Service Guide

The Phaser 740 Color Printer
The Phaser 740 Color Printer combines a color laser, continuous-tone print engine
with an image processor supporting Adobe’s PostScript Level 3 page description
language. The image processor features a bi-directional parallel interface and a
10baseT Ethernet port for host communication. Optional network adapter cards to
the image processor allow the printer to communicate on networks using LocalTalk,
Ethernet 100baseT or Token Ring protocols. The Ethernet network card supports
EtherTalk 100baseT, Novell and TCP/IP. With the Token Ring network card, the
printer supports Token Ring protocols. With 32 Mbytes of RAM installed, the printer
supports the color PCL5C printer language too.
The printer is available in four configurations:
■
The
Phaser 740L
customer-upgraded to be a color printer. It prints at a resolution of 600 x
600. It is equipped with 16 Mbytes of RAM which can be supplemented
with an additional RAM DIMM. The printer contains 136 standard, built-in
fonts. The Phaser 740L is identical to the Phaser 740 except is set to only use
a black toner cartridge. It features a removable plate which blocks out the
locations of the color cartridges.
■
The
Phaser 740 Base
supplemented with one or two additional 16-, 32-, 64- and 128-Mbyte RAM
DIMMs; maximum usable capacity is 80 Mbytes. The printer contains 136
standard, built-in fonts. The printer contains 136 standard, built-in fonts.
The Phaser 740 Base prints at a resolution of 600 x 600 dots-per-inch.
is a monochrome version of the printer which can easily be
comes standard with 32 Mbytes of RAM which can be
■
The
Phaser 740 Plus
includes 32 Mbytes of additional memory (64 Mbytes
total) and a SCSI interface board. The presence of the SCSI board (and the
extra memory) enables the printer to print at higher resolutions 1200 x 1200
(Premium mode) dots-per-inch and also support image pipelining for
greater throughput, a print collation mode, and a “check print before
proceeding with job” mode. The printer contains 136 standard, built-in
fonts.
■
The
Phaser 740 Extended
(a factory-only option) features a different ROM
SIMM than the other printers. It includes 128 Mbytes total memory, SCSI
port, 1200 x 1200 color printing, check print mode, print job collation
(requires hard drive), copystation support and print pipelining.
The color printers support a 5.3 page-per-minute, composite-black printing “Fast
Color” mode which prints at 600 x 600 dpi using three passes, cyan, magenta and
yellow, to produce an image instead of the usual four passes, cyan, magenta, yellow
and black. Each printer also features “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. The printer prints in
monochrome at 16 prints-per-minute.
2
Phaser 740 Color Printer
Print speeds depend on the chosen resolution and selected media. For resolutions of
600 x 600 (standard), in color, the printer prints at 4 pages per minute (ppm) on paper.
Monochrome printing (Fast Monochrome) is at 16 ppm on paper. Transparency film
printing is always 2 ppm. For 1200 x 1200 (premium) dpi color printing, the printer
color prints at 2 ppm. Monochrome printing is at 8 ppm. The printer prints 600 x 600
dpi, composite black (CMY) draft prints at a rate of 5.3 pages-per-minute.
The plus and extended features option includes a SCSI-compatible interface to connect
to an external hard disk drive for additional font storage. The hard disk drive is also
required for print collation of multiple copy multi-page prints. A copy unit can also
be connected to the printer’s SCSI port to give the printer the ability to optically copy
color images. An factory-only, internal IDE hard drive can be installed in the printer
in place of the network card.
The printers support printing on A-, A4- and Legal-sized paper and transparency film
from separate A or A4- or Legal-size trays. An optional two-tray second feeder (called
the Lower Tray Assembly) is available. The printer features a built-in multi-purpose
tray from which specialty media, cardstock and envelopes can be fed. The printer also
supports manual feeding using the multi-purpose tray.
An optional auto-duplex unit allows the printer to automatically create double-side
prints. The duplex unit takes the place of the main (top) tray. The duplex unit
requires using the optional two-tray second feeder as a paper source. The duplex unit
upgrade kit includes the optional two-tray feeder. When printing double-sided, print
times are generally doubled. Double-sided monochrome printing is at 4 ppm, doubleside color at 2 ppm.
After being idle for the selected amount of time 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.
Service Guide

RAM and printer capabilities
The printer features two DIMM connectors which accept both 16-, 32-, 64-, and 128Mbytes RAM DIMMs. The printer can use off-the-shelf RAM meeting these
specifications:
■
168-pin DIMM
■
Synchronous DRAM
■
3.3 volt
■
9 nsec speed
■
Valid on-board Serial Presence Detect ROM.
The Configuration Page lists the amount of installed RAM and the details; such as
type, parity, size, and manufacturer, about the DIMM installed in each slot.
Upon power-up, the image processor interrogates the 256 byte Serial Presence Detect
ROM which describes the DIMM with details such as data width, clock delay, number
of address columns and row, refresh rate and more. If the DIMM does not meets the
required specifications it will be ignored; no error message will be reported.
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:

Button 1, the left-most button labeled the Exit key, cancels an operation while

the LCD labels the current function of each button.
In addition, pressing the buttons as you turn on the printer enables certain diagnostic
modes:
■
Pressing and holding Button 1, as you turn on the printer, skips power-up
diagnostics (except for a brief kernel test) and proceeds to PostScript
startup.
■
Pressing and holding Button 3, as you turn on the printer, executes
interactive service tests. Refer to “Service tests” on page 57.

The Phaser 740 rear panel
Test print button
In the center of the rear cabinet panel is the test print button. Pressing this button
while the printer is idle causes the print engine to print a built-in test print. The print
consists of a field of thin horizontal lines. The print is made independently of the
image processor board. Hold in the test button for at least 4 seconds before releasing,
or until you hear the print process begin. The print demonstrates that the print engine
can print (independently of the image processor); it has no use for determining print
quality.
Note
The Test Print button will not make a test print if the auto-duplex unit
is installed since the Test Print function defaults to the upper tray.

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 a small hole in the
rear panel. 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 at a reduced
capacity. Soft failures include failure of expansion memory DIMMs or any
of the interface ports. When a soft error occurs, the printer automatically
prints a startup page listing the error.
■ On 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 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 six tray types:
■ Letter (A-size) paper
■ Letter (A-size) transparency film
■ Metric Letter (A4-size) paper
■ Metric Letter (A4-size) transparency film
■ Legal-size paper
■ Auto-duplex unit
