Phaser 4400 Laser Printer Overview

The Phaser 4400 Laser Printer combines a monochrome print engine with an image

processor supporting PostScript 3 and PCL5e/6. The Phaser 4400 is a high

performance, 26 ppm desktop laser printer with a resolution up to 1200 x 1200 dpi.

Configurations

The Phaser 4400 is available in four configurations. A replaceable “Configuration

Upgrade Chip” holds configuration information that enables or disables built-in

features as described here.

Phaser 4400B The Phaser 4400B is the base configuration laser printer. The printer

comes standard with 32 Mbytes of memory, 600 x 600 dpi resolution, USB and

Parallel support, a built in Multi-Purpose Tray, and a 550-sheet universal paper tray.

Note: The Phaser 4400B reports 32 Mbytes of memory even though

it has a 64-Mbyte DIMM installed. In order to get the full

64 Mbytes of memory to be reported as well as activate other

features, users need to upgrade to the N-configuration with a

Configuration Upgrade Kit, part number 098S04703.

Phaser 4400N The Phaser 4400N is the networking configuration. This

configuration includes all the features of the 4400B, but comes with 64 Mbytes of

memory, built-in 10/100 Ethernet networking capabilities, and a resolution up to 1200

x 1200 dpi.

Phaser 4400DT The Phaser 4400DT includes all the features of the 4400N but

comes standard with built in auto-duplexing, and one added 550-sheet feeder.

Phaser 4400DXThe Phaser 4400DX includes all the features of the 4400DT, along

with a 20-Gbyte hard drive and a Stacker with offset.

Printer Memory Configuration

The printer features two slots which accept 32-, 64-, and 128-Mbyte SDRAM

DIMMs. All combinations except 32 Mbytes alone are allowed to a maximum of 256

Mbytes.

The Phaser 4400B reports 32 Mbytes of memory, even though it has a 64-Mbyte

DIMM installed. In order to get the full 64 Mbytes of memory to be reported as well

as activate other features, users must upgrade to the N-model with a Configuration

Upgrade Kit, part number 098S04703.

The Startup page and the Configuration pages list the amount of RAM installed in the

printer.

If the memory does not meet the following specifications, it is ignored by the printer.

■PC133 DRAM Standard

Image Processor Board

The following components must be transferred from the old board when installing a

new Image Processor Board in the printer:

■SDRAM DIMMs (Slot 1 on the left, slot 2 on the right)

■NVRAM

■Configuration Upgrade Chip

■Flash DIMM

See RRP 9.2 Image Processor Board on page 6-88 for information on replacing the

Image Processor Board.

Inside the printer on the Image Processor board are four LEDs shown in the figure.

DS210 illuminates when the e-net rate is set to 10 Mbits/sec (off indicates

100 Mbits/sec).

DS211 illuminates when a link is established.

DS380 is the HEALTH LED. The CPU flashes this LED to indicate that it is “alive”,

or in the case of a failure, the CPU flashes this LED (and the Front Panel LED, also)

with a code to help diagnose the problem.

DS390 is the CHECK STOP indicator, which illuminates when various fatal errors

occur in the CPU.
