Problem solving
Overview
This section will help you to troubleshoot and solve MFP problems.
Occasionally, paper can jam during printing. This section will help you to locate
jams, properly clear them from the MFP, and solve repeated jams.
Many different messages can appear on the control-panel display. Some
messages tell the current MFP status, such as
INITIALIZING
. Other
messages require action, such as
CLOSE RIGHT DOOR
. Most of these messages
are self-explanatory. However, some messages indicate a problem with the
MFP, or require further action or description. This section lists these types of
messages and tells you what to do if a message persists.
Correcting output
quality problems
The MFP should produce print jobs of the highest quality. If print jobs do not
appear sharp and clear, if defects such as lines, specks, or smears appear on
the page, or if paper is wrinkled or curled, use this section to troubleshoot and
solve the print quality problem.
Before you can eliminate an MFP problem, you must understand the location
of the problem. Use the tables in this section to determine the MFP problem,
and then follow the corresponding troubleshooting suggestions.
Software, computer,
and product
interface problems
Use the tables in this section to determine problems with the software or the
computer, and to diagnose interface problems that might affect job production.
Checking the MFP
configuration
From the MFP, you can print information pages, which provide details about
the MFP and its configuration.
