IDENTIFYING THE PROBLEM

5.1.3
Examining all the information gathered (from the Operator, printer error signals, analysis of documents on
which the fault has been encountered, repetition of the error when the machine is started, etc.), trace and
isolate the problem that has occurred on the machine and which must be eliminated.
In some cases, the fault may be caused by more than one problem: it is important therefore to separate the
various problems and deal with these one by one.

TRACING THE CAUSE

5.1.4
According to your experience, and referring to information provided in this chapter, follow a logical path to trace
the fault, from the most likely cause to the most remote possibility, until you have identified the faulty part.

ELIMINATION OF THE FAULT

5.1.5
Carry out the repair so that the machine can carry out all its functions
In this phase, the information provided in chapters 6, 7, 8, 9 may be of help.

TESTING OF THE MACHINE

5.1.6
Once the machine has been repaired, carry out a general cleaning and complete test of the machine
(paragraph 3.5), possibly with the Operator present, to check that the problem has been eliminated and that no
other faults have occurred.
