The printer is not connected directly to your
computer.
When you use a printer changer, printer buffer, or a extension
cable, the printer does not print correctly due to the combination
of these devices. Make sure that the printer works correctly when it
is connected to your computer without these devices.
The printer driver is not installed correctly.
Check that the printer driver is installed properly. If necessary,
reinstall the printer driver.

mechanism is stuck.
Turn the printer off, open the printer cover and remove the
jammed paper or things that are stuck. To eject the jammed paper,
see “Clearing a Paper Jam” on page 58.
The printer is hung-up (stopping in abnormal
situations).
Turn the printer off and wait for a while. Then, turn the printer on
again, and start printing.
