General Information
This service manual contains information useful to verify operation,
troubleshoot, repair, adjust, and maintain a Tektronix Phaser® 600 Color Printer.
The first half of this manual familiarizes you with the printer; it provides
information on installing and verifying the printer and training printer
customers as a part of the Option S0 printer installation procedure. The latter
half of the manual includes troubleshooting guides, adjustment procedures,
assembly/disassembly procedures and an FRU list.
To ensure complete understanding of the product, we recommend participation
in Phaser 600 Color Printer service training, if available.

General Information
Printer overview
The Phaser 600 Color Printer is a wide-format, Adobe PostScript Level 2 color,
solid ink-jet printer. It features PostScript version 2015.105 with Tektronix color
matching extensions (TekColor 4.0 and VPI), HPGL-C and includes a TrueType
renderer for downloaded TrueType fonts.
The Phaser 600 Color Printer prints at an addressability of 300 dots per inch
(dpi) and features 17 built-in fonts and 8 Mbytes of RAM, which can be
upgraded to either 24 Mbytes or 40 Mbytes with the addition of one 16-Mbyte or
one 32-Mbyte RAM SIMM. The printer also features a 1-Gbyte internal hard
drive to spool large image files for wide-format prints. With the addition of the
Extended Features SIMM (either the Roman or the Kanji SIMM) the printer then
features 39 (Roman) or 59 (Kanji) built-in fonts, Copystation support, Reprint
support, and Print Preview.
The printer prints from roll-fed media. An automatic cutter cuts the roll-fed
print from the roll when the print is complete. Sheet media can also be manually
fed into the printer. Supported cut-sheet media sizes are Metric: A3 through A0;
US: B through E; and Architectural, 24 x 36 in., 30 x 42 in., and 36 x 48 in.
Roll-fed media range in width from 420 to 914 mm (16.5 to 36 in.) with a
maximum roll diameter of 127 mm (5 in.).
Unique to the Phaser 600 Color Printer’s solid-ink technology, the printer can
print on a wide variety of media types, including standard paper, heavy paper,
Vinyl (such as Scotchcal), Artist’s canvas, and backlit display acetate. The
printer can handle media ranging in thickness from 0.1 to 0.5 mm (0.004 to
0.020 in.) thick.
The printer is powered by a 50-MHz 29K RISC processor. The printer features
integral bi-directional parallel and SCSI ports. A rear panel slot allows
customers to install one “smart card” PhaserShare Network Card. One card
provides an RS-232C serial port and a LocalTalk port. A second, alternative card
offers an Ethernet port which includes standard support for EtherTalk, Novell
NetWare and TCP/IP protocols. A third card provides a Token Ring interface
supporting Novel NetWare, TokenTalk, and TCP/IP.

Solid inks
Solid inks, sometimes called phase-change inks, are solid at room temperature
and are liquid at the higher temperature used during printing. The inks solidify
almost instantly after being jetted onto the printer’s media. Because Tektronix'
proprietary solid inks bleed much less than ordinary liquid inks, they allow the
printer to print brilliant colors on plain paper.
Note
Turning the printer off and allowing it to cool causes it to perform a
printhead cleaning and purge cycle upon power-up. The printer's
purge cycle consumes some ink. During normal use and servicing,
turn the printer off and allow it to cool only when necessary.
Memory considerations
The capabilities of the printer increase with the addition of more RAM.

General Information
The printer features a printhead maintenance system used to clean the printhead
faceplate and clear clogs from the printhead nozzles. The system consists of a
the maintenance station assembly, a vacuum pump, a filter, air tubing, and a cam
gear (for positioning the maintenance station).
Sensors in the printer provide information to the engine control board to
determine the state of the printer. The printer monitors the positions of some of
the movable assemblies, such as the printhead, as well as the temperature of the
printhead and fuser bar.

The image processor board
Prominent on the image processor board is the ROM code SIMM and the RAM
SIMM plug-in modules. Network connection is provided through the plug-in
network card. The printer stores unique printer status and PostScript values in
its NVRAM module. The printer’s IP address, unique to each printer, is stored
in a socketed ROM IC.
RAM SIMM 1 must always be a 8 Mbyte RAM SIMM. RAM SIMM 2 can be
either a 16 Mbyte RAM SIMM or a 32 Mbyte RAM SIMM.
