Successful load check
If all of the labware is loaded correctly, the load check ends successfully, and the run starts
automatically.
Failed load check
If the camera discovers one or more errors during the load check procedure, the Load check failed
screen is shown. Incorrect labware placements are marked in red. To get more information about
a particular load check error, tap one of the red positions. A dialog window with details about the
error appears.
Note: All consumable positions should be visually checked to confirm correct placement in
accordance with the instructions detailed in the loading the worktable GUI wizard. Do not
repeatedly rerun a failed load check without first completing this visual inspection. Also, stability of
samples and reagents may be impaired due to extended time on the instrument during repeated
running of the load check.
To return to the loading instructions and start the load check procedure again, tap Back. The Load
the tip rack screen is shown. If you need the instructions from the previous screen, press back again.
Once you have confirmed correct loading of the worktable, tap Next in the Load the tip rack screen.
The Run setup selection overview screen will be displayed where a Skip load check button will now
be available. If you have to correct the loading, the load check must be repeated.
Note: Only use EZ1&2 DSP kits within their expiration date. If an expired kit is used, the EZ2
software will show a warning message. The run/sample is not anymore valid if you use a kit with
an expired shelf life, and accordingly, the run results cannot be used for diagnostic use. This will
be marked as invalid sample in the run report.
Note: In case of repeated load check failure, please recalibrate the camera (refer to Section 6.6).
Contact QIAGEN Technical Support for additional support. During this time samples should be
removed from the worktable and held at appropriate storage conditions.
