Machine Diagnostics; Operating Condition Analysis; Identifying The Problem - Olivetti PR2 PLUS Service Manual

MACHINE DIAGNOSTICS

A technique for carrying out the operation is described below that may guide the less expert service engineer.
The operator who has detected a malfunction is able to provide information about operating status and the error
signals output by the printer when the fault occurred.
Repetition of the fault, where possible, may make it easier to trace the problem.
For diagnostic purposes, it is important to check whether the fault is repetitive or occasional.

Operating condition analysis

Working environment
•
Certain problems may be caused by the environment if this is too cold, hot or damp.
•
The machine must not be positioned close to air conditioning system outlets or exposed to the rays of the sun.
•
Check that the internal ventilation slots are not obstructed especially if the printer is installed in a cabinet.
•
Certain forms, documents or office accessories placed close to the machine may reduce internal ventilation
with consequent overheating.
•
Avoid leaving on the cover or in the vicinity of the printer, staples, elastic bands or other small objects that could
be sucked inside.
Accessories and forms
•
Check that the accessories fitted on the machine are original and in good condition.
•
Check that the documents inserted in the printer comply with machine specifications and are in good condition
as described in the section
3.
Printer operating status
•
Check for any dirt or paper and ink on inside parts of the machine that may affect the performance of the
various devices.
•
Check for any internal damage due to insertion of documents with paper-clips, metal staples, pins or sample
holders.
•
Check lubrication of all parts for which this is prescribed. See the section

Identifying the problem

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.
