Formatter System

The Formatter PCA is responsible for the following:

Controlling the PowerSave mode

Receiving and processing print data from the various printer interfaces

Monitoring Control Panel inputs and relaying printer status information (through the Control Panel and the bidirectional I/O)

Developing and coordinating data placement and timing with the print engine

Storing font information

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 Engine 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, and the HP Fast InfraRed Receiver

(HP LaserJet 4050 series printer only).

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. (PowerSave can also be turned OFF from the Control Panel.)

The printer exits PowerSave 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 parallel port, serial port, FIR port, and EIO card

A Control Panel key is pressed

The Top Cover is opened and then closed

A paper tray is opened and then closed

The Engine Test button is pressed
