Cleaning the Housing

You should clean the printer every six months (or after about

300 hours of operation).

Note: Never use solvents or strong detergents on the

cabinet: they could damage the housing.

1. Turn the printer off, and remove any paper from the path.

2. Open the access cover, remove the pull-up roller assembly.

3. Use a clean, dry cloth to dust around the carriage shaft

and platen. Remove any loose pieces of paper.

4. Reinstall the pull-up roller assembly, and close the access

cover.
