Cleaning the Machine

CAUTION

  • When performing maintenance on the machine, always disconnect the power cord from the wall outlet.
  • Contact your sales or service representative for cleaning the machine's interior. If the machine's interior is not regularly cleaned while dust accumulates, fire and malfunction can result.

Important

  • Do not use chemicals such as cleaning liquid and organic solvents such as paint thinner and benzene for cleaning. It may seep inside the machine through the gaps or melt the plastic material composing the exterior cover, causing malfunctions to occur.

  • Your local dealer will replace the ozone and dustproof filters as needed.

  • Do not clean parts other than those explicitly specified in this manual. Other parts should only be cleaned by your local dealer.

Cleaning the Power Cord Plug

For safety, clean the power plug at least once a year.

Use a dry cloth to wipe any dust from the plug.

Important

Note

  • After cleaning the power cord plug, make sure that the power cord is connected to the machine firmly, and then connect the plug to the wall outlet.

WARNING

  • To prevent fire or electric shock, disconnect the plug and the power cord from the wall outlet at least once a year and check them. If any of the following conditions exist, do not use the plug and the power cord continuously, and consult your dealer or service representative.
    • There are burn marks on the plug

    • The prongs on the plug are deformed

    • The power cord's inner wires are exposed or broken

    • The power cord's coating is cracked, dented, or damaged
