printing. To stop printing, press the FONT button or the
MENU button. Manually turn the platen knob clockwise to
remove the test page.
NOTE
Do not try to use the LF/FF (line feed/form feed) button to eject the
paper. In self-test mode, LF/FF cannot be used to feed paper
forward.
4. Examine the self-test page. It should look like the sample on
the next page.
Check that printing is uniform and that there are no light, dark,
or smudged areas. If the print quality is good, go to step 5.
Otherwise, try to correct the problem as follows:
• Make sure that the ribbon is installed correctly.
• Make sure that the paper thickness lever is set to position 1.
