Troubleshooting
4.1 Introduction
The objective of troubleshooting is to relate a problem to an associated assembly or system
function, in order to most efficiently isolate and repair the problem. This involves determining
the failure symptom and then checking one or more possible causes of the failure.
Only a symptom-related list of possibilities appears. In general, for a given failure symptom
one or more possible causes are listed, with suggested corrective action to take. These causes
should be checked and corrective actions taken in the order given; they are listed in order of
likelihood and complexity.
When the suggestions presented fail to lead to a repair, a
CPU Board replacement, if not
prescribed, should nevertheless be tried. A check for broken or disconnected cables and any
loss of power should also take place along with checks for obvious mechanical damage.
Zebra Card Printer Solutions offers Technical Support and factory repair as options.
