CHAPTER 4
TROUBLESHOOTING
Typically, troubleshooting begins with an attempt to relate a problem to an associated component or system function. In this phase, servicing personnel may attempt to duplicate the problem and then use various means to test for a malfunction or improper system setup.
This chapter hopes to aid in this process by presenting a table that offers some areas related to an observed problem. Those with replacement components on hand can often speed up the repair process by swapping related components. This process either narrows the possibilities or eliminates the problem. Trial-and-error works particularly well with easily accessible components, such as those accessible by opening the cover or removing the rear case.
Only a symptom-related list of possibilities appears. 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 either ac or dc power should also take place along with checks for obvious mechanical damage. The Test Software described in Appendix A includes selections to exercise most printer functions. Beyond this, Eltron Card Printer Products offers Technical Support and factory repair as options.
