Check that the interface cable is not broken or twisted. If you have
another interface cable, replace the cable and check whether the
printer works correctly.
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.
Check that the printer driver is installed properly. If necessary,
reinstall the printer driver.
Turn the printer off, open the printer cover and remove the
jammed paper or things that are stuck.
Confirm the USB setting is correct. See "Correcting USB Problems"
on page 111 for details.
Turn the printer off and wait for a while. Then, turn the printer on
again, and start printing.
What to do
Press the Pause button to turn off the Pause light.
Check that both ends of the cable between the printer and the
computer are plugged in securely. If the cable is connected
correctly, run a self test as described in "Printing a Self Test" on
page 114.
Use an interface cable that meets the requirements of both the
printer and computer. See "Electronic" on page 145 and your
computer documentation.
Select your printer from the Windows desktop or in your
application. If necessary, install or reinstall the printer driver
software as described in the supplied setup sheet.
What to do
Set the paper-thickness lever to match the thickness of your paper.
See "Adjusting the Paper Thickness Lever" on page 19 for
instructions.
Remove any slack in the ribbon by turning the ribbon-tightening
knob, or reinstall the ribbon cartridge as described in "Replacing
the Ribbon Cartridge" on page 120.
