5-16 Functional Information
Note Printer error messages override the PowerSave message. The printer
will enter PowerSave mode at the appropriate time, but the error
message will continue to be displayed.
Resolution Enhancement technology (REt)
The Formatter PCA contains circuitry for Resolution Enhancement
technology (REt), which modifies the standard video dot data on its
way to the Engine Controller Board to produce “smoothed”
black-to-white boundaries. REt can be turned on or off from the
Control Panel, or from some software applications. The default setting
is medium.
Note REt settings sent from software applications or printer drivers override
the Control Panel settings.
EconoMode
The EconoMode setting uses up to 50% less Toner than standard
mode printing by reducing the dot density. However, EconoMode
does not extend Toner Cartridge component life. EconoMode, which
can be thought of as “draft mode” can be selected from the Control
Panel (Print Quality Menu) and through some software applications
and printer drivers. The default setting is off.
Note EconoMode does not affect print speed, memory usage, nor extend
the Toner Cartridge’s life.
