Stagger Runs on Flow Cell A and Flow Cell B
Possible Run Setup Problems
Problem
Possible Cause
Action
The software did not
initialize.
The software was unable to
initialize internal hardware
devices.
Close the error message and then relaunch the instrument
software.
If the problem persists, restart the instrument computer. If you
are going to restart the computer, first shut down the
instrument to make sure the DoNotEject drive is recognized
correctly.
If the problem persists after restarting the instrument
computer, shut down the instrument, wait a minimum of
60 seconds, and then restart the instrument.
Flow cell lever is orange.
The flow cell did not seat
properly.
The vacuum did not seal.
Manifolds did not raise.
Remove the flow cell and repeat the cleaning steps.
Make sure that the gaskets are present and well-seated.
Reload the flow cell.
If the preceding steps do not work, try replacing the gaskets,
and then reload the flow cell.
Flow cell lever is blinking
orange.
Vacuum is being provided
but is inadequate.
Remove the flow cell and repeat the cleaning steps.
Make sure that the gaskets are present and well-seated.
Reload the flow cell.
If the preceding steps do not work, try replacing the gaskets,
and then reload the flow cell.
Flow cell lever is blinking
green.
Vacuum pressure is good.
Switch flow cell lever to position 2.
Poor fluid delivery.
Potential bubbles in the
system.
Reposition the flow cell and confirm that the holes are facing
down.
Look for white precipitate around the gaskets. If precipitate is
present, replace the gaskets. Always replace gaskets before
an instrument maintenance wash.
Confirm that the sipper assemblies are fully lowered and each
sipper is in contact with the reagents.
Perform a Fluidics Check
Perform a fluidics check during instrument installation and when troubleshooting fluidics issues.
1
Select Check on the Welcome screen.
2
Scan or enter the wash flow cell ID (barcode number) of the priming flow cell. Make sure to use a
used
flow cell for this step.
3
Load the used flow cell onto the instrument.
4
Fill eight SBS bottles with PW1 or laboratory-grade water, and load the bottles onto the SBS reagent
rack.
