Printing problems
238 6. Troubleshooting
The machine does not
print custom-sized paper,
such as billing paper. Paper size and paper size setting do not match. Set the correct paper size in the Custom in Paper tab in Printing Preferences (see
"Opening printing preferences" on page 43).
The printed billing paper
is curled. The paper type setting does not match. Change the printer option and try again. Go to Printing Preferences, click Paper tab,
and set type to Thin (see "Opening printing preferences" on page 43).
