DIAGNOSTICS GUIDE 5.1 SERVICING METHODS The following pages contain a technical approach to servicing that can be used as a guide by less experienced technicians. 5.1.1 INFORMATION CONCERNING THE FAULT The operator who has detected the fault can give information concerning the operating side and the error indications from the printer when the fault occurred.

  • Page 102: Pinpointing The Problem

    5.1.3 PINPOINTING THE PROBLEM Carefully examine all the information obtained (information from the operator, printer error signals, analysis of the documents where the fault has occurred, repetition of the error when starting up the machine etc.) to recognize and pinpoint the fault on the machine that is to be solved. At times the fault is generated by more than one cause: it is important in such cases to separate the faults and deal with them one at a time.
