13 Have you loosened the paper sufficiently prior to loading it into the
sheet feeder?
Paper must be riffled several times prior to being loaded into the sheet
feeder. If not, sheets of paper may stick to one another and cause
multiple sheets to feed into the printer at the same time, or other forms
of misfeed.

Refer to Chapter 1, Introduction for details on removing packing
material.
2 Has the packing tape on the case been removed?
There are two pieces of tape on the front of the printer that help protect
the printer during shipping. These must be removed before using the
printer.

Open the front cover and make sure the ink cartridges are correctly
installed.

colours of ink cartridge installed in the printer?
Colour printing requires that four colours of ink cartridge (yellow,
magenta, cyan, and black) are installed with the OKI logo (B side)
facing up.

If Automatic is selected in Document Type, colour ink cartridges must
be installed even when printing monochrome. If you want to print using
only black ink, select
