WARNING IF THIS TEST PASSES, DO NOT REPLACE THE HARD
DISK DRIVE.
If there is a problem with the Hard Disk Drive then the test will fail
and the following message will appear on the front panel:
NOTE Check that the Hard Disk Drive is actually installed before
starting to troubleshoot. If the Hard Disk Drive is NOT installed,
the test will of course always fail.
In this case, to resolve the problem, try the following:
1 Switch the printer OFF. Remove the EIO Card (if installed) and
reinstall the Hard Disk Drive making sure it installed correctly by
pushing it firmly inwards and checking that the two installation
screws are completely tightened. Switch the printer ON again and
repeat the Hard Disk Drive Test. If the Hard Disk Drive Test fails
again then replace the Hard Disk Drive.
2 If the Hard Disk Drive Test passed after removing the EIO Card,
then switch the Printer OFF and reinstall the EIO Card, making
sure that the two installation screws are completely tightened.
Switch the Printer ON again and repeat the Hard Disk Drive Test. If
the Hard Disk Drive Test fails, then the EIO Card could be faulty.
Replace the EIO Card.
3 If the Hard Disk Drive Test continues to fail after replacing the EIO
card or the Hard Disk Drive, then replace the Electronics Module
