Troubleshooting; Where To Start - EC-PACK EC-JET 1000Pro Manual

Troubleshooting

Introduction
This section provides general advice on fault diagnosis on the EC-JET Ink Jet Printers, as well as specific
procedures for identifying and rectifying faults. Fault diagnosis is complicated by the number of variables
involved in producing good print quality. Fast, non-contact printing involves fluid dynamics, physics,
electronics, computing and chemistry.
Many of the faults that could occur within the printer are self-diagnosed by the integral software. Upon
diagnosis, the operator is alerted by way of error messages (warnings and faults) which appear in the
status line of the display screen.
Before attempting any fault diagnosis for the first time, operators are advised to familiarize themselves
with the "Warning and Fault Messages" section of this manual, as it contains information which is useful
in rectifying many simple faults.
Problems can be found to have either a single cause or several combined causes. The complications
arising from the simultaneous failure of several different components make it impossible to consider such
faults in this user manual. In this section, individual problems are linked to their most probable causes.
The most successful fault diagnosis technique will be found by investigating each problem, separately, in
turn. Do not begin by assuming the most complicated combination of faults; always start by investigating
the simplest possibilities.

Where to Start

10.1
All problems with printer operation are distinguished from each other by the symptoms displayed. These
symptoms can be obvious faults with the print quality; error messages on the display; or any other signs
by which it is apparent that the printer is not functioning correctly. When the symptoms have been
correctly identified, the possible cause(s) of the symptoms the printer is displaying can be investigated.
The recommended fault diagnosis sequence is as follows:
1. Collect as much information as possible on ALL the symptoms that the printer is displaying, including
error messages, print samples and signs of electrical or mechanical malfunctions.
2. Use the "Identifying Faults¡" sub-section to identify all the possible causes of the symptoms that the
printer is displaying.
3. Start with the most probable cause, and investigate each of the possible causes in turn. This will
eliminate all the possible causes that are not responsible for the problem, until the actual cause is
established.
4. When the actual cause of the symptoms has been established, use the "Problem Solving" sub-section
to perform the necessary adjustments and repairs to rectify the fault.
5. Finally, check that the printer operates correctly and that any error messages have been cleared, and
that there is not a second fault causing supplementary symptoms.
If, after rectifying one fault the symptoms have not been eliminated, continue with the fault diagnosis
until all faults have been identified and rectified. Only when all faults have been eliminated, and the
printer is operating correctly, has the fault diagnosis been completed.
