The Phaser 550 Color Printer
The Phaser 550 Color Printer combines a color laser, continuous-tone print engine with an image processor supporting Adobe’s PostScript Level 2 page description language. 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 printer supports Token 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 PCL printer language is optionally supported and is activated with a downloadable authorization code.
The Phaser 550 comes standard with 8 Mbytes of RAM which can be supplemented with one or two additional 16- or 32-Mbyte RAM SIMMs; maximum capacity is 72 Mbytes. The printer contains 17 standard, built-in fonts. An additional 22 fonts can be added via an optional snap-in SIMM (which also enables other extended features). The standard Phaser 550 prints at a resolution of 600 x 600 dots-per-inch.
The addition of the extended feature (font) SIMM allows the printer to print at higher resolutions of 600 x 600 (Standard mode), 1200 x 600 (Enhanced mode) and 1200 x 1200 (Premium mode) dots per inch. The extended feature Phaser 550 also supports image pipelining for greater throughput, a print collation mode, and a “check print before proceeding with job” mode.
The Phaser 550 support a 5 page-per-minute, composite-black printing called Fast Color. It also feature Presentation mode printing in which a paper print is printed with the color settings of a transparency print. Presentation mode produces the smoothest and brightest large-area fills. This mode can only be selected from the front panel. The printer print in monochrome at 14 prints per minute.
The printer also feature 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 requires a minimum of 24 Mbytes of RAM to support the CopyStation.
The printers support 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 supports legal-size paper when fed manually or from a Legal-size paper tray. The printer requires at least 12 Mbytes of installed RAM to support Legal-size printing. The printer also supports manual feeding.
1-2
Phaser 550 Color 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.
Print speeds depend on the chosen resolution and selected media. For resolutions of 600 x 600 (standard) and 1200 x 600 (enhanced) dpi, in color, the printer prints at 3.5 pages per minute (ppm) on paper. Monochrome printing is at 14 ppm on paper. Transparency film printing is always 1.5 ppm. For 1200 x 1200 (premium) dpi color printing, the printer color prints at 1.75 ppm. Monochrome printing is at 7 ppm. Transparency film printing is 1.5 ppm. The printer prints 600 x 600 dpi, composite black (CMY) draft prints at a rate of 5 pages per minute.
RAM and printer capabilities
The printer features 8 Mbytes of base RAM and two SIMM connectors which accept both 16- or 32-Mbytes RAM SIMMs. With more memory the printer gains the capabilities of printing at higher resolutions, printing without having to use image compression (which trades off less installed RAM for longer image processing time) and dual frame buffers for printing one image while processing a second image (which gives greater printing throughput). With additional RAM memory the printer’s capabilities increase as detailed in the following table:

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

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.

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.

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:

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.

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 set up in Windows: Select your parallel (LPT) port
in the list.
For a serial port set up 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.

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.

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.
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:
1.
2.
3.
4.
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.

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. 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:
1.
Make a backup copy of the /etc/printcap file.
2.
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.
3.
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
4.
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:
1.
Load the utility Advanced Configuration Tool (ACT) onto the file server through a workstation.
2.
Log on to a file server as supervisor with supervisor privileges.
3.
Run ACT and select Quick Configuration.
4.
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.
5.
Select a file server for the printer to service.
6.
Select a queue for the printer to service or create a new queue.
7.
Save the configuration.
8.
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.
2-34
9.
After all file servers have been configured, save the configuration file and restart the print server.
Phaser 550 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
1.
Add the printer name to the host table (/etc/host) and assign an IP address to the printer’s name.
2.
Assign a print queue to the printer by editing the /etc/printcap file.
Installing the Printer and Drivers

Configuring the printer
1.
Set the printer’s IP address as described in the earlier topic Setting the printer’s IP address using the front panel” on page 2-30. 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).
1.
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 by downloading the authorization code to the printer. Alternately, you can access and authorize the printer through a Web browser.
2.
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 550, in turn, finds all file servers with Phaser 550 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 2-34, 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.

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
1.
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
2.
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.
3
3.
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.

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.
1.
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
2.
From the host, issue the SHOW QUEUE /full command to list all the available printer queues. Ensure that the Phaser 550’s queue is listed.
3.
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

(16 to 24 lbs.)
Follow these guidelines when you make transparencies:
Use only Tektronix transparencies .
Be sure to load transparencies with the printing side down.
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.

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.

The imaging unit
The imaging unit forms the heart of the printer. This customer-replaceable unit contains the photoconductive belt and accumulator belt on which imaging takes place.
The laser scanner
The laser scanner is the device that “writes” the image onto the imaging unit’s photoconductive belt.
Phaser 550 Color Printer
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.

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.

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 600 dpi printing or 48 mm-per-second for 1200 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 1200dpi printing) to -550 volts (for 600 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
µ
400 varying charge of the belt surface, results in a uniform negative potential on the belt surface of -500 volts or -550 volts, depending on the selected dot-per-inch printing.

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 0.3 mW to 0.5 mW depending on whether the printer is printing in 1200 dots per inch (dpi) mode or 600 dpi mode. Following laser exposure, the negative potential of the belt varies from -500 volts or -550 volts (unexposed) to -10 or -20 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 23,000 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 exposed portions of the belt is about -20 volts, the greatest amount of toner is transferred. The developer roller rotates at 1.6 (600 dpi printing) or 2.13 (1200 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.
