CHAPTER 1 GENERAL DESCRIPTION

I . OUTLINE OF THE PRODUCT

This printer board is designed for installation inside a copier of the GP605/605V Series to

enable the copier to function as a printer.

The printer board comes standard with an IEEE1284-compatible parallel port (bi-Centronics) and an Ethernet interface for connection to a computer, not requiring any other board for connection to a network.

In addition to the generally used 10Base-T network interface, the printer board also supports 100Base-TX, developed for high-speed networks.

The printer board supports such network protocols as TCCP/IP, IPX/SPX, and AppleTalk so that it is capable of printing print data from a network on which these protocols exist concurrently.

The printer board uses PostScript 3 (page description language), and comes standard with 136 different Alphanumeric fonts.

B. Parts of the Printer Board by Function

The printer board has the following parts, each with its own function:

Flash ROM RIP chips PCI slot Hard disk

CPU

DIMM

DIMM Expansion slots

Network interface Parallel interface

Figure 2-102 (top view)

CPU It is a RISC type CPU (MIPS R5000) capable of high processing speed. It processes data according to the instructions of the programs in memory.

DIMM The DIMM area is roughly divided into a system area and an image data area: in the system area are found the program used to control the overall operation of the printer board and the program called a "PostScript interpreter," which interprets PostScript commands to generate image data; the image data area is used to store image data generated from PostScript files.

Flash ROM The flash ROM contains the programs for running self diagnosis (driven at start-up), for booting the system program, for formatting the hard disk and writing the system program.

RIP Chip The RIP chip is used to transfer data between memories and control the interface, thereby ensuring that the CPU processes print data efficiently.

CHAPTER 2 BASIC OPERATIONS

Network Interface It is used for connection to a network, and supports 10Base and 100Base-TX Ethernet systems.

Parallel Interface It is used for connection to a computer, and is compatible with IEEE1284 standards.

PCI Slot It is a 32-bit PCI (Peripheral Component Interconnect) connector for future expansion.

CHAPTER 2 BASIC OPERATIONS

II . BASIC OPERATIONS

A. Start-Up Sequence

When the copier's main power switch is turned on, the system power supply is provided with

power, ultimately supplying the EX board and the printer board unit with power.

When the printer board is supplied with power, its CPU runs the self diagnosis program stored

in its flash ROM, showing the result on the copier's control panel.

When a check on each part ends normally, the boot program stored also in the flash ROM starts

to read the system program from the hard disk drive for writing to the main memory.

When the write operation ends, the system program starts and shows the Idle message on the

touch display as soon as all parts have been properly prepared.

The system program of the printer board consists of a number of modules, of which the ones

needed for the processing in question are called into the system area of the main memory (RAM).

'Idle' is indicated in response to the end of start-up operations.

CHAPTER 2 BASIC OPERATIONS

B. Printing

1. Processing on the Computer Side

In response to a print command from the user, the application program sends image data to the

printer drive with the help of the operating system.

The printer driver then translates the image data and the printer settings information into PostScript commands. The print data described in the page description language (i.e., PostScript) is sent to the printer board through the parallel port or the network port depending on the type of connection used between the printer board and the computer.

The printer driver for the printer board is stored on the CD-ROM that comes with the board.

2. Processing on the Printer Board Side

The print data input block of the printer board serves to send print data from the computer to the print data processing block using the selected type of connection. In response, the print data processing block generates image data from PostScript print data so that the copier can print it.

When data is ready for transmission to the copier, the image data output block sends it to the copier on a page-by-page basis.

CHAPTER 2 BASIC OPERATIONS

III . TRANSFERRING PRINT DATA

The printer board provides a parallel interface on a network interface for connection to a

computer. Both these interfaces may be used concurrently.

A. Connecting to the Parallel Port

The parallel port is designed to comply with IEEE1284 (commonly known as "bi-Centronics" standards). It supports an existing Centronics interface, a nibble interface (in which data is sent to the computer in 4-bit units), and an ECP (Enhanced Capability Port) interface (in which data is exchanged in both directions in 8-bit units at a high speed).

Reference:

CHAPTER 2 BASIC OPERATIONS

B. Connecting to a Network

1. Outline

The printer board comes standard with an interface for an Ethernet network; i.e., it provides an

AUI connector for 10Base5, and an RJ-45 connector for 10/100Base-T.

In the case of 10Base5, connect an AUI cable to the AUI connector. The AUI connector and the RJ-45 connector are connected as a network port and, therefore, cannot be used concurrently. (Do not connect cables to both connectors at any time.)

The 100Base standards supported by the printer board are 100Base-TX. The printer board is equipped with a function that automatically switches between 10Base-T and 100Base-TX, capable of operation on a network on which both speeds are used. (Select 'Auto Detect' under 'Ethernet Speed'.) If auto detection fails to operate on a HUB equipped with a 10Base/100Base auto switch, advise the network supervisor to select a fixed speed.
