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.

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.

Phaser 440 Color Printer
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.

A health LED indicates the status of the printer.
Blinking (at a steady rate): The printer is operating normally. The LED
■
blinks irregularly during diagnostics.
If a soft error occurs, the image processor board will operate, 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.
TEST button
The TEST button, located at the bottom right rear corner of the printer, has two
functions:
■
Following normal power-up, pressing the TEST button for 2 to
3 seconds prints a composite test pattern. Refer to Figure B-1 in
Appendix B,

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.

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
1.
Turn off the printer. LocalTalk protocol requires that you attach the
LocalTalk cable with the printer powered off.
2.
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.
3.
Turn on the printer and the computer.
Ethernet connection to a Macintosh
Note
1.
2.
3.
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

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.

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.

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.

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.

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:
1.

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 (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.
5.
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.
6.
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.
7.
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

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.
Use a text editor or word processor to modify the DEVPARAMS.PS
file. (Be sure to save the file as a text-only file.) Substitute the values
you want for the values used in the sample DEVPARAM.PS file. The
possible values for each parameter are listed in the following table.
The values are case-sensitive; they must be entered exactly as shown.

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:
1.
Make a backup copy of the /etc/printcap file.
2.
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 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, 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
2
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. If the printer is not displayed, refer to the Novell
NetWare configuration topic in the Network Utilities for Phaser Color Printers User Manual.
5.
Select a file server to be configured.
6.
Select a queue to service the printer or create a new queue.
7.
Save the configuration file.
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.
9.
After all file servers have been configured, save the configuration file
and restart the print server.
Service Manual

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
1.
Add the printer name to the host table (/etc/host) and assign an
Internet Protocol (IP) address to the printer’s name.
2.
Assign a print queue to the printer by editing the /etc/printcap file.
Configuring the printer
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’s site. This is done locally through the
serial or parallel port.
2.
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 (Reverse Address Resolution
Protocol) or BOOTP (Boot Parameter Protocol) configuration file to
automatically configure the printer’s IP address (although it will not
be stored in the printer’s NVRAM).
3.
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, a system’s log collect printer information for the network
administrator.
■SNMP (Simple Network Management Protocol), allows the system

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.

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.

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.
5
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.

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.
Lower Tray Assembly. Picking paper in a manner identical to the printer's
paper-feed unit, the Lower Tray Assembly's front door routes the sheet of paper
to the feed roller in the paper-feed unit.

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.

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.)

Phaser 440 Color Printer
Theory of Operation
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

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

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.

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

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.)

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.

#1 POSIDRIV®
■
Volt-ohm-meter (VOM)
Verifying the power supply involves four steps:
■
Measuring the input and output voltages
Inspecting the power supply fuses
■
■
Checking its +24 VDC safety interlocks
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.

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.”
