Good to know

  • When sending a double-sided document, load the document on the glass. Double-sided documents can't be auto scanned from the document feeder

  • Faxes may reach unintended recipients if there is a misdial or a wrong number. When you send important documents, we recommend that you first speak on the telephone.

  • When your machine is connected to a PBX (Private Branch Exchange) system, refer to the operating instructions of the system for details on dialing the recipient's fax/telephone number.

  • In case the machine can't send a fax, such as when the recipient's line is busy, it can redial the number after a specified interval. Automatic redialing is enabled by default.

  • Color transmission is available only when the recipient's fax machine supports color faxing.

  • When you send a color fax, documents always scan in (200 x 200 dpi) resolution. The image quality (compression rate) is determined by the resolution you select.

  • If you disconnect the power plug, all unsent documents stored in the machine's memory are lost.
