Make sure that you are using the correct page length and margin
settings in your application.
Make sure the correct paper size is set in the Tray Menu on the
control panel.
When loading paper for which the size is not specified with Auto

or on the MP Tray Size setting in the Tray Menu on the control
panel.
Confirm and adjust the offset values such as Feed Offset or Scan
Offset. See "Printer Adjust Menu" on page 90 for details.

Graphics require large amounts of memory. Install an appropriate
memory module. See "Memory Module" on page 117.
What to do
If the surface of your paper is too rough, printed characters may
appear distorted or broken. Smooth, high-quality copier paper is
recommended for best results. See "Available paper types" on
page 197 for information on choosing paper.
Clean internal printer components by printing three pages with
only one character per page.
