Troubleshooting: General Fault Isolation
See the MAC 5000 Operator's Manual, Chapter 2, "Equipment Overview:
Getting Started" to verify operation.
On power-up, the system automatically runs an internal self-test. If all
circuits test good, the start up screen displays. If the equipment is not
working properly, ask yourself the following questions.
Is the unit turned on?
Have there been any changes in the use, location, or environment of
the equipment that could cause the failure?
Has the equipment hardware or software been modified since last
use?
Is operator error the cause of the problem? Try to repeat the scenario
exactly and compare that to the proper operation of the equipment
described in the manual.
Is the battery installed?
When connected to the AC wall outlet, does the green AC power light
glow?
Is the writer door closed?
