9.2 Error messages
You can exit device displays with error messages using the [OK] softkey.
System errors require an evaluation by the Technical Service. These errors are shown in English (System
error …). Please contact Technical Service in these cases. Other error messages, for which you can carry
out troubleshooting measures, are illustrated in the table below.
Problem Cause Solution
Self test failed. • Cuvette shaft cover was open
during self test.
• The cuvette shaft was not empty
during the self test.
 Repeat the self test with empty
cuvette shaft and the cuvette shaft
cover closed.
• Device is faulty.  Contact Eppendorf Service.
File export failed. During data export:
• USB stick improperly formatted or
faulty.
• USB stick removed from the device
too early (during the export).
 Reformat or replace the USB stick.
 Reconnect the USB stick and
repeat the export.
Failed to initialize
printer. • Printer not connected or switched
off.
• Printer not configured correctly.
 Connect the printer and switch it
on.
 Reconfigure the printer.
For a correct configuration of the
printer settings refer to the installation
description (see Connecting the printer
on p. 18).
Blank measurement: An
intensity on a pixel that
influences the main,
auxiliary or scan
wavelength is too low. • The absorbance of the blank
solution used for the blank
measurement is too high.
• Incorrect or turbid blank solution.
• For scans: Wavelength range is too
large, because the sample is very
strongly absorbed in part of the
wavelength range.
 Check the blank solution and
remeasure the blank if required.
 For scans: Match the wavelength
range to the sample spectrum.
Blank measurement: The
emission at the
measurement
wavelength is too high. • The fluorescence of the blank
solution used for the blank
measurement is too high.
• Incorrect or turbid blank solution.
 Check the blank solution and
remeasure the blank.
The entered name is not
valid. • Error when entering the name.
