Technical information

The printer prints on one side even though duplex printing is specified.
If your document prints in simplex mode (only on one side) instead of duplex
mode, check the following:
m Is the optional duplex printing unit installed?
m Is duplex printing selected in the Print dialog box?
Unwanted lines or stripes appear.
If white or dark vertical or horizontal lines or stripes appear on the page, try
the following remedies. (Each procedure is described in detail in “Replacing
the Toner Cartridge” in Chapter 10.)
m Gently rock the cartridge to redistribute the toner.
m Replace the toner cartridge.
The image is wavy or distorted.
If a gray shaded area appears wavy or distorted, the toner cartridge may be
low, or the toner may need to be redistributed (see “Replacing the Toner
Cartridge” in Chapter 10).
