Diagnosing the Problem
Troubleshooting printer problems is best handled in two steps: first diagnose the problem, then apply likely solutions
until the problem is fixed.
The information that you need to diagnose and solve most common problems is provided by online problem solving,
the control panel, the status monitor, or by running a printer operation check. Refer to the appropriate section below.
If you have a specific problem relating to print quality, a printing problem not related to print quality, or a paper
feeding problem, or if the printer does not print at all, refer to the appropriate section.
To solve a problem, you may need to cancel printing.
