Cleaning the Platen Glass and Document Cover


  • Be sure to turn off the power and disconnect the power plug before cleaning the printer.

    • The power cannot be turned off while the printer is sending or receiving a fax, or when unsent faxes are stored in the printer's memory. Make sure if the printer completed sending or receiving all the faxes before disconnecting the power plug.

    • The printer cannot send or receive faxes when the power is turned off.

    • If the power plug is disconnected, the date/time settings will be reset and all documents stored in the printer's memory will be lost. Send or print a necessary document, or save it on a memory card or USB flash drive before disconnecting the power plug.

  • Do not use tissue paper, paper towels, rough-textured cloth, or similar materials for cleaning so as not to scratch the surface. Paper tissue powder or fine threads may remain inside the printer and cause problems such as print head blockage and poor printing results. Be sure to use a soft and dry cloth.

  • Never use volatile liquids such as thinners, benzene, acetone, or any other chemical cleaner to clean the printer, as this may cause a malfunction or damage the surface of the printer.

With a soft, clean, lint-free and dry cloth, wipe the platen glass (A), the inner side of the document cover (white sheet) (B), the glass of the ADF (Auto Document Feeder) (C), and the inner side of the ADF (white area) (D) gently. Make sure not to leave any residue, especially on the glass surface.


  • The inner side of the document cover (white sheet) (B) is easily damaged, so wipe it gently.

  • If any foreign substances such as glue, ink or correction fluid are adhered to the glass of the ADF (C) as shown in the figure above, some black streaks will appear on the scanned image. 
    In this case, wipe the dirt off gently.
