Chapter – Troubleshooting 37
Basic troubleshooting
If you cannot determine the cause of your print defects by using
information from the previous section, try the following procedures:
1 Try print media from another lot or from a different manufacturer.
2 Flip the paper over in the input tray, or turn it from front to rear
(both, if necessary).
3 If you have an envelope print-quality problem, print a sheet of
paper to determine if the problem is caused by the variable
thickness of your envelope.
• If the paper’s print quality is good, re-examine your envelope
and see "Envelope construction" for more information.
• If the paper’s print quality is poor, you might have a printer
problem. See the documentation that came with your printer
for further troubleshooting.
4 Read the rest of this Troubleshooting section for further
troubleshooting information, perform the maintenance
procedures recommended in your printer user guide, or see the
troubleshooting section in your printer user guide.
