Page: 90 / 131

Symptoms and Causes
The following pages list some known symptoms and typical causes.
These lists are in no way complete and can not replace systematic
troubleshooting. The service representative must have a solid
foundation of system knowledge and wax jet printing principles, as
well as basic electronic troubleshooting abilities to progress beyond
these lists.
WARNING
Check heater circuits first whenever priming problems
occur. If wax flow is restricted due to lack of heating, you
can burn your hand when attempting to prime.
