Formatter System The Formatter PCA is responsible for the following: q Controlling the PowerSave mode. q Receiving and processing print data from the various printer interfaces. q Monitoring Control Panel inputs and relaying printer status information (through the Control Panel and the Bidirectional I/O). q Developing and coordinating data placement and timing with the print engine. q Storing font information. q Communicating with the host computer through the Bidirectional Interface. The Formatter PCA receives a print job from the Bidirectional Interface and separates it into image information and instructions which control the printing process. The DC Controller Board synchronizes the Image Formation System with the Paper Input and Output Systems, and then signals the Formatter to send the print image data. The Formatter PCA also provides the electrical interface and mounting locations for two EIO cards, additional memory DIMMs, and the Hard Disk accessory. PowerSave This feature (accessed from the Configuration Menu) conserves power by shutting down the Fuser and exhaust fans after the printer has been idle for an adjustable period of time. The printer retains all printer settings, downloaded fonts, and macros while in PowerSave mode. The default setting is POWERSAVE ON, with a 30-minute idle time. 5-12 Functional Information EN
