I. FEATURES

1. Accommodates the PCL5e and PCL6 PDL as standard.

The Network Printer Board-J1 package is designed to accommodate the PCL5e and PCL6 PDL (Page Description Language), developed by Hewlett-Packard Company, as standard.The Network Printer Board-J1 package is capab le of decoding instructions written in these languages for printing on a digital black-and-white copier.

2. High-speed print processing by a high-performance CPU.

The high-speed CPU (Intel i960: 32-bit RISC type microprocessor.) with an access clock frequency of 33 MHz processes printing information at a very high rate.

3. Multiple memory sizes.

An 4 MB memory comes standard with the Network Printer Board-J1 package for use as a buffer f or print data from e xternal devices.Adding a SIMM to the memory will expand the capacity to as high as 20 MB, thereby decreasing memory overflow and enabling smooth processing otherwise occurring when complex data from external devices is processed.

4. Share the Network printer in Multi-Protocol Network Environment.

The Network Printer Board-J1 package fits multiple network operating systems (such as Novell NetWare and Windows NT), It can set up the network printer to service print jobs from one or All platforms.

5. Disable the Energy saving mode.

Energy saver mode does not operate when the networ k Pr inter Board-J1 is installed.

CHAPTER 1 GENERAL DESCRIPTION

II. OUTLINE OF THE PRODUCT

The Network Printer Board-J1 package serves as an interface between a copier and external device (host computer, for example) via Ethernet (10Base-T). Decoding data from the host-computer for generation of video signals for printing on paper.

The package is capable of decoding PCL6 and PCL5e developed by Hewlett Packard Company.

IV. OPERATION

Once the Network Printer is installed the PRINT/SCAN button on operation panel will

become enabled.

Figure 1-401

When the PRINT/SCAN button is pressed, the following screen is displayed on LCD

display panel with ON LINE mode displayed.

Figure 1-402

ON LINE Use the ON/OFF button (F4) to switch the printer off line and on line.You

have to switch the printer off line before you can open the PRINTER MENU to perform a test print and other procedures.

A. Printer Menu

The following pages describe the Printer settings which can be accessed via the print

menu.

CONTINUE Some error that interrupt printing can be skipped. For example, if the

paper size specified by the application software program is not loaded in the paper cassette an error message will ask you have to load the correct paper size in the cassette. To skip this error, all you have to do is select the CONTINUE item in the PRINTER MENU.

FORM FEED This procedure prints data remaining in the receive buffer on the PCL

board. This may occure if the application software program does not send form feed (FF) or if the printer is taken off line during a print job.

RESET

JOB CLEAR This procedure is to cancel a print job. After you cancel a print job, the

unprinted portion of the pr inter job is deleted.

PRINTER This procedure is to cancel the current printer settings and restore the

defaults.

PCL BOARD This procedure performs a hard reset for the PCL board.Perfor m a hard

reset if the PCL board hangs up.

TEST

TEST PRINT This procedure is to perform a Test pr int. The Test print performs three

important tasks that confir m the printer is operating correctly:*

1. Listing all menu settings.

2. Printing a variety of patterns.

3. Listing other important information like RAM size, version and revision numbers.

FONT LIST This procedure pr ints a list of the inter nal fonts.**
