NOTE NOTE Power Save This user-adjustable feature conserves power by shutting down the fuser and exhaust fans after the printer has been idle for 15 minutes, 30 minutes, 1 hour, 2 hours, or 3 hours. A 10 second interval is also available in Service Mode. The printer retains all printer settings and downloaded fonts and macros while in Power Save mode. The default setting is Power Save ON, with a 15 minute idle time. (Power Save can also be turned OFF from the control panel.) The printer exits Power Save mode and enters the warm up cycle when any of the following occur: • A job is printed. • A control panel key is pressed. • The printer front door is opened and closed. • A paper cassette is removed or installed. Printer error messages override the Power Save message. The printer will enter Power Save mode at the appropriate time, but the error message will continue to be displayed. Resolution Enhancement (REt) The Formatter PCA contains circuitry for Resolution Enhancement technology (REt), which modifies the standard video dot data on its way to the DC Controller to produce "smoothed" black-to-white boundaries. REt is user-adjustable from the control panel, or from some software applications. Available settings are Light, Medium, Dark, or Off. The default setting is Medium. REt settings sent from software or printer drivers override any control panel settings. Functional 5 Overview Functional Overview 5-11
