General Information

The Phaser 540 Color Printers

The Phaser 540 and Phaser 540 Plus Color Printers both combines a color laser, continuous-tone print engine with an image processor supporting Adobe’s PostScript Level 2 page description language (version 2015). The image processor features a bi-directional parallel interface for host communication. Optional network adapter cards to the image processor allow the printer to communicate on networks using LocalTalk, serial, Ethernet or Token Ring protocols. The Ethernet network card supports EtherTalk, Novell and TCP/IP. With the Token Ring network card, the Phaser 540 Plus supports Toten Ring protocols. The network cards are sometimes referred to as “smart cards” because each houses its own processor for executing speciﬁc on-board protocols; only data is transferred from the installed smart card to the printer’s image processor board.

The printers each comes standard with 20 Mbytes of RAM which can be supplemented with one or two additional 16-Mbyte RAM SIMMs. The printer contains 39 standard, built-in fonts. The printer features a SCSI-compatible interface to connect to an external hard disk drive for additional font storage. An orderable option, the Phaser CopyStation can also be connected to the printer’s SCSI port to give the printer the ability to optically copy color images.

The printer supports printing on A- and A4-sized paper and transparency ﬁlm from an A or A4-size tray. An optional two-tray second feeder (called the Lower Tray Assembly) is available. The printer also supports manual feeding. The Phaser 540 Plus also supports Legal-size paper in its Legal-size tray.

The printer prints at a user-selectable resolution of 300 dots-per-inch or 600 dots-per-inch. Color printing is at either 4 or 16 levels of color depending on the amount of memory installed in the printer. After being idle for one hour the printer switches into its Energy Star mode where it consumes less than 45 watts of power. It “awakens” upon receiving data at any of its ports. The printer also features a closed-loop image density sensor system that allows it to auto-calibrate its color imaging so printing output remains consistent over the life of the print engine and its consumable supplies.

RAM and printer capabilities

With additional RAM memory the printer’s capabilities increase:

■

With standard 20 Mbytes of RAM, the printer has a frame buffer of 16 Mbytes, an I/O buffer of 100 kbytes, an image pipeline color cache of 500 kbytes, and PostScript virtual memory of 3.6 Mbytes. With standard 20 Mbytes of RAM, the printer can print 300 dpi continuous-tone and 600 dpi bi-level images.

1-2

Phaser 540 Color Printer

With 36 Mbytes of RAM, the printer has a frame buffer of 32 Mbytes,

■

an I/O buffer of 100 kbytes, an image pipeline color cache of 500 kbytes, and PostScript virtual memory of 3.6 Mbytes. With 36 Mbytes of RAM the printer can print 300 or 600 dpi continuous-tone images and has faster data throughput. With the additional RAM in the Phaser 540 Plus, the scan-to-print start time of the Phaser CopyStation is reduced to about 65 seconds.

■

With a maximum 52 Mbytes of RAM, the printer has a frame buffer of 32 Mbytes, an I/O buffer of 1 Mbytes, and image pipeline color cache of 2 Mbytes, and PostScript virtual memory of 16.8 Mbytes.

General Information

Health LED

A health LED indicates the status of the image processor board. The health LED is mounted on the image processor board and is viewable through the grill behind the manual feed tray. (The grill is the removable RAM SIMM options cover.) Once the PostScript code is loaded into memory and the image processor is initialized and running, the image processor blinks the LED at a one-second rate.

Blinking (at a steady rate): The printer is operating normally. The LED

■

blinks irregularly during power-up self-diagnostics.

If a soft error occurs, the image processor board operates, but in a reduced capacity. Soft failures include failure of expansion memory SIMMs or any of the interface ports. When a soft error occurs, the printer automatically prints a startup page listing the error.

■

or Off : A hard error condition has occurred that would keep the

image processor board from operating.

Media tray type sensing

The combinations of the three tray sensors “tell” the print engine what type of paper tray is installed. The tray sensors are located on the left-side interior of the paper tray slot. Sensor actuators are attached to the bottom end of the tray to close the appropriate sensor. There are four tray types:

■

Letter (A-size) paper

Letter (A-size) transparency ﬁlm

Chapter

Installing the Printer and Drivers

This chapter discusses installing the printer and its drivers as a part of the S0 printer installation option. Tektronix Service Option S0 consists of three main functions detailed in this and the next two chapters of this manual:

■

Chapter 2 “Installing the Printer and Drivers.” The ﬁrst portion of installation instructions, this chapter, consists of ﬁve basic processes:

Pre-installation interview. This is a phone interview to verify that the

■

customer is ready for the printer. The interview veriﬁes that the customer has a suitable place for the printer with the proper environment. The call also veriﬁes that any assistance, such as network system administration, will be available for the scheduled installation and that all necessary cables will be available.

■

Unpacking. This is the procedure for taking the printer out of its shipping box.

Testing. This checks that the printer works properly prior to connecting

■

it to a host computer.

Cabling and conﬁguring. This discusses setting up the printer for

■

communicating to the appropriate host computers.

■

Loading drivers. This covers installing software on the host computers and conﬁguring the host applications to drive the printer.

Following these steps, proceed to Chapter 3 and then Chapter 4.

■

Chapter 3 “Verifying the Printer and Host Connections” explains how to verify that the printer, the host driver and the connection between them functions correctly.

■

Chapter 4 “Key Operator Training” gives a procedure for training the customer to use and care for the printer.

Cabling the printer

Note

This topic explains making a hardware connection between the printer and its host computer, setting the communication parameters for the printer's serial and parallel ports to be compatible with the user's host computer and driver installation. This topic is divided into three main parts: Macintosh, PC, and workstation.

Carry spare serial and parallel cables. You can use them if you

encounter a defective cable or as an alternate means of testing the printer-to-host communications.

Connecting the printer to a Macintosh

A direct connection between the printer and a Macintosh is through the printer's serial port. Since this is a highly unlikely connection for a customer to use because of the serial port’s slow data speed, it is not discussed. A networked connection for a Macintosh will most likely be either a LocalTalk network or an Ethernet network.

LocalTalk connection to a Macintosh

Note

For a LocalTalk network, the Serial/LocalTalk network card must be installed.

Turn off the printer. LocalTalk protocol requires you to attach the LocalTalk cable with the printer powered

For a LocalTalk network connection, attach the network adapter to the printer's LocalTalk port. Then attach the network cable (LocalTalk cable, PhoneNet, etc.) to the network adapter.

Phaser 540 Color Printer

Turning on the printer

The startup page

When you turn on the printer, it executes a series of self-tests to determine if there are any problems with the PostScript interface. After running self-tests, the printer prints a startup page if it has not been disabled. After running self-tests and printing the startup page, the printer is ready for operation. A front panel menu item allows you to enable or disable the startup page.

The startup page provides you with valuable information about the printer:

■ Printer name

■ Fonts

■ Ports (serial, parallel, LocalTalk, Ethernet, Token Ring)

■ Ethernet protocols

Installing the Printer and Drivers

■ TekColor corrections and print quality mode

■ Pages printed

■ RAM installed

■ Tektronix version ﬁrmware level

■ Print engine ﬁrmware level

■ Adobe version software level

■ Printer SCSI ID

The conﬁguration page

To provide further diagnostic information, the printer is able to print a conﬁguration page. The conﬁguration page lists the values the printer stores in its NVRAM. These values can be informative when troubleshooting the printer, particularly networked operations. Refer to the Chapter 6 topic “Printing the conﬁguration page” on page 9-4 for details on printing the conﬁguration page. A downloadable PostScript utility, found on the Drivers and Utilities diskette, also allows you to print the conﬁguration page.

The conﬁguration page gives you the following information:

■ General information about the printer, such as page count, the

programmed name, Ethernet address, the TCP/IP authorization code (if loaded), timeouts, number of fonts, and total memory

■ Color settings such as Finepoint and Vivid Color.

Driver and communication set up

Loading the Macintosh driver

The printer uses the Adobe PostScript Level 2 language. To take advantage of the Level 2 features, Tektronix developed the Tektronix Phaser 540 driver, which appears in the Chooser along with the LaserWriter 7.0.x or 8.0x driver. The Phaser 540 driver includes special paper sizes and TekColor color correction options. Refer to the Phaser 540 Drivers and Utilities Printing Reference for more details on the Tektronix drivers.

To install the Tektronix driver with system 6.0.7 or higher

Restart the Macintosh with the Shift key held down until the message Extension off is displayed on the screen. This disables any anti-virus software.

Place the Phaser Macintosh Printer Driver and Utilities diskette into the disk drive.

Double-click on the Installer icon.

Follow the directions on the screen to complete the driver installation.

If you are using system 6.0.7, the LaserWriter 7.1.2 software and its support ﬁles (Laser Prep, Backgrounder, and PrintMonitor) are required to use the Tektronix driver and to print in the background. To install this software:

Open the folder Old System Items in the Macintosh Driver and Printer Utilities diskette.

Drag the ﬁles Backgrounder V1.3 and PrintMonitor V7.0 from the diskette to the closed System Folder on the Macintosh’s hard disk. At the alert message, click OK to automatically install these ﬁles in their proper folders.

Restart the Macintosh.

Select the driver’s icon and the printer in the Chooser.

The Phaser Share software and utilities diskette contains an LaserWriter Utility ﬁle you can use to reprogram the printer to reside in another EtherTalk zone, if necessary.

The Printers dialog box should still be displayed; if not, double-click the Printers icon in the Control Panel.

Choose your printer from the list of installed printers.

Choose the Set As Default Printer button if you want to select your printer as the default.

Choose the Connect button; the Connect dialog box appears.

Select the port the printer is connected to. Your printer is connected to your computer through one of the computer's communications ports. You need to tell the driver which port your printer uses so the driver can print your documents.

The two main types of communications ports are parallel ports and serial ports; your computer may have one or more of each. Generally, your printer is connected through LPT1: if it is connected to a parallel port, or through COM1: if it is connected to a serial port. If you have multiple ports, your printer may be connected to another, such as COM2:.

Note

The printer’s conﬁguration page contains the information you need to set up the printer’s port.

The port FILE: lets you write a PostScript document to a ﬁle instead of to the printer. For more information about communication ports, refer to your Windows documentation.

Set the Time-outs. These options regulate your computer’s communications with its printer ports.

■ Device Not Selected: (For parallel – LPT – ports only) Type a value of

0, or between 15 and 999, in this text box to change the number of seconds Windows waits before notifying you that a printer is off-line. The default is 15 seconds.

■ Transmission Retry: Type a value between 45 and 850 in this text box

to change the number of seconds Windows waits after a print job has begun sending characters to the printer before sending an Alert message that the printer is no longer accepting data. The default setting is 45 seconds. When using the Print Manager with a shared printer, you should set this option to a larger value, such as 600 (10 minutes) to avoid the Alert message when printing multiple page documents.

Choose the OK button to return to the Printers dialog box, then choose the set up button. A dialog box appears with the name of the printer you selected across the top. Use this dialog box to select paper source, paper size, and image orientation.

Updating the standard Microsoft Windows PostScript driver

If a customer prefers to use the standard Microsoft Windows PostScript printer driver instead of the Tektronix driver for Windows, follow these instructions. This update procedure provides printer page size information for applications within Windows using the standard driver. However, color adjustments and other PostScript Level 2 features are available only with the Tektronix Windows

3.1 driver and are not supported by the standard driver.

These instructions assume a basic familiarity with Windows operation and terminology. For additional information about Windows, refer to your Microsoft Windows documentation.

Update procedure

Note

Phaser 540 Color Printer

Printers using the Tektronix driver for Windows have (TekColor) listed in their name. Printers without this designation are using the standard Microsoft Windows PostScript driver and the WPD ﬁle.

When prompted, insert the Tektronix–provided Windows 3.1 Printer Driver diskette into your computer’s disk drive. Choose your printer (without (TekColor) after the name) then click the OK button. When asked to insert a disk with the updated PSCRIPT.DRV ﬁle, enter system as the location so the current PSCRIPT.DRV ﬁle is used.

Installing the printer driver for OS/2 Version 2

Under OS/2 Version 2.0 printing is managed through printer object icons. Object icons represent a printer set up, and are associated with a port, a driver, and a queue, if appropriate. These object icons replace the earlier Print Manager functions. Normally, a printer object icon is installed during the initial OS/2 2.0 installation. A single printer object on the desktop may represent more than one printer. A printer object on the desktop is a “generic” object that can be conﬁgured to point to any printer by changing settings in the settings notebook for this object. You may not have more than one printer object pointing to the same I/O Port. Port designations for each printer object must be unique. Before new printers are installed, existing printer object assignments must be changed.

Installing the Printer and Drivers

Note

For parallel port connections, check existing printer object port assignments before installing a new printer to be sure there is no conﬂict. Once you are familiar with existing printer objects (drivers and ports associated with these objects) you can install a new printer.

In the procedure below, the printer remains associated with LPT1, and you will set up a new printer object for LPT2. Following are the steps to create the LPT2 PRINTER object:

IBM suggests that printer objects be named to represent available printer ports rather than printer names or printer drivers. This avoids the confusion of a speciﬁc printer name being associated with an object that is using a driver for a different printer.

Check all existing printer objects to be sure that they do not point to LPT2. Make any necessary changes to the settings for these printer objects.

Locate the original OS/2 Print Driver Diskettes (numbered 1-5).

Find and open the Templates folder and locate the Printer Template.

Using the mouse, point to the Printer Template, hold down the right mouse button, drag the object onto the desktop, and release the mouse button.

The Create a Printer dialog box will be displayed. In the name ﬁeld, type: LPT2 PRINTER. This is the only opportunity to assign this name and it cannot be changed. The ﬁrst 8 characters (except spaces) will display in all printer selection menus, so the printer will be listed as LPT2_PRIN.

Installing the Printer and Drivers

Scroll through the printer drivers listed to locate the proper Tektronix printer driver name. Select it then click Install from the menu options.

In the Install New Printer Driver dialog box, click on the button according to the driver shipped with OS/2. If necessary, set the directory to B: and insert the Printer Diskette #1 in drive B:. Click on Refresh. The system searches the diskette for driver groups and prompts you to stop the search or continue. When the PostScript driver (PSCRPT.DRV) appears, stop the search.

A list of possible PostScript printers are displayed for your selection. Using the scroll bars, move down through the alphabetical listing until you ﬁnd the selection PSCRIPT.Tektronix Phaser 540. Click on the correct printer name and then click on Install. The system will install your printer driver. Click OK.

Close the Install New Printer Driver dialog box. Before leaving the Create a Printer dialog box, adjust the printer port time-out setting.

Double-click on the port you have selected, in this example, LPT2. Change the time-out to 180 seconds. Then click OK.

To create the new printer object on the desktop, click Create; a new printer driver object is placed on your desktop. Conﬁrm and adjust the settings for this printer driver by performing the following steps.

Bring up the Settings Notebook by clicking the right mouse button on LPT2 PRINTER. Click on SETTINGS.

Select the Printer Driver Tab. Conﬁrm that the Tektronix Phaser 540 is selected (highlighted). Double-click on the Phaser 540 driver to conﬁgure the Printer Properties. This is where you can deﬁne printer paper sizes and orientation. These settings can be adjusted from within software applications as well. To get started, set Forms to A-size paper; this is the recommended setting. Next, select Device Defaults, set Form to A-size and set Orientation to Landscape. One of the most likely causes of printer errors is that the document and device defaults do not properly match.

Using

printcap

to conﬁgure a workstation for the printer's serial port

The printcap ﬁle conﬁgures the workstation's lpr queues. The ﬁle is usually found in the workstation's /etc. directory. The printer's rear panel switch settings should all be down. Use a null modem cable since the printer is set up as a DTE device. For this example, the printer's serial port settings are as follows:

Speed: 9600 Flagging: Software (XON/XOFF) Data Bits: 8 Parity: Ignore

To set up a printcap entry, perform the following steps:

Make a backup copy of the /etc/printcap ﬁle.

Append to the printcap ﬁle a new print queue name and set the port parameters as needed. Append the following to the printcap ﬁle:

px:\

:br#9600:rw:\ :fc#00000374:fs#00000003:\ :xc#0:xs#0040060:\ :mx#0:sf:sh:\ :sd=/var/spool/px:\ :if=/var/spool/px/if:\ :lp=/dev/ttya:

px may be changed to whatever unique printer name you choose. The device driver name in lp may be different depending upon which serial port the printer is connected to and the device driver naming scheme for the workstation.

Create a directory called /var/spool/px and create a ﬁle in the directory called if. The content of the ﬁle should look like this:

#!/bin/sh /bin/cat

Give the if ﬁle executable permission:

chmod +x if

Conﬁguring a Novell NetWare server for the printer

This is a brief overview of the steps you follow to conﬁgure a Novell NetWare ﬁle server and set up print queue to support the printer on a Novell network. The Phaser Share Software User Manual gives the step by step procedure you follow to perform this conﬁguration. There are two methods, each using a different utility program, you can use to conﬁgure the ﬁle server and set up print queues. In brief, this is what you will do:

Load the utility Advanced Conﬁguration Tool (ACT) onto the ﬁle server through a workstation.

Log on to a ﬁle server as supervisor with supervisor privileges.

Run ACT and select Quick Conﬁguration.

At this point you will be able to “see” a list of available printers. The printer’s print server name is displayed. The default name is TEKxxxxxx where xxxxxx is the last six hex digits of the printer’s Ethernet address. Select the printer. If the printer is not displayed, refer to the Novell NetWare Conﬁguration topic in the Phaser Color Printers Network Manual.

Select a ﬁle server for the printer to service.

Select a queue for the printer to service or create a new queue.

Save the conﬁguration.

Following this, you can select another ﬁle server and create more queues for the printer to service. You can have a total of 32 queues on up to eight ﬁle servers.

2-30

After all ﬁle servers have been conﬁgured, save the conﬁguration ﬁle and restart the print server.

Phaser 540 Color Printer

Alternately, you can use a utility called PCONSOLE to perform the same conﬁguration. However, using PCONSOLE, you will not “see” and select the printer on the network as you did in Step 4. Instead, you must enter the print server name (TEKxxxxxx) of the printer as it is shown on the printer’s conﬁguration page. (Refer to the topic “Printing the conﬁguration page” on page 9-4 for details on printing the conﬁguration page.)

Conﬁguring TCP/IP on a UNIX host

This is a brief overview of the steps you follow to conﬁgure the host and the printer for TCP/IP network. The Phaser Share User Manual gives the step-by-step procedure you follow to perform this conﬁguration. You will ﬁrst conﬁgure the host and then the printer.

Conﬁguring the host

Add the printer name to the host table (/etc/host) and assign an IP address to the printer’s name.

Assign a print queue to the printer by editing the /etc/printcap ﬁle.

Installing the Printer and Drivers

Conﬁguring the printer

Authorize the TCP/IP protocol. This will have already been done at the factory if the Option P2 was purchased with the printer. For a TCP/IP protocol ﬁeld upgrade you will have to perform this procedure at the customer site. This is done locally through the parallel port.

Set the printer’s IP address. This is done remotely from the host. You manually execute a script that creates a PostScript ﬁle which you will send to the printer to load the IP address into the printer’s NVRAM. Alternately, you can create a RARP or BOOTP conﬁguration ﬁle to automatically conﬁgure the printer’s IP address (although it will not be stored in the printer’s NVRAM).

Optionally, conﬁgure the printer’s TCP/IP parameters:

■ lpr, the host access table (if the customer site uses lpr).

■ AppSocket, the printer language(s) supported by the printer (if the

customer site uses AppSocket).

■ Syslog, collect printer information for the network administrator.

■ SNMP, allow the administrator to query and control the printer’s status

remotely.

Novell NetWare veriﬁcation

NetWare is a shell program running above DOS. Generally, in a Novell network, a ﬁle server, which looks and acts much like a PC, maintains queues for the print ﬁles created and sent for printing from other workstations on the network. The Phaser 540, in turn, ﬁnds all ﬁle servers with Phaser 540 queues and extracts the print ﬁles from them. You must determine if a PC can send a print ﬁle to the ﬁle server.

As outlined in the Section 2 topic, “Conﬁguring a Novell NetWare server for the printer” on page 2-30, the ﬁle server and printer are conﬁgured during the printer installation using software such as Advanced Conﬁguration Tool (ACT) or PCONSOLE. The ﬁle server is given a name and conﬁgured with queues for the printer.

Send a print ﬁle to the printer

Log into a ﬁle server from a NetWare workstation to gain printer access.

Verifying the Printer and Host Connections

Type:

CAPTURE NB NT NFF Q=<queue name> L=1

Use any text editor to create the following two-line, text-only print ﬁle. %!

showpage

Copy the print ﬁle to LPT1 using this syntax: copy <ﬁle.nam> LPT1:

where <ﬁle.nam> is the name of the print ﬁle.

The printer should load and then eject a blank sheet of paper.

If the print ﬁle does not print, verify that the printer has been set up to service the queue. Also verify that the password set for the printer (if one was set by the administrator), is the same as that used for the print server. Ensure that the Ethernet frame type the printer is using is the supported by the ﬁle server. Finally, make sure that the correct language is being used by the printer to interpret the incoming print ﬁle; this is indicated on the printer’s conﬁguration page. For additional information, refer to the Troubleshooting chapter of the

Phaser Share Network Cards and Printer Management Software User Manual.

Verifying the Printer and Host Connections

Once you are able to send a print ﬁle to the printer, launch an application on one of the Novell networked workstations and print to the printer’s queue.

Using the Error Handler utility

If a PC has trouble printing directly to the Phaser 540, download the Tek Error Handler utility ﬁle to the printer. The Tek Error Handler (TEKEHAND.PS) is for PostScript Level 1 and Level 2 printers.

Locate the TEKEHAND.PS ﬁle in the PHSR540 directory on the Printer Utilities diskette.

Copy the ﬁle TEKEHAND.PS to the PC's hard disk or use the ﬁle from the diskette.

Use the DOS COPY command to send the ﬁle to the printer. For example: COPY ﬁlename LPT1:. If necessary, substitute the appropriate port for LPT1:

Verifying the Printer and Host Connections

Workstation veriﬁcation

Verifying connection and printing using TCP/IP protocols

The printer accepts ﬁles from networked UNIX and VMS workstations using TCP/IP communications. The printer supports BSD UNIX 4.3, AT&T's UNIX System V with BSD 4.3 lpr extensions, and DEC VMS with Tektronix PhaserSym software. The printer conforms to Ethernet IEEE 802.3 network speciﬁcations.

UNIX

To verify the host-to-printer (UNIX host) connection, execute the ping command from the host. If ping does not work, the printer or host has not been properly conﬁgured, or there is a cabling problem

To print to the printer from the host, you must ﬁrst have the printer’s queue established. This is site-dependent and requires the aid of the site’s network administrator. Once the queue is in place you can proceed to the next step.

Send a print ﬁle to the printer using the following syntax:

lpr -P <queue name> <ﬁle.nam>

The queue name was established earlier in Step 3. The print ﬁle <ﬁle.nam> can be any PostScript print ﬁle. To keep things simple, you should send a simple ﬁle such as the one of the utility ﬁles included in the software diskettes such as conﬁg.ps which causes the printer to print out its conﬁguration page.

If the page prints, out then both the printer, printer queue and the network connections are working correctly. If the print ﬁle cannot be sent, then a problem probably exists in the print queue set-ups for the printer, since ping was veriﬁed in Step 1. You and the network administrator should repeat the TCP/IP installation as outlined in the printer’s Phaser Share user manual.

Service Manual

3-9

Verifying the Printer and Host Connections

VMS

To print to the printer in the VMS environment, you must have the PhaserSym symbiont running on the host. To print to the printer from the host, you must ﬁrst have the printer’s queue established. This is site-dependent and requires the aid of the site’s network administrator. After the queue is in place you can proceed to the next step.

To verify the host-to-printer (VMS host) connection, use the NCP LOOP CIRCUIT command from the host. If this does not work, the

printer or host has not been properly conﬁgured, or there is a cabling problem

From the host, issue the SHOW QUEUE /full command to list all the available printer queues. Ensure that the Phaser 540’s queue is listed.

Print to the printer by sending this command:

where <queue name> is the printer queue and <ﬁle.nam> is any PostScript ﬁle. If the ﬁle does not print, the print queue has not been conﬁgured properly.

print/queue=<queue name> <ﬁle.nam>

Using the Error Handler utility

If the workstation print ﬁle does not print on the printer, (the ﬁle downloads without an error but no print is ever made), then download the Tek Error Handler utility to the printer.

Locate the TEKEHAND.PS ﬁle in the PHSR540 directory on the Printer Utilities diskette.

Copy the ﬁle TEKEHAND.PS to the workstation's hard disk or use the ﬁle from the diskette.

Send the ﬁle to the printer.

This loads the error handling utility into the printer's memory where it remains until the printer is turned off. Send a print ﬁle to the printer as explained in the previous procedure. If an error occurs, it will print a page listing the error.

Loading media

Paper/transparency: Demonstrate how to load paper or transparency ﬁlm into

a paper tray.

■

Before loading paper into the tray, there are a few factors to consider:

Key Operator Training

Emphasize to the customer not to touch the printing surface of the media; handle it by the edges only. Fingerprints can affect print quality.

Explain that the customer should not bend the media (especially transparency ﬁlm) too sharply. Otherwise, print quality may be affected.

Demonstrate fanning the media (especially transparency ﬁlm) prior to installing it in the paper tray.

Show where this is explained in the user manual.

Paper grain: short or long

■

Grade, weight and thickness:

Bond: 61 to 90 g/m

■

(16 to 24 lbs.)

Follow these guidelines when you make transparencies:

Use only Tektronix transparencies .

■

Be sure to load transparencies with the printing side up.

When using the tray, load the transparencies so that the notched end

■

of the transparency is in the lower-right corner of the tray. The notched end should be next to the load level decal inside the tray, near the paper backstop.

When using manual feed, insert the transparency ﬁlm so that the

■

notched end goes in ﬁrst toward the back of the printer.

Show where this is explained in the user manual.

■

For manual feeding, wait 5 seconds after the ﬁrst sheet enters the printer before manually inserting a second sheet.

Explain to the customer not to re-use media that has been processed through or jammed inside the printer; damage to the printer may result. Also, do not print double-sided prints; it will shorten the life of the imaging unit and can damage paper path components such as the pick rollers paper feed rollers and sensors.

and clear a printing jam.

■

Show where this is explained in the user manual.

Explain to customers that any time a print has passed by the transfer

■

roller but before it reaches the fuser, it has unfused toner adhering to it. In these cases where jams occur, the sheet of media should be removed by ﬁrst removing the imaging unit, and then continuing to pull the sheet of media forward through the transfer roller. Under no circumstances should a sheet of media with toner on it be pulled backward past the transfer roller. This contaminates the transfer roller and aligning rollers with toner.

Key Operator Training

Cleaning

Exit (exit jams): Show customers how to open the right cover to access and clear

an exit jam.

Show where this is explained in the user manual.

■

Explain the importance of keeping the printer clean. Emphasize how dirt and dust can affect print quality and paper-pick reliability.

■

Demonstrate how to clean the pre-transfer corona with the cleaning tool.

■

Show customers how they can use a plastic, squeeze-type, suction bulb to blow air to clean the image-density sensors and the accumulator belt home-position sensor. A swab is provided with each new imaging unit; demonstrate how to use it to clean the sensors. Be careful not to brush clothing against the toner cartridges’ developer roller.

Theory of Operation

The toner cartridges

Four toner cartridges, black, yellow, cyan and magenta, contain the primary color toners that are sequentially transferred onto imaging unit’s photoconductive belt depending on where the laser exposed the belt. Subsequently, the toner is transferred to the imaging unit’s accumulator belt from which it is transferred to a sheet of media.

The fuser

The fuser permanently bonds the toners to the media through a combination of heat and pressure.

The engine boards

Working as the “brains” of the print engine, the engine control board coordinates all printer functions. It contains the microprocessor and ROM that control printer operations. The engine driver board drives the printer’s motors and solenoids.

The power supply

The power supply provides regulated DC power source for the printer’s electronics, motors and high-voltage chargers and bias rollers.

The mechanicals

Mechanicals include the motors and solenoids that drive the belts and rollers of the printer.

The image processor board

The image processor board converts the image data from the host computer into a raster format for the print engine.

Laser imaging

Overview

The laser printer prints an image on paper using a technique called laser

electrophotography

Discharge Area Development or “write black.” In this process, a digitally modulated laser, scans laterally across a negatively charged, rotating photoconductive belt. Where the belt is exposed by the laser beam is where the image is written and toner is transferred.

In the color print process, the photoconductive belt rotates past the laser scanner and the toner cartridges four times, once for each primary color and black. During each sucessive pass, the laser exposes the portions of belt that correspond to the primary color’s component of the image. Toner is attracted to the laser-exposed portions of the belt. As the photoconductive belt rotates it passes the accumulator belt. As the name implies, the accumulator belt accumulates or picks up each primary layer of toner from the photoconductive belt and holds it, layer upon layer, until it contains the entire image. At this point, a sheet of paper is advanced past the accumulator belt and the toner is transferred to the sheet of paper. The paper advances to the fuser where heat and pressure permanently bond the toner to the paper. From the fuser, the paper is driven to the output tray.

. The printer uses the electrographic process known as

A photoconductive belt cleaning blade scrapes residual toner off of the belt before the next primary color’s toner is applied to the belt. This prevents each toner from contaminating the next color’s layer. The cleaning blade is in constant contact with the belt. An accumulator belt cleaner scapes residual toner off of the accumulator belt. This prevent an image from one print contaminating or ”ghosting” on the next print. The blade only comes in contact with the belt once the accumulated toner layers are transferred to the sheet of paper.

Theory of Operation

Pre-exposure

The print process begins when the photoconductive belt passes by the pre-exposure lamp. The belt is moving at a speed of 96 mm-per-second for 300 dpi printing or 48 mm-per-second for 600 dpi printing. The light of the pre-exposure lamp, which is a horizontal row of red LEDs, removes random negative charges from the photoconductive belt. Before pre-exposure, the surface of the belt varies from -500 volts to +50 volts. Following pre-exposure, the voltage level of the illuminated portion of the belt only varies from 0 to +50 volts. The pre-exposure lamp is sometimes called the erase lamp since it “erases” negative charges from the belt.

Electrostatic charging

The electrostatic potential of the belt is not uniform following pre-exposure. As the belt rotates, it passes a scorotron charger which bombards the belt with negative charges. The scorotron charger behaves somewhat like a vacuum tube. The grid of the charger, held at a potential of between -500 volts (for 600dpi printing) to -520 volts (for 300 dpi printing) and coupled with the varying voltage potential on any discrete point on the belt’s surface, determine how many electrons can ﬂow from the corona wire onto that point of the belt’s surface. The corona wire is charged to -6 kvolts with a constant current of

400 varying charge of the belt surface, results in a uniform negative potential on the belt surface of -500 volts or -520 volts, depending on the selected dot-per-inch printing.

Theory of Operation

Laser exposure

As the photoconductive belt rotates, the uniformly charged portion of the belt is exposed by the modulated laser beam. As the belt passes vertically in front of the horizontally scanning laser beam, negative charges on the belt surface are neutralized where exposed by the beam. This forms a latent image on the belt. The laser beam is turned off for “non-written” portions of the image.

The power of the laser beam is varied from 0.5 mW to 0.7 mW depending on whether the printer is printing in 600 dots per inch (dpi) mode or 300 dpi mode. Additionally, the duty cycle of the beam, for each dot, is varied from 70% to 0 to achieve grayscale printing. Following laser exposure, the negative potential of the belt varies in steps from -500 or -520 volts (unexposed) to -50 volts (fully exposed).

Laser scanner

The laser beam selectively neutralizes some of the negative charges on the belt surface.

The laser scanner

Lenses and mirrors in the laser scanner direct the beam at the photoconductive belt. The beam originates at a laser diode. The beam is made parallel by the collimator lens and is directed at the rotating polygonal mirror. The mirror rotates at a constant 11,500 revolutions per minute. This transforms the beam into a horizontally scanning beam, which is directed through a fwhich alters the beam’s angular rotation motion into a constant horizontal motion. The beam then passes through a toric correction lens, which corrects the beam for any vertical misregistration. The beam then reﬂects off of a mirror and passes through a window where it scans across the rotating photoconductive belt. At the beginning of each of its horizontal sweeps, the horizontal sync mirror deﬂects the laser beam to the horizontal sync sensor. This alerts the engine control board that the laser beam is beginning its horizontal sweep and that it can begin to modulate the signal for the data to be printed on that line of the image.

Toner pickup (development)

As the photoconductive belt continues to rotate, it passes by one of the four toner cartridges. Each cartridge is selectively cam-driven forward to bring its developer roller into direct contact with the belt when it is that cartridge’s turn to transfer its toner to the belt during the belt’s four rotations past the cartridges. The currently activated toner cartridge’s developer roller is charged to a potential between -80 to -350 volts. Toner is attracted to the exposed portions of the belt in reverse proportion to the amount of negative charges left on the belt. Since the charge on the fully exposed portions of the belt is at least near -50 volts, the greatest amount of toner is transferred. Where the negative charges are greater at the lightly exposed or unexposed areas, less or no toner is transferred. The developer roller rotates at 1.6 (300 dpi printing) or 2.13 (600 dpi printing) times the speed of the photoconductive belt to ensure a constant supply of toner. As the belt advances, it passes the pre-transfer lamp which, like the pre-exposure lamp, removes remaining negative charges from the unexposed portions of the belt.

Toner transfer to the accumulator belt

As the photoconductive belt rotates, it comes in contact with the accumulator belt, which rotates at the same speed. The ﬁrst bias transfer roller, located under the accumulator belt at the contact point with the photoconductive belt, carries a charge of +500 volts. This strong potential attracts and holds the toner from the photoconductive belt to the accumulator belt. The accumulator belt rotates four times so it can pick up or accumulate each of the four toner layers, one layer on top of the last. An accumulator belt home-position sensor sync signal, generated from a timing mark on the accumulator belt, informs the engine control board that it is time to begin exposing the next toner layer’s information onto the photoconductive belt. When that happens, the accumulator belt is rotated in the proper position to transfer the toner layer in proper registration with the previous layer(s).

As the accumulator belt rotates, it passes the pre-transfer charger. The charger ﬂoods the toner and belt with a uniform layer of electrons to give the toner a strong negative charge; this will improve transfer of the toner to the paper. Any toner remaining on the photoconductive belt after the transfer to the accumulator belt is scraped off by the photoconductive belt cleaning blade, which is always in contact with the belt. This leaves the photoconductive belt clean for the next layer of toner to be transferred from the toner cartridges.

Paper picking

A sheet of paper (or transparency ﬁlm) is picked when a pair of cam-shaped rollers, driven by the paper-feed motor, rotate and force a sheet of paper from the stack into a pair of intermediate rollers. The intermediate rollers advance the sheet of paper to the aligning rollers. The paper is pushed against the aligning rollers slightly without them rotating to create a slight buckle in the paper, which aligns the sheet of paper parallel to the paper path. At this point, the paper remains stationary until the image is ready to be printed on the paper. The pick sensor detects whether the sheet of paper arrived at the aligning rollers.

Toner transfer to paper

Once all four layers of toner have been picked up on the accumulator belt, a sheet of paper (which has already been picked) is advanced to the second bias transfer roller. (In the user manual the second bias transfer roller is referred to as

the transfer roller , a customer-replaceable consumable.) The movement of the

sheet of paper is timed so that the leading edge of the toner image on the accumulator belt meets with the paper after 5 mm of the leading edge of the paper has passed. A strong positive voltage (+900 volts for plain paper, +1500 volts for transparency ﬁlm for 300 dpi printing and +1000 for 600 dpi printing on paper) in the second bias transfer roller, located under the sheet of paper, attracts the toner from the accumulator belt to the paper. The paper (or transparency ﬁlm) advances at the same speed as the accumulator belt.

As the toner is being transferred to the paper, the accumulator belt cleaning blade is activated. This blade scrapes any remaining traces of toner from the accumulator belt prior to the next image transfer of toner.

Theory of Operation

The strong positive potential of the second bias transfer roller attracts toner to the paper.

Theory of Operation

Fusing and exiting

As the paper receives the toner it passes through the fuser. A heated roller on the top surface of the paper melts the toner on the paper. Sandwiched between a pressure roller underneath and the heated roller on top, the melted toner bonds into the paper. An oil supply keeps the heated roller lubricated so that the melted toner does not adhere to the roller. Following fusing, the paper advances to the output tray. When not printing, the heated roller is held at a temperature of 160 printing, and 150

Depending on printer driver instructions, the paper may go directly to the output tray, printed side up. Or, if instructed, the sheet of paper may be routed to the reverser, which drives the sheet up a narrow channel and then reverses direction, and routes the sheet of paper to the output tray upside down. This is appropriate for a collated series of prints that need to remain in ﬁrst-to-last order.

Print modes

Theory of Operation

There are three print modes: Fast, Standard and Enhanced. Standard mode is 600 dpi, bi-level printing. Enhanced mode is 600 dpi, continuous-tone printing. Fast mode is 300 dpi, continuous-tone printing.

If no motion were involved, the laser dot produced would be an ovoid shape, measuring about 60 microns wide by 80 microns tall. In practice, to print a dot, the sweeping laser beam is left on long enough to create a roughly circular dot. In Standard 300 dpi printing mode, the area allowed for a pixel is 84 microns square. Toner particles attracted to the laser dot measure about 8 microns in size. Allowing for vertical stacking, a solid, 300 dpi pixel may consist of only 200 to 300 toner particles. For grayscale printing, even fewer particles would be deposited onto a pixel. As illustrated below, for printing 300 dpi solid dots the laser beam is pulsed at a 70% duty cycle at an amplitude of 0.7 mW. (A 70% duty cycle is used to create horizontal lines of equal thickness and scalloped appearance as vertical lines.) To achieve grayscaling of black and color, the beam’s duty cycle is sequentially stepped down to 0% to achieve 16 grayscale levels at 300 dpi.

Standard mode 600 dpi printing is achieved by cutting in half the speed of the photoconductive and accumulator belts and the paper transport. In addition, the laser energy is lowered to 0.5 mW and the laser pulse rate is doubled; this results in a slightly smaller dot.

For Enhanced mode, the laser beam duty cycle varies from 70 to 0% to create four grayscale color levels. A technique called 2-dot modulation, where one pair of laser pulses are combined, is used to create larger 600 dpi dots. Text and solid colors are written at a 600 vertical lines per inch rate, while grayscaled information is written at 300 vertical lines per inch.

Theory of Operation

Automatic color correction

The printer features a unique ability to measure how much toner it is depositing on the accumulator belt for a speciﬁc density of color. During this self-calibration sequence, the printer exposes a portion of the photoconductive belt with predetermined, stepped values of energy to produce a saturation dither pattern for each color. In each case, a certain, expected amount of toner should be transferred to the accumulator belt for each step. Reﬂective sensors, located adjacent the accumulator belt, optically sense how much toner was actually transferred to the accumulator belt; this is called the printer’s densimetric response. This response data is transmitted to the image processor board, which makes calculations and then downloads a color correction table to the print engine control board. The color correction table indicates the exact laser beam pulse duty cycle to produce properly saturated grayscales.

Image processor

Image rendering technology

The image processor board handles PostScript data sent from a host computer and transforms it into a format suitable for the print engine. The hardware/software structure that performs this function is called a graphics pipeline. The graphics pipeline is composed of ﬁve basic parts.

■ The I/O serializer handles the communication and protocol with the

parallel and SCSI port as well as communication with the installed network card. The particular installed network card handles Ethernet, LocalTalk or serial communication protocols.

■ The PostScript data received through the I/O serializer is routed to the

PostScript interpreter. The PostScript interpreter generates display lists which describe objects and text fonts as they are to appear on the printed page. As needed, the PostScript interpreter reads font data stored in ROMs on the image processor board. The PostScript interpreter also handles errors it encounters in the PostScript data.

■ The PostScript interpreter's display list is, in turn, routed to the

rasterizer. The rasterizer converts the objects and fonts into a bitmapped image composed of color planes. Color planes are bitmaps of the primary colors cyan, magenta and yellow that make up the image.

■ The engine driver outputs the color bitmaps to the print engine. It

handles the data transfer buffering and basic input/output functions.

■ The control loop, which oversees the operation of the graphics pipeline,

routes the color planes to the engine driver that transmits the color plane data to the print engine. The control loop also monitors the control and error signals fed back from the print engine.
