Recovery Procedure
If the display shows:
(The stainer does not begin a
cycle when you press RUN).
Make certain the rotor is balanced and that the
carousel is seated correctly on the hub.
Verify keyboard operation by observing the display
while entering slide number settings. The settings
should appear on the display as you press the
intensity keys.
1. Switch the stainer OFF,
2. Wait 10 to 20 seconds,
3. Switch power ON again and try again.
If the problem persists, please contact your
bioMérieux representative.
STAINING
Stain is leaking onto the lab
bench.
Check all external reagent lines for visible signs of
cracks or loose fittings.
Make sure the drain outlet (inside the stainer bowl)
is not blocked by any foreign material.
Make sure the drain tube is securely attached to the
drain port and that the tubing is not cracked or
deformed.
If the problem persists, please contact your
bioMérieux representative.
STAINING
The stainer fails to spray
reagent during a staining cycle
and/or
continues to run after the cycle
should be complete.
To allow programmed staining of partial loads, the
stainer monitors the position of the carousel as it
rotates in the bowl. Stain is sprayed only in the
correct position. This causes the actual cycle time to
vary, depending on the position of the carousel at
the beginning of the cycle.
This is normal stainer operation. However, if the
cycle continues for an abnormally long period, or if
the bar graph and percentage complete icon do not
change after 1 minute, it may indicate an electronic
problem or an internal problem. To determine this,
press the STOP button.
If the cycle stops: this indicates a problem with the
carousel position sensor.
If the cycle continues: this indicates an electronic
problem.
1. Switch the stainer OFF,
2.
Wait 10 to 20 seconds,
3. Switch power ON again
to reset the
instrument.
If the problem persists, please contact your
bioMérieux representative.
