Recovery from Hardware Errors
When a hardware failure occurs, a message is displayed on the control panel.
If
the failure occurs during the power-on sequence, DEVICE FAILED is
displayed.
If the failure occurs when loading a disk you may see LOAD ERROR
or FULL. If a failure occurs while you are running a test, TEST FAILED is
displayed. When you press ENTER, the autochanger displays information about
the hardware failure that is held in the error log.
The autochanger firmware can detect broken components such as a dead motor,
but if failures are due to marginal or random problems, the failing component
may induce errors in other components.
For example, if any portion of the
electronics becomes intermittent or if friction increases on a part, different
components of the autochanger may appear to fail at varied points as the
autochanger runs its code.
This results in many different error codes.
The following table shows the hardware error codes possible and recovery
procedures for specific hardware errors.

01
ROM checksum error
01 thru 07 are controller tests.
These errors only possible on
power up. If you get these errors,
replace the controller PCA.
