MACHINE DIAGNOSTICS GUIDE
5.1
METHOD
A technique for carrying out the operation is described below that may guide the less expert service engineer.
5.1.1
ANALYSIS OF OCCURRENCE OF THE FAULT
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.
5.1.2
ANALYSIS OF OPERATING CONDITIONS
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.
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.
OPERATING STATUS OF THE PRINTER
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.
