General Information

Phaser 440 overview

The Phaser 440 Color Printer is an Adobe PostScript Level 2 (version 1.3) color, dye sublimation printer with Tektronix color matching extensions (TekColor 3.0). Printing at an addressability of 300 dots-per-inch, the printer features a single paper tray (Universal size) that holds A, A4, and Letter Extra media with an optional Lower Tray Assembly (A or A4 only) which gives the printer a dual-tray capability. (The Lower Tray Assembly is sometimes referred to as the second feeder.) The printer prints images on A- and A4-size paper and transparency ﬁlm with 5 mm (0.2 in.) margins as well as Letter Extra paper which allows for full-size A and A4-size bleeds. The Phaser 440’s image processor is powered by a 24-MHz RISC processor and features integral EtherTalk. The EtherTalk port supports 10Base5, 10Base2 and 10BaseT external line units. Also standard are 16 Mbytes of RAM (expandable to 64 Mbytes), 39 standard fonts, and support for an external SCSI disk for additional font storage. For host image input, the image processor also features a standard parallel port, an RS-232 serial port and a LocalTalk port. The Phaser 440 optionally includes support for Novell NetWare and TCP/IP networks (with the Ethernet card installed).

Dye sublimation printing

Dye sublimation printing is an extension of thermal wax transfer printing. Many of Tektronix’ current and older printers are based on thermal-wax transfer technology. During the dye sublimation printing process, transfer roll dye, in contact with a sheet of special paper, is vaporized (sublimed) into the surface of the paper by an electronically controlled thermal head. The thermal head features individually controllable heating elements at 300 elements per inch that span the width of the printing paper and the transfer roll. The temperature of each element can be controlled so that a speciﬁc amount of dye is vaporized into the paper. This allows the printer to produce a remarkably wide range of colors and shades with detailed precision.

The printer, using the subtractive color method, transfers sequential layers of yellow, magenta, cyan and black dye into the paper to create its full gamut of color.

The printing paper is an ultra-smooth coated paper. Since the transferred dye penetrates and bonds into the surface of the paper, the prints are durable and do not scratch, rub off, or retransfer to other materials.

General Information

Combination sensors and their meanings

Combinations of sensors are used by the Phaser 440 print engine to determine the type of transfer roll and the type of media tray installed in the printer.

Transfer roll type sensing

The combinations of the three transfer roll core sensors “tell” the print engine what type of transfer roll is installed. The length of the cores (long or short) actuate the switches. Long cores close the switches, turning them on.

Media tray type sensing

The combinations of the three tray sensors “tell” the Phaser 440 print engine what type of paper tray is installed. (The print engine does not detect the type of media installed in the tray; it only detects the particular tray being used.) The tray sensors are located on the right-side interior of the paper tray slot. There are three tray types:

■

Letter (A-size). This tray is sized for 8.5 x 11-inch paper and

transparency ﬁlm. A slide switch on the side of the media tray lets you select either paper or transparency ﬁlm.

Metric Letter (A4-size). This tray is used for 210 x 297 mm paper and

■

transparency ﬁlm. A slide switch on the side of the media tray lets you select either paper or transparency ﬁlm.

■

Universal. This tray is used for A, A4, and Letter Extra paper and A

and A4 transparency ﬁlm. The extra-long and wide Letter Extra paper allows users to print full-page bleeds. After cutting the print down to either 8.5 x 11 inches or 210 x 297 mm, the result is an A- or A4-size print in which the image bleeds off all four of the paper’s edges with no unprinted margins. A slide switch on the side of the media tray lets you select either A, A4 or Letter Extra as well as paper or transparency ﬁlm. The Universal tray can only be used in the printer’s main tray feeder; the Lower Tray Assembly accepts only the Letter (A-size) and Metric Letter (A4-size) trays.

Front panel LED service mode error codes

Detected error conditions in the print engine are displayed on the front panel as LED patterns. The following table lists the service mode error codes which are displayed while the printer is in service mode. (Service mode is explained in Chapter 9, “Checks and Adjustments.”) These codes are more speciﬁc than the error codes displayed during normal operation (see the previous topic “Rear panel”). If an error occurs during normal operation, pressing the rear panel TEST button causes the more speciﬁc service mode error code to be displayed on the front panel. The error codes listed below are explained in greater detail in the Chapter 6 topic “Print engine error codes and their causes” on page 6-19.

Installing the Printer and Drivers

This chapter discusses installing the printer and its drivers as a part of the S0 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 Its Hosts” explains how to verify that the printer, the host driver and the connection between them function correctly.

■

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

Cabling the printer

Installing the Printer and Drivers

Note

This topic explains making a hardware connection between a Phaser 440 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 would be through the printer's LocalTalk port. A networked connection for a Macintosh will most likely be either a LocalTalk network or an Ethernet network.

LocalTalk connection to a Macintosh

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

For a direct connection, attach the interface cable or adapter to the host computer's LocalTalk port. (The port has a printer icon printed next to it.) Attach the other end to the printer’s LocalTalk port.

For a LocalTalk network connection, attach the network adapter to the printer's LocalTalk port.

Turn on the printer and the computer.

Ethernet connection to a Macintosh

Note

For an Ethernet connection, the printer must have the Ethernet option card installed. An Ethernet “Installed” label will be attached to the rear panel next to the Ethernet connector.

Turn off the printer. Ethernet protocol requires that you attach the Ethernet cable with the printer powered off.

Attach the Ethernet network adapter to the printer's Ethernet connector.

Turn on the printer. During the printer's boot-up process, the printer's network name or node address is resolved with the network and is displayed in the Mac's Chooser.

Installing the Printer and Drivers

Turning on the printer

The startup page

When you turn on a Phaser 440 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 been enabled. After running self-tests and printing the startup page, the printer is ready for operation. The factory default condition is to have the startup page disabled. A downloadable PostScript utility ﬁle, found on the Drivers and Utilities diskette, allows you to enable or disable the startup page.

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

■ Fonts

■ Ports (Serial, Parallel, LocalTalk, Ethernet)

■ Printer name

■ Ethernet protocols

■ TekColor corrections and print quality mode

■ Pages printed

■ RAM installed

■ Tektronix version ﬁrmware

■ Adobe PostScript version software

■ Ethernet address

■ TCP/IP authorization code

■ Type of transfer roll loaded

■ SCSI disk attached

If the printer detects a non-fatal error at power-up, the startup page prints with an error message shown in red. This is true, even if the startup page has been disabled; the printer will still force a print to report the error.

The conﬁguration page

To provide further diagnostic information, the printer is able to print a conﬁguration page. The conﬁguration page lists the values that the printer stores in its NVRAM. These values can be informative when troubleshooting the printer, particularly networked operations. A downloadable PostScript utility ﬁle, found on the Drivers and Utilities diskette, allows you to print the conﬁguration page. You can also use the rear panel DIP switches to print one. To print a conﬁguration page, while the printer is powered-up and idle, toggle rear panel Switch 4 up until printing starts and then down.

The conﬁguration page gives you the following information:

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

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

■ Color settings such as Photoﬁne enabled and Vivid Blue

Note

A Phaser 440 printer uses the Adobe PostScript Level 2 language. To take advantage of the Level 2 features, Tektronix developed the Tektronix Phaser driver which appears in the Chooser, along with the LaserWriter 7.0.x driver. The Phaser driver includes special paper sizes for each printer and TekColor color correction adjustment options. Refer to the Phaser 440 Drivers and Utilities

Printing Reference for more details.

Turn off any anti-virus software running on the Macintosh before installing the Tektronix software.

To install the Tektronix driver with system 6.0.7 or higher

Note

Macintosh computers on a network should have a minimum of system software 6.0.7 installed.

Place the Phaser Drivers and Utilities diskette (Macintosh) into the disk drive.

Double-click on the Installer icon and click OK at the introductory screen.

In the Easy Install window, click the Install button.

Click the Restart button in the dialog box that appears.

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

LaserWriter 7.0.x and its support ﬁle (PrintMonitor) are required to use the Tektronix driver and to print in the background. The Installer automatically copies these ﬁles to your hard disk drive if you are using system 6.0.7 or higher.

The printer driver diskette contains an EtherTalk Zone snippet you can use to reprogram the printer to reside in another EtherTalk zone, if necessary.

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 that 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.

■ For a parallel port setup in Windows: Select your parallel (LPT) port

in the list.

■ For a serial port setup in Windows: Select your serial (COM) port in

the list. Choose the Settings button to see the Settings dialog box. Fill in each item according to your conﬁguration, then choose the OK button. Refer to your Windows documentation for details, or ask your network administrator for help.

Other communications ports may include EPT: (an interface for the IBM Page-Printer, which requires the installation of a special card in your computer), and LPT1.OS2 and LPT2.OS2, which Windows may require if you are using certain spoolers or other add-on software programs. 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 Timeouts. 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 a value 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 Setup 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

Start Windows.

Open the Control Panel.

Double–click on the Printers icon.

Choose the Add>> button; a list of printers is displayed. Highlight the Tektronix printer you want to use.

Select Install Unlisted or Updated Printer.

Choose the Install button.

Note

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 diskette with the updated PSCRIPT.DRV ﬁle, enter system as the location so that 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 setup, 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.

Service Manual

2-23

Installing the Printer and Drivers

Note

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 (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, and drag the object onto the desktop and release the mouse button.

The Create a Printer dialogue 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 LPT2PRIN.

Scroll through the printer drivers listed to locate the proper Tektronix printer driver name. If it is listed, select it, otherwise, point the cursor to any other driver listed and click the right mouse button. Click Install from the menu options.

In the Install New Printer Driver dialogue box, 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.

At this point, 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 440. 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 dialogue box. Before leaving the Create a Printer dialogue box, adjust the printer port timeout setting.

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

10.

To create the new printer object on the desktop, click on Create. A new printer driver object is placed on your desktop. Conﬁrm and adjust the settings for this printer driver by launching an application program and performing the following steps.

Bring up the Settings Notebook by clicking the right mouse button on LPT2 PRINTER. Click on the arrow to the right of OPEN; click on SETTINGS.

Select the Printer Driver Tab. Conﬁrm that the Tektronix Phaser 440 is selected (highlighted). Double-click on the Phaser 440 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 Legal-size paper. This is the recommended setting. Next, select Device Defaults, set Form to Legal and set Orientation to Landscape. One of the most likely causes of printer errors is that the document and device defaults do not match.

Select Options and make sure that it is set to Phaser 440. If not, repeat the previous steps. While in this screen, set Job and Wait to 0, if they aren't already. Select the Output Tab. Ensure that the proper port is selected.

Select the Queue Options Tab. Activate a check for both Printer Speciﬁc Format and Job Dialog Before Print. Return to the Settings Notebook dialog box and close it.

If LPT2 PRINTER is not the only printer object on the desktop, then you may want to make it the default printer before opening a software application. To do so, point the cursor to the LPT2

PRINTER object, click the right mouse button, click on Set Default, and select LPT2 PRINTER.

Conﬁguring the printer's serial port for a PC

Use the PostScript command ﬁle DEVPARAM.PS (also located on the Utilities diskette) to modify the printer’s serial port settings.

To modify DEVPARAM.PS you should be familiar with the PostScript setdevparams command. This ﬁle lets you conﬁgure the printer's serial port. The following example sets ﬂow control to Xon/Xoff, parity to none, data bits to 8, stop bits to 2 and the baud rate to 9600. In the example below, the changes are persistent across print jobs and across power cycles; they remain in effect until speciﬁcally changed again.

Note

When you change the settings for the serial port, the baud rate DIP Switch 7 on the printer's back panel must be down before the changes will take effect.

CTRL-D is the ASCII End-Of-Text (EOT) character.

Using

printcap

to conﬁgure a Unix 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.

Add to the printcap ﬁle a new print queue name and set the port parameters as needed. Add 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, type:

chmod +x if

If communication to the serial port uses 7 data bits, the value for xs changes as follows. All other setup parameters remain the same.

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 to set up a print queue to support the printer on a Novell network. The Network Utilities for Phaser Color Printers User Manual gives the step by step procedure you follow to perform this conﬁguration. There are two methods, each using a different utility program, that you can use to conﬁgure the ﬁle server and set up print queues. In brief, this is what you will do:

Installing the Printer and Drivers

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. If the printer is not displayed, refer to the Novell NetWare conﬁguration topic in the Network Utilities for Phaser Color Printers User Manual.

Select a ﬁle server to be conﬁgured.

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

Save the conﬁguration ﬁle.

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.

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

Service Manual

2-29

Installing the Printer and Drivers

Alternatively, 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 printer name (TEKxxxxxx) as it is shown on the printer’s conﬁguration page. (Refer to the topic “Printing the conﬁguration page” on page 6-32 for details on printing the conﬁguration page.)

Conﬁguring TCP/IP

This is a brief overview of the steps you follow to conﬁgure the host and the printer for a TCP/IP network. The Network Utilities for Phaser Color Printers 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 Internet Protocol (IP) address to the printer’s name.

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

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’s site. This is done locally through the serial or 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.

Verifying the Printer and Host Connections

In this chapter, you verify that the host computer can send ﬁles to the printer. This chapter assumes that the printer and the printer drivers have been properly installed as explained in the previous chapter “Installing the Printer and Drivers.”

Verifying printing from a Macintosh

Selecting the printer via the Chooser

This procedure applies to both operating system version 6.0.7 (and higher) and system 7.0 (and higher).

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 station, maintains queues for the print ﬁles created and sent for printing from other workstations on the network. The printer, in turn, ﬁnds all ﬁle servers with Phaser 440 queues and extracts its print ﬁles from them. You must determine if a station can communicate a print ﬁle to the ﬁle server.

Generally, as outlined in the Chapter 2 topic “Conﬁguring a Novell NetWare server for the printer” on page 2-29, 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.

Type:

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

where <queue name> is the name established by the network administrator of a queue the printer is to service, such as TEK440. L=1 speciﬁes port LPT1

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

%! showpage

Then 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 that the printer is using is 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.

When 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.

Verifying and printing using the TCP/IP protocols

The Phaser 440 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 Phaser 440 conforms to Ethernet IEEE 802.3 network speciﬁcations.

UNIX

To verify the host-to-Phaser 440 (UNIX host) connection, execute the ping command from 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.

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, send a simple ﬁle such as the one of the snippets included in the software diskettes: conﬁg.ps causes the printer to print out its conﬁguration page.

If the page prints, then both the printer and the network connection are working correctly. If the print ﬁle cannot be sent, then a problem probably exists in the network set-ups for the printer. You and the network administrator should repeat the TCP/IP installation as outlined in the printer’s Network manual.

Print engine

Sublimation dye transfer — the engine's printing technology

To make colored prints, the print engine uses a color printing method called

sequential sublimation dye transfer printing . Simply said, the print engine prints by

subliming or vaporizing dots of colored dye from a Mylar® ribbon into a sheet of paper. The beneﬁts of this method are high-resolution, continuous tone printing, easy maintenance, and fast printing.

The print process

Figure 5-2 illustrates the printing process employed by the print engine. In the printing process, a single piece of coated paper (or transparency ﬁlm) is drawn past a thin Mylar ribbon, called a transfer roll, which is coated with sequential bands of colored dye: yellow, magenta and cyan and, in the case of 4-Color Transfer Rolls, black. A heating device, called a thermal head, vaporizes the colored wax from the transfer roll into the paper. The thermal head is an electrical device containing 2816 individually controlled heating elements aligned parallel to the short axis of the paper it prints upon. And because the row of thermal elements span the width of the page, the print engine prints an entire line at one time; this accounts for the print engine's fast print time. The printer uses a special paper which presents an ultra-smooth, ﬂat surface for the dye to absorb into.

During printing, the print engine moves the paper past the thermal head three times when a 3-color transfer roll is used (or four times for 4-color transfer rolls). During each pass of the paper, individual thermal head elements sublime tiny dots of dye from the transfer roll's colored bands; ﬁrst from the yellow band, then the magenta band, and ﬁnally, cyan. (For 4-Color Transfer Rolls, black is transferred last, after cyan.) The overlaid colors combine on the paper to produce a complete color image. After the three passes, the ﬁnished copy is ejected from the printer. The dye transfer roll is supplied on one spool, feeds past the thermal head and drum for printing, and collects on a take-up spool.

5-2

Phaser 440 Color Printer

Theory of Operation

Continuous-tone printing

The dye sublimation process can overlay precise amounts of dye onto each printer dot with much more precision than its cousin, the thermal-wax printer. Consequently, each dot is the exact color it should be, not an approximation. This results in what is called continuous-tone printing. Where thermal-wax printers must simulate a color by arranging a matrix of cyan, magenta, and yellow dots together in a speciﬁc pattern called a halftone to trick the eye into seeing an intermediate color, the dye sublimation printer can print that actual color with a single dot. Because the printer can create continuous-tone colors, the printer can output photorealistic prints.

Image data

Creating colors

A Phaser 440 print engine must receive data in a speciﬁc format to correctly print the image that the data represents. The printer's image processor board must convert the data into the correct format. The following topics describe some of the data formatting that the host or the interface module must perform.

The print engine prints an image in a raster format, line by horizontal line, dot by dot. The image to be printed is “described” with the colors yellow, magenta, cyan and black. First the yellow raster making up the image is printed, then the magenta raster is printed, and ﬁnally, the cyan raster. It is the responsibility of the image processor board to communicate the image data, serially, to the print engine, in this order.

As mentioned earlier, a Phaser 440 print engine prints only the colors cyan, magenta, yellow and black. However, these colors, called primary colors, can be mixed together to simulate other colors, called secondary colors. When tiny dots of two primary colors are intermixed, your eye perceives a third color. That is how the print engine can use just three basic colors to create multi-colored images. For example:

Cyan and yellow intermixed produce green.

■

Cyan and magenta intermixed produce blue.

Yellow and magenta intermixed produce red.

■

Mixing yellow, magenta and cyan produces the color black.

It is the responsibility of the image processor board to output, to the print engine, the CMY-encoded data in the proper sequence to produce the desired shade.

Theory of Operation

CPU

Phaser 440 print engine CPUs consist of a microprocessor, ROM, RAM and a clock circuit. The CPU is the heart of the print engine. It controls the timing controller, the mechanical controller, and print engine diagnostics.

Interface buffers

The interface buffers receive data from the image processor board, where the image data was received from the host computer and processed into data for the print engine. The interface buffer routes received data signals to the data controller.

Data controller and line buffers

The data controller receives input data from the interface and stores it in a data buffer. The data buffer contains two buffers: one buffer holds the current line of image data being transmitted to the print engine and the other buffer holds the preceding seven lines of image data received by the print engine. When the data buffers contain all eight lines of data, then the data controller transfers the data to the heat controller.

Heat controller (dot compensation)

Each thermal heating element must receive sufﬁcient energy to vaporize dye properly. Too much energy and the dye dot smears when printed. Too little energy, and the dye dot is ill-formed and does not adhere to the paper. In the heat controller, the data of the current raster line to be printed is compared with previously printed lines. The dot compensator determines when, and for how long, the individual thermal head elements should be energized to properly vaporize dye onto the paper. This comparison accounts for the thermal energy stored in each heating element from its previous dot printing action as well as the thermal energy picked up from adjacent heating elements.

In this comparison, the heat controller determines, for each dot to be printed, if the heating element was used to print any dots during the few lines, and also if any neighboring dots were or will be printed next to the dot in question. Knowing this history, the heat controller can determine how long to sustain the voltage pulse to the dot's heating element to correctly print the dot. This information is transferred to the line memory buffer.

5-6

Phaser 440 Color Printer

Theory of Operation

Thermal head controller

The thermal head controller uses the information received from the heat controller, in conjunction with timing signals, to drive the thermal head with the data stored in the line memory buffer. The head controller generates several different strobes. These strobes ranging from long pulses for “cold” thermal elements, to short pulses for “hot” elements. During printing, the strobe length is varied, based on the overall thermal head temperature and the volume of dots printed in a line. The voltage level of the pulse is switched between 13.5 VDC for transparency ﬁlm to 15 VDC for paper.

Thermal head

The thermal head is the device that vaporizes dye dots onto paper. It contains a row of 2816 solid-state heating elements. The actual number of elements used during a particular print depends on the paper size (A, A4 or Letter Extra) and the image to be printed. The thermal head prints raster lines parallel to the short axis of the paper.

During printing, the information in the line memory buffer is latched to the printhead elements and the elements are strobed to print a line. While the elements are active, the data in the line memory buffer determines how long each element is allowed to remain turned on. A line is printed in 7.7 msec (11.8 msec for transparency ﬁlm). The thermal head also contains a heating element that is activated, prior to printing, when the thermal head is cold. The heating element quickly warms the entire thermal head to the thermal head’s operating temperature and then turns off. Three fans keep the thermal head from overheating during printing.

Mechanical controller

The printer engine mechanical controller interfaces the CPU to the print engine’s motors, sensors, solenoids and fans. By interpreting signals from the sensors, buffered by the mechanical controller, the CPU keeps track of the paper drum position, transfer roll position and paper position during printing. Based on this information the CPU determines the proper time to transmit signals to the mechanical controller to advance the paper, energize a solenoid, or check a sensor.

Internal test pattern generator

This circuit produces the print engine's internal test patterns. The test pattern algorithms are stored in ROM. The internal test pattern data are routed to the interface block and pass through the rest of the print engine just as regular image data would.

Theory of Operation

Paper path in operation

This topic discusses the movement of a piece of paper from the paper tray, through the printing process, to the printer's output tray.

Paper pick-up

Paper pick-up takes place at the paper-feed unit. It begins when the pick-up solenoid energizes and the paper-feed motor rotates forward. This causes the pick-up roller (gear-driven by the paper-feed motor through a one-way clutch) to force a sheet of paper from the tray to the feed rollers. The pick-up solenoid allows the pick-up roller to rotate only long enough to force the paper into the feed rollers. The pick-up solenoid then de-energizes so that the pick-up rollers are disengaged from the gear train. The feed motor continues to rotate forward, causing the feed rollers (also gear-driven by the paper-feed motor) to carry the sheet of paper to the aligning rollers. As the paper passes through the paper-feed unit, it triggers paper-pass sensor 1 which checks to see if the paper made it to the aligning rollers.

Note that the action of the feed rollers forcing a sheet of paper into the aligning rollers aligns the sheet of paper to the paper path. There is a slight pause between the time the paper strikes the aligning rollers (resulting in a slight buckle in the paper, at which time the alignment takes place) and when the aligning roller solenoid is energized, which allows the aligning rollers to rotate and drive the paper to the paper clamp.

Also note that, although unrelated to the paper pick-up process, the drum rotates backward (counterclockwise) against a pair of stops that force the clamp open to receive and clamp the leading edge of the paper when it reaches the drum.

Drum loading

As the paper passes beyond the aligning rollers, it triggers paper-pass sensor 2. This activates the transfer roll feed motor long enough to apply tension to the transfer roll, pulling it taut. The aligning rollers carry the sheet of paper to the spring-loaded paper clamp, waiting in the clamp open position to capture the leading edge of the paper.

Theory of Operation

The drum slowly rotates forward (clockwise, viewed from the left side), automatically closing the spring-loaded clamp until the paper-clamp sensor 1 detects the paper loaded in the clamp, and then speeds up to draw more of the paper around the drum. Paper clamp sensor 2 double checks that the paper is still clamped in the drum as it rotates. The drum rotate for a complete revolution to clear the paper out of the paper load path. It continues rotating until the leading edge of the paper (the clamped end) is beneath the thermal head, ready for printing.

The position of the drum is determined by the drum motor. At this time, the transfer roll motor is energized to draw the transfer roll to its start position with the leading edge of its yellow band at the thermal head. The sheet of paper and the transfer roll are now in position for printing.

Theory of Operation

Printing

After checking the transfer roll's position (through the transfer roll mark sensors) the thermal head lift motor rotates an eccentric cam to push the thermal head down from its standby position to its print position, sandwiching the transfer roll and paper together between the thermal head and the drum.

Printing begins as the drum slowly rotates forward (clockwise) drawing the paper and the transfer roll past the thermal head where dye is vaporized from the transfer roll onto the paper to form a printed image. Contact friction between the moving paper and the transfer roll moves the transfer roll past the thermal head at the same rate as the paper.

The sheet of paper is drawn past the thermal head three times to form a complete image. When the ﬁrst pass (yellow printing) is completed, the thermal head lift motor raises the thermal head to its standby position allowing the paper clamp to pass underneath. When the paper reaches the print-start position, the thermal head lift motor rotates to bring the thermal head back to the print position, and printing continues with magenta printing. This process repeats again for cyan printing and black and then the print is ready to be unloaded to the printer's output tray. (During forward rotation, the drum stops are simply pushed out of the way. The drum stops can only open the clamp during reverse drum rotation.)

The Phaser 440 does not reverse the drum to “back up” the print to the start position for each pass during printing. This is one of the reasons for the Phaser 440's fast print times.

Print unloading

To unload the print after printing, the drum rotates clockwise until the trailing edge of the paper ﬂips out into the exit path, then the drum motor rotates the drum counterclockwise to the clamp-open position. This also pushes the print to the lower exit rollers. The paper-feed motor, running backward for a set amount of time, drives the lower and upper exit rollers, which pull the print through the rollers and out to the printer's output tray. The print engine checks to make sure that the paper's trailing edge has passed the paper-exit sensor. After a set amount of time, the drum rotates to park the paper clamp under the bail rollers (to prevent them from denting the drum). Then the paper-feed motor is turned off, completing the print process.

Theory of Operation

Fusing is provided by two in-line fuses on the AC input line. Overvoltage protection for the VH, +24 VDC and +5 VDC supplied is provided by a “crowbar” circuit formed by a Zener diode and an SCR. VH overcurrent is sensed and regulated by altering the oscillations of the pulse-width-modulator that generates the voltage. Overheating is detected by a thermostat that also shuts down the pulse-width-modulator oscillator.

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

pipeline

■

. The graphics pipeline is composed of ﬁve basic parts.

The I/O serializer handles the communication and protocol with the host computers connected to the serial, parallel, Ethernet, and LocalTalk ports as well as the SCSI port. A special portion of the I/O serializer is dedicated to handling the multi-layered AppleTalk protocol.

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

Chapter

Troubleshooting

This chapter discusses troubleshooting a Phaser 440 printer. Troubleshooting is discussed with two approaches:

■

A step-by-step veriﬁcation procedure that systematically conﬁrms that particular components of a printer are properly functioning until a problem is found.

■

A symptom/cause scheme that lists particular printer failures and error codes and their possible causes.

System power-up sequence

The following lists the chain of events that occur when you turn on a printer. You can follow this list as one means of determining if the printer is operating correctly.

Power switch turned on:

The front panel LEDs are momentarily lighted and then turned off. The POWER LED remains on all the time since it is wired to +5 VDC. The READY LED ﬂashes during the printer initialization.

The thermal head lift motor energizes to raise the thermal head into its standby position if it is out of position. The position is sensed by the thermal head position sensors.

The transfer roll feed motor energizes and advances the transfer roll one set of color panels until a yellow band is detected by the transfer roll mark sensors. This also occurs each time the transfer roll is removed and reinstalled in the printer.

The drum motor rotates the drum about one and one-half revolutions.

The drum is reversed for half a revolution. At the same time, the paper-feed motor runs for about 3 seconds. This action ejects any sheet of paper that may have remained in the printer following an abnormal power-down.

Service Manual

6-1

Troubleshooting

Following the drum reversal, the drum motor rotates the drum forward for a quarter of a revolution to position the paper clamp under the bail rollers. This prevents the bail rollers from forming depressions in the drum.

The READY LED then blinks while the image processor initializes. Following initialization, the READY LED is on.

The print engine is initialized. The engine fan runs continuously while the printer is on. The large thermal head fans runs during printing and while the thermal head temperature is greater than 35 head fans run during printing or when the ambient temperature inside the printer exceeds 40

This topic is a step-by-step procedure for systematically verifying particular aspects of a printer's operation. Following this procedure should lead to the cause of a printer's failure.

Verifying image processor operation by using the Test Pattern Generator

Instructions for using the Test Pattern Generator are provided in Appendix D “Test Pattern Generator.”

Attach the Test Pattern Generator to the printer's parallel port. The Test Pattern Generator can be attached to the printer while the printer is turned on.

If the printer does not power up go to the later topic “Verifying power supply operation” on page 6-3.

Observe that the READY light is on (not blinking). If it does not light, go to the later topic “Verifying power supply operation” on page 6-3.

Select any test pattern using the Test Pattern Generator's four DIP switches and then press its print button.

After the print is made, remove the Test Pattern Generator.

If the printer prints a test pattern, then the printer's image processor board and print engine are working correctly. The printer's problem resides with the host computer-to-printer connection, or the host computer. Refer to the appropriate topics in Chapter 3 “Verifying the printer and its hosts.” (Note that since the Test Pattern Generator prints only through the parallel port, the possibility also exists that the hardware of any of the other hosts interface ports could be non-functioning, and could be the source of the print failure. In this case, the printer should be able to print from another port, except the non-functioning port.)

6-2

Phaser 440 Color Printer

If the printer does not print a test pattern, then a problem exists with the printer's image processor board or the print engine. Proceed with the topic “Verifying print engine operation by using its self-test print” on the next page.

Verifying print engine operation by using its self-test print

If not already on, turn on the printer. If the printer does not power up, go to the topic “Verifying power supply operation” below.

Once the READY light is on (not blinking), press and hold the TEST button for 5 seconds. The printer should print out a test pattern.

If the printer prints a test pattern, then the print engine is working correctly and the printer's problem resides with its image processor board. Refer to the later topic “Image processor self-diagnostics” on page 6-31.

If the printer does not print a test pattern, then a problem exists with the print engine. Proceed with the topic “Verifying power supply operation” below.

Testing for a shorted motor which would shut down the power supply

■

Measuring power supply voltages

Turn off the printer and unplug it from its power outlet.

AC Input: With the VOM set to measure AC voltages, measure for

power being supplied to the printer. It should measure between 87 to 128 VAC (115 VAC nominal) or 174 to 250 VAC (220 VAC nominal). Ensure that the switch is correctly set.

Troubleshooting

DC Output: With the VOM set to measure DC voltages, measure for

+5 VDC and +24 VDC. The following illustration shows the test points. Be aware that the +24 VDC supplied to the motors is supplied directly through the cover-open safety interlock switches. Refer to Appendix C, “Wiring Diagrams” for more details on other voltage test points.

Thermal head voltage: With the VOM set to measure DC voltages,

measure for the thermal head’s VH voltage at its power harness. Refer to the topic “Power supply thermal head voltage (VH) check” on page 9-5.

Engine fan : Ensure that the power supply fan runs while the printer

is turned on. The fan blows into the card cage (toward the image processor board).

If you do not measure DC voltages, proceed to the next step “Inspecting the power supply fuses.”

If the +5 VDC and +24 VDC voltages measure correctly, but the printer does not operate correctly, then proceed to the procedure “+24 VDC safety interlocks.”
