PostScript Fax Option Cards maintain their own clock which is supported by a long-life battery when the LaserWriter is off. This Fax clock is compatible with and accepts the new millennium date formats, such as March 10, 2000.
The date and time may be set from Macintoshes via the LaserWriter Fax Utility, or from DOS/Windowsµ3.1 via the Fax Control Panel. Step-by-step procedures for changing the clock settings are documented in the Fax Card User's Guide.
This pertains to any Apple Fax Option Cards available for the LW Pro 810, LW Select 360, and LW 16/600.
