Cleaning

the cleaning tool. Unsnap the cleaning tool from
its holder. The corona wire is located directly in
front of the transfer unit. Hook the cleaning tool
under the transfer unit with the clear “needle’
facing you. As you slide the cleaning tool back
and forth a few times to remove any toner
buildup, you hear a clicking sound. If you do not
hear this sound, the tool is not seated correctly.
Return the cleaning tool to its mounting in the
