Formatter system
The formatter PCB is responsible for the following:
● receiving and processing print data from the various printer interfaces
● monitoring control panel inputs and relaying printer status information (through the
control panel and the bidirectional I/O)
● developing and coordinating data placement and timing with the print engine
● storing font information
● communicating with the host computer through the bidirectional interface
● controlling the PowerSave mode
The formatter monitors the printer continuously through the video interface. When the printer
is ready to print, the formatter sends a signal to the DC controller, which turns the laser on or
off based on the signal.

PowerSave
This feature conserves power after the printer has been idle for an adjustable length of time.
Set the time length in the Configure Device menu, under System Setup. When the printer is
in PowerSave mode, the control panel backlight is turned off, but the printer retains all printer
settings, downloadable fonts, and macros. The default setting is Powersave on, with a 30-
minute idle time. You can turn PowerSave off in the Configure Device menu, under Resets.
