10. Troubleshooting
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-contract 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 combines 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 most simple possibilities.
10.1. Where to Start
All problems with printer operation are distinguished from each other by the symptoms displayed.
These symptoms can be obvious faults with 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:
10.1.1.1. 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.
10.1.1.2.
Use the “Identifying Faults” sub-section to identify all the possible causes of the
symptoms that the printer is displaying.
10.1.1.3. 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 id established.
10.1.1.4. 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.
10.1.1.5. 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
