Periodic cleaning
Your fax requires little periodic maintenance. This section describes the necessary cleaning
procedures for the fax. Please note the following before cleaning:
• Be sure to disconnect the power cord before cleaning the fax. Since documents in memory are
erased when the power is disconnected, print any documents stored in memory before
disconnecting the power cord (see p. 5-14).
• Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the
components or generate static charges.

clean the interior of the fax.

documents you copy or send.
