Formatter-control system
The formatter is responsible for the following procedures:
●
Controlling sleep mode
●
Receiving and processing print data from the various product interfaces
●
Monitoring control-panel functions and relaying product-status information (through the control
panel and the network or bidirectional interface)
●
Developing and coordinating data placement and timing with the DC controller PCA
●
Storing font information
●
Communicating with the host computer through the network or the bidirectional interface
The formatter receives a print job from the network or bidirectional interface and separates it into
image information and instructions that control the printing process. The DC controller PCA
synchronizes the image-formation system with the paper input and output systems, and then signals the
formatter to send the print-image data.
Sleep mode
NOTE: In the General Settings menu (a submenu of the Administration menu), this item is termed
Sleep Timer Settings.
This feature conserves power after the product has been idle for an adjustable period of time. When
the product is in Sleep Mode, the control-panel backlight is turned off, but the product retains all
settings, downloaded fonts, and macros. The default setting is for Sleep Mode to be enabled, and the
product enters Sleep Mode after a 30-minute idle time.
The product exits Sleep Mode and enters the warm-up cycle when any of the following events occur:
●
A print job, valid data, or a PML or PJL command is received
●
A control-panel button is pressed
●
A cover is opened
●
A paper tray is opened
●
The engine-test switch is pressed
NOTE: Product error messages override the Sleep message. The product enters Sleep Mode at the
appropriate time, but the error message continues to appear.
TIP: When the product is in Sleep Mode, the sub power supply is off and the low-voltage power
supply is on. The scanner can not be used when the product is in Sleep Mode.
