Troubleshooting
This section helps you solve problems with the printer.
If the printer is making strange noises, emitting smoke or strange
smells, turn the printer off immediately and unplug the AC power
cord. Call for service. Never attempt to disassemble the printer or
repair it.
Troubleshooting diagnostic tests
If you experience a problem, perform the three diagnostic tests described
below to identify problems with the printer performance, printer-to-comput-
er connection, or driver installation/selection.
Before you begin, always check the printer cable connection at the back of
the printer and the computer. A loose printer cable at the printer or host
computer can cause intermittent problems.

Do not use paper smaller than A4 or Letter size.
2

out of ink. Refer to Troubleshooting Problems and Solutions below.
