Use the platen knob to back the paper out of the
printer.
CAUTION!
Make sure the printer is turned off before you open the
access cover.
Open the access cover and remove the pull-up
roller assembly.
Use a clean, dry cloth to dust around the carriage
shaft and platen. Remove any loose bits of paper.
Reinstall the pull-up roller assembly and close the
