Cleaning the Housing
You should clean the printer housing every six months (or after
about 300 hours of operation).
CAUTION!
Never use strong solvents or strong detergents on the
cabinet—they could damage the housing.
1 Turn off the printer.
2 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.
3 Open the access cover (1) and remove the pull-up roller
assembly (2).
4 Use a clean, dry cloth to dust around the carriage shaft and
platen. Remove any loose bits of paper.
5 Reinstall the pull-up roller assembly and close the access
cover.
