R-Key Setting

If your machine is connected to a PBX (Private Branch Exchange), it is necessary to set the access method. You can set the PBX type to [Prefix] or [Hooking]. If you register the outside line access number in the R-Key, you can easily access the outside line.
If you are using the imageRUNNER ADVANCE C350i/C250i, this mode can be set when the Fax function is available for use. For information on the optional products required to use the Fax function, see "Optional Products Required for Each Function."
