Troubleshooting Overview
Introduction
This section covers general problems that may occur with the printer. Malfunctions that trigger
system error messages can be caused by human error, a system malfunction, an interface cable
malfunction, mechanical printer malfunction and/or printer firmware failure.
Definition
Printer Errors
Some errors are problems that interfere with the print process but do not shut down the printer
completely. Typically, these errors are problems that prevent starting a printing job or that
interrupt the current print. You should be able to fix these errors without a service call. Other
errors stop the printer and prevent operation until the error is resolved. The printer interface
informs you as to what is wrong by displaying an error message on the LCD display. If the error
message has an obvious solution, apply the appropriate remedy. Otherwise note the exact error
message and associated error number and what the printer was doing before the error, then
place a service call.
Basic Troubleshooting
Troubleshooting helps you locate the source of errors and fix common problems that can arise
during printing.
Troubleshooting Areas:
• Printer behavior
• Print quality
• Data transfer
Example 1
If There is No Power
Is the printer connected to a working power source?
The service should be a dedicated supply that is not susceptible to voltage fluctuations. This
service must be provided via an independent, double pole, fused circuit breaker and a circuit
ground (computer grade) located near the machine. The service should meet all local and
national standards for this type of installation. The circuit breaker should be clearly labeled,
indicating the On and Off positions, such as '1' for On and '0' for Off. A suitable air gap should be
maintained for safe electrical isolation when in the Off position. The printer relies on this service
for primary branch protection. If the printer is without power, check the local supply voltage and
verify that it is set correctly.
Example 2
Drops of Ink Appear on the Media
• Check that the ink valves on top of the carriage are all open. If an ink valve is closed, there is no
vacuum pressure to hold the ink and it will drip out of the printhead.
• Check that there is no hair or other debris on the underside of the carriage. Objects can
accumulate ink mist and result in small drops of ink.
If Problems Persist
If problems persist, perform the following actions as appropriate for the situation:
