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 the 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 the 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.
The formatter also provides the electrical interface and mounting locations for one EIO card, one
memory DIMM, two USB host ports, the hard-disk accessory, and the optional analog fax accessory.
Sleep delay
This feature conserves power after the product has been idle for an adjustable period of time. When
the product is in Sleep Delay, the control-panel backlight is turned off, but the product retains all
settings, downloaded fonts, and macros. The default inactivity setting is for Sleep Delay is 15 minutes.
The product exits Sleep Delay and enters the warm-up cycle when any of the following events occurs:
To change the inactivity setting for the Sleep Delay function, see the Energy Settings item in the General
Settings sub menu in the Administration menu.
●
A print job, valid data, or a PML or PJL command is received
●
A control-panel button is pressed or you touch the touchscreen
●
A cover or door 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.
Image Resolution Enhancement technology
NOTE: Resolution Enhancement technology (REt) settings that are sent from software programs or
product drivers override the control-panel settings.
