Clogs
Often, a clog somewhere in the Luminex
®
FLEXMAP 3D
®
instrument is the cause of a fluid
leak, a pressurization or sample probe problem, or a problem with calibration, verification, or
data acquisition.
To determine whether there is a clog, check the bead count during calibration. During
calibration you should see 300 bead events per second or more. If there are fewer than that,
there is probably a clog in the instrument.
In the event you encounter a problem that is clog-related, use the following procedure.
To troubleshoot a possible clog:
1. Clean and adjust the sample probe. See the section titled “
Cleaning the Sample Probe
”.
2. Perform the procedure for removing clogs. See the section titled “
”.
3. Replace all fluids.
4. Use the software to run the weekly maintenance routine.
5. Run calibration and verification.
If this procedure is unsuccessful, call Luminex Technical Support.
Pressurization Problems
Normal air and sheath pressure readings vary between 8 and 13 psi while the compressor
runs. If the instrument pressure is out of range, sample acquisition either can fail or can
return inadequate results.

Pressurization Problems
Symptom
Possible cause
Solution
Pressurization fails or pressure is
too low.
The sheath and waste lines are not fully
connected.
Check the lines between the sheath and
waste bottles and theLuminex

instrument.
The sheath or waste fittings are cracked.
Inspect the fittings to be sure they form a
tight seal. If not, call Technical Support.
There is a leak in the instrument.
Check for leaks. A leak is obvious if there
is fluid on the surface where the FLEXMAP
3D instrument sits. See the section titled
“
”.
The compressor does not engage.
Use the software to run a prime command.
If you do not hear the compressor turn on,
contact Technical Support.
