Cleaning Your Machine
Your fax requires little periodic maintenance. This section describes the necessary cleaning
procedures for the fax. Please note the following before cleaning:
Do not use tissue paper, paper towels, or similar materials for cleaning; they can stick to the
components or generate static charges.
Caution
Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the
interior of the fax.
Note
There is the case that some of the data are lost when the power is turned off for cleaning. See "In Case of
a Power Failure" on page 73.
Cleaning the Exterior of the Machine
When cleaning the exterior of the machine, do not use tissue paper, rough-textured cloth, or
similar materials, as these may scratch the surface. Also, never use volatile liquids such as
thinners, benzene, acetone, or any other chemical cleaner to clean. Be sure to use a soft cloth
such as eyeglasses cleaning cloth and wipe off dirt on the surface with it gently. Smooth out
wrinkles on the cloth if necessary before cleaning.
Caution
Always unplug the machine from the power outlet before cleaning the machine. If you accidentally
switch the machine on while cleaning it, you could injure yourself.
Cleaning Inside of the Machine
To prevent ink spots and paper dust from accumulating inside the fax and affecting print quality,
clean the print area of the fax periodically.
Caution
Always unplug the machine from the power outlet before cleaning the machine. If you accidentally
switch the machine on while cleaning it, you could injure yourself.
