Formatter-control system
The formatter is responsible for the following procedures:
●
Controlling power states of the product
●
Receiving and processing print data from the various product interfaces
●
Monitoring control-panel functions and relaying printer-status information (through the control
panel and the network or bidirectional interface)
●
Developing and coordinating data placement and timing with the DC controller printed circuit
assembly (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.
Auto on/Auto off mode
This feature conserves power after the product has been idle for an adjustable period of time by using
two power-saving modes: Sleep mode and Auto off mode.
The product enters Sleep mode after a specified period of idle time. The default idle time to enter Sleep
mode is fifteen minutes. The “Ready” LED on the front of the product remains lit when the product is in
Sleep mode.
The product enters Auto on/Auto off mode after a specified period of idle time. The default idle time to
enter Auto off mode is thirty minutes. The “Ready” LED on the front of the product turns off when the
product is in Auto on/Auto off mode.
The product enters Auto off/Manual on mode after a specified period of time when no wake events are
selected.
