Identifying Faults by Symptom
When it is not possible to identify a fault by the visible effect on the print sample, it becomes necessary
to look for other symptoms. For example, it may not be possible to start the jet satisfactorily, so it will
be impossible to obtain any sort of print. However, in most circumstances there will be some obvious
indication as to the nature of the fault, the best example being the fault messages displayed in the screen
status line.
The “ Warning and Fault Messages” section lists all of the warning and fault messages. This section
also gives a detailed explanation of the condition that the printer control logic has detected which has
resulted in the particular message being displayed.
If there is no fault message, or if the message on its own is not enough to identify the problem, refer to
the following list of symptoms to identify the possible cause of the fault. The list is organised to group
the symptoms into the five different stages of printer operation:
1. Before switching on.
2. After switching on.
3. When the jet is started.
4. During printing.
5. After the jet is stopped.
Note that these groupings only indicate the earliest point at which the symptom could be observed; the
symptom could also be observed later in the cycle of printer operation. For example, solvent
contamination might be observed at any time, but it is included in the first group because it is possible
to check this symptom before switching on.
The text below each symptom describes the different types of fault that can give rise to the symptom,
with references to fault code numbers by which the faults are identified in the “Problem Solving ” sub-
section, where the problem and its method of rectification is described in more detail.
