountant has accumu-
lated around the dispenser needle.
Replace the dispenser needle with a new one.
Place the clogged dispenser needle in xylene or another,
corresponding solvent overnight and then carefully clean
it of residual mountant.
The Pick & Place module
collides with the coverslip
magazine or there is a
scraping noise when lift-
ing the cover slip.
The cover slip magazine is inserted
incorrectly.
Check whether dirt, such as broken glass, is on the floor
and/or in the holder of the cover slip magazine; if neces-
sary, carefully remove them.
