Sequence of operation
The DC controller in the engine-control system controls the operational sequences of the product. The
following table describes durations and operations for each period of a print operation from the time
the product is turned on until the motor stops rotating.
Normal sequence of operation
Table 1-1 Sequence of operation
Name Timing Purpose
WAIT From the time the power switch is turned on, the door
is closed, or the product exits Sleep mode, until the
product is ready for a print operation.
STBY (standby) From the end of the WAIT or LSTR period until either
a print command is sent or the power switch is
turned off.
INTR (initial
rotation)
From the time the print command is received until the
product picks up a piece of paper.
Brings the product to printable condition:
Detects and heats the fuser
●
Detects the print cartridge and any cartridge
●
changes
Detects the ITB, and moves the ITB and the
●
developing unit to the home position
Cleans residual toner from the intermediate
●
transfer belt (ITB) and the secondary transfer
roller
Maintains the product in printable condition:
Enters Sleep mode if the sleep command is
●
received
Performs a calibration if the calibration
●
command is received
Prepares for the print job
Activates the high-voltage power supply
●
Activates the laser scanner
●
Opens the laser shutter
●
ENWW
Cleans the protective laser glass
●
Engages the print cartridges
●
Warms the fuser
●
Basic operation
3
Table 1-1 Sequence of operation (continued)
Name Timing Purpose
PRINT From the end of the INTR period until the last sheet
completes the fusing operation.
LSTR (last
rotation)
From the end of the PRINT period until the main
motor stops rotating.
Prints
Forms the image on the photosensitive drum
●
Transfers the toner image to the paper
●
Fuses the toner image to the paper
●
Moves the last printed sheet to the output bin.
Stops the high-voltage power supply
●
Stops the laser scanner
●
Closes the laser shutter
●
Cleans the protective laser glass
●
Disengages the print cartridges
●
Stops the fuser
●
The product enters the INTR period as the LSTR
period is completed, if the formatter sends another
print command.
4 Chapter 1 Theory of operation ENWW
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.
The formatter also provides the electrical interface and mounting locations for an additional DIMM.
Sleep mode
NOTE: In the Display Settings menu (a sub menu of the Administration menu), this item is
termed Sleep Mode.
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 15-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.
ENWW
Formatter-control system

Input/output
The product has three I/O interfaces:
USB 2.0 port for connecting directly to a computer
●
Internal 10/100Base-T network port
●
Walk-up USB port
●
CPU
The formatter incorporates a 800 MHz Vermillion processor.
Memory
The random access memory (RAM) on the formatter printed circuit assembly (PCA) contains the page,
I/O buffers, and the font storage area. It stores printing and font information received from the host
system, and can also serve to temporarily store a full page of print-image data before the data is sent to
the print engine.
NOTE: If the product encounters a problem when managing available memory, a clearable warning
message appears on the control-panel display.
Firmware
The firmware is contained in the internal solid state drive (SSD) or hard disk (HD). A remote firmware
upgrade process is used to overwrite and upgrade the firmware on the SSD or HD.
Nonvolatile memory
The product uses nonvolatile memory (NVRAM) to store device and user configuration settings. The
contents of NVRAM are retained when the product is turned off or disconnected.
PJL overview
The printer job language (PJL) is an integral part of configuration, in addition to the standard printer
command language (PCL). With standard cabling, the product can use PJL to perform a variety of
functions.
Two-way communication with the host computer through a network connection or a USB
●
connection. The product can inform the host about the control-panel settings which can be
changed from the host.
Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O.
●
The product can receive data from more than one I/O simultaneously, until the I/O buffer is full.
This can occur even when the product is offline.
