Formatter system The formatter is involved in the following procedures. ● Controlling the Sleep mode ● Receiving and processing print data from the various product inputs ● Monitoring control-panel functions and relaying product status information (through the control panel and the bidirectional input/output) ● Developing and coordinating data placement and timing with the DC controller PCA ● Storing font information ● Communicating with the host computer through the bidirectional interface The formatter receives a print job from 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 the memory DIMM and the hard-disk (hard disk drive or solid state drive). Sleep mode When the product is in Sleep mode, the control-panel backlight is dimmed, but the product retains all product settings, downloaded fonts, and macros. The default setting is a 30-minute idle time. Sleep mode also can be turned off from the Administration menu on the control panel.
The product exits Sleep mode and enters the warm-up cycle when any of the following occurs. ● A print job, valid data, or a PML or PJL command is received at the serial port. ● A control panel key is pressed. ● The top cover is opened. ● The engine-test button is pressed. NOTE: Error messages override the Sleep message. The product enters Sleep mode at the appropriate time, but the error message continues to appear. Input/output The following sections discuss the input and output features of the product. USB The product includes a universal serial bus (USB) 2.0 connection. 8 Chapter 1 Theory of operation ENWW
