Print quality problems
Your printer provides a full troubleshooting utility to ensure you can always quickly overcome any image problems
you encounter. You should use this utility whenever you (and not the printer) perceive a problem with print quality.
Often what you believe to be a print quality problem is in fact caused by incorrect configuration of the printer for
the type of image you are trying to print. Always check
Configuration correction as your first diagnostic task to find
the cause of your problem.
If a message, such as “PRINTHEADS not functional” appears on the front panel of your printer, follow the
instructions given for the particular message (see
Message descriptions ).
The types of problems you could possibly encounter are:
•
Stepped lines
• Incomplete lines
• Color accuracy
• Horizontal banding
• Color alignment
Whenever you see any of these problems, work through the Troubleshooting procedure replying to the questions
displayed on the front panel. This will lead you to correct remedial action required to solve your print quality
problem.
