3. Gently remove any paper inside the printer, including any
torn pieces. You can use the knob on the right side of the
printer to help feed the paper out.

c
Use the paper feed knob to clear paper jams only when the
printer is off. Otherwise, you may damage the printer or
change the top-of-form or tear-off position.

printer. Make sure the Paper Out light is not flashing and the
Pause light is off.

Printing a self test

Running the printer's self test helps you determine whether the
printer or the computer is causing the problem:
❏ If the self test results are satisfactory, the printer is working
properly and the problem is probably caused by your
printer driver settings, application settings, computer, or
interface cable. (Be sure to use a shielded interface cable.)
❏ If the self test does not print properly, there is a problem
with the printer. See "Problems and solutions" on page 79
for possible causes and solutions to the problem.
You can print the self test using either single sheets or
continuous paper. Be sure to use paper that is at least 8.25 inches
(210 mm) wide to run the self test; otherwise, the print head
prints directly on the platen.
