Page 2: General Information
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.
Page 3: Printer Overview
(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.
Page 4: 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.

Page 36: Connecting The Printer
Installing the Printer and Drivers Connecting the printer Printer ports The printer is shipped standard with a bi-directional parallel port and a SCSI port for interfacing to the optional Phaser Copystation, or an external hard disk for font storage. In addition, the printer can be conﬁgured with optional networking and serial ports.
Page 37: Parallel Connection
To connect to the printer’s parallel port, a high-density bi-directional parallel cable is required. This cable is available from most computer cable vendors, and also as Tektronix part number 012-1468-00 (36-pin high-density printer to 25-pin DSUB PC cable). The printer supports a standard (uni-directional) parallel port. The parallel port can also be set for bi-directional communications.

Page 97 Theory of Operation Printhead The printhead is the heart of the printer. It is the device that actually places ink onto paper. The printhead contains the reservoirs for the ink it uses as well as a series of piezo-electric devices that squirt ink onto the paper. The printhead features 124 jet nozzles to force ink out of the printhead onto paper.
Page 98 Theory of Operation The core of the Phaser 600 printhead is the “jet stack” — a bonded pack of 14 etched stainless steel plates The active element in the jet stack is the piezo-electric crystal array that, when energized, ﬂexes to force a drop of ink out of a jet.
Page 99: Print Modes
Theory of Operation The printhead’s ink ﬂow from the supply chamber to the nozzle is signiﬁcantly different than aqueous printers. The ink in the Phaser 600’s printhead ﬂows past the piezo crystal and then to the ink jet oriﬁce (nozzle).

Page 101: Maintenance Station
Theory of Operation Maintenance station Like ink-jet printers, the printer requires a maintenance station to keep the printhead jets working.

Page 105 Theory of Operation Fuser After ink is deposited on the media it must be fused. Fusing increases the diffusion of ink droplets into the media and improves appearance and durability of the image. Using the printer driver, uses have the option of hot fusing, via a built-in heater element, cold fusing and no fusing at all, depending on the media being printed on and user preferences.
Page 106: Power Supply
The engine control board contains the drivers for the X-axis, Y-axis and fuser motors, the printhead heaters, and the fans. Lastly, the engine control board contains the A/D converters for controlling the printhead temperatures, monitoring power supply output, ink levels in the printhead and the fuser’s temperature. 5-12 Phaser 600 Color Printer...
Page 107: Print Process In Operation
Theory of Operation Print process in operation Media positioning The print process is preceded by the printer positioning and measuring the roll or sheet of media currently installed. When the paper input sensor detects a sheet of media inserted up to the upper feed rollers, the clamp-close solenoid are energized to close the spring-loaded clamp against the drum.
Page 108 ﬁrst inserted at the upper feed rollers. This way, new media can easily be exchanged for the currently installed media 5-14 Phaser 600 Color Printer...
Page 109 Theory of Operation Printing Printing begins with the same process described in the media positioning except the media is not unloaded. Also the clamp-close solenoids remain energized to hold the leading edge of media to the drum. The drum incrementally steps forward to allow the shutting printhead to print the image in swaths upon the paper.

Page 111: Troubleshooting
Chapter Troubleshooting This chapter discusses troubleshooting the 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.
Page 112 The printer continues to heat the printhead to its normal operating temperature. A printhead cleaning cycle is performed once the printhead reaches its normal operating temperature. Once the cleaning cycle completes, the print engine is initialized. Phaser 600 Color Printer...
Page 113: Print Engine Troubleshooting
Troubleshooting Print engine troubleshooting 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 If the printer does not power up, or does not initialize, or the printer initializes but the motors do not run properly, go to the later topic, “Verifying power supply operation”...
Page 114: Verifying Print Engine Operation By Using Its Test Print
AC Input: With the VOM set to measure AC voltages, measure the power being supplied to the printer. It should measure between 85 to 132 VAC (110 VAC nominal) or 180 to 264 VAC (220 VAC nominal). Phaser 600 Color Printer...

Page 117: Testing Motor And Solenoid Resistances
Troubleshooting Testing motor and solenoid resistances Turn off the printer and disconnect the power cord. With a VOM set for measuring resistance, test each motor's windings for correct resistance (disconnected from the printer). Rotate the motor's drive shaft slightly while taking the measurement. Also carefully inspect each motors wiring harness to ensure it is not damaged and shorting out to the chassis.
Page 118: Media Jams And The Paper Path
“Testing for a shorted motor” on page 6-6. Otherwise, go to Step 4. Refer to the later topic, “PC-based diagnostics” on page 6-26. Use the motor and solenoid test to check the operation of the paper load system. Phaser 600 Color Printer...
Page 119 Troubleshooting Print feed jams -- internal jam error Paper feed jams, noted as internal jams, occur if the left or right of the paper is less than 8 mm (1.3 in.) from the respective end of the drum, or the left or right edge of the media cannot be detected at all by the printhead’s left and right paper-edge sensors.

Page 121: Printing And Print Quality Problems
Troubleshooting Exit jams An exit jam occurs when the media has not been detecting exiting the printer when it should have. Ensure the media being used is in good shape, with not torn or ragged edges that could jam in the paper path. Inspect the paper path for obstructions.

Page 123 Troubleshooting Streaks or lines in the print parallel to the printhead travel Possible missing weak jet. Print the Service Test Print 2 “Weak Jet” to determine if a jet is not performing. Perform a printhead cleaning cycle to try to clean a clogged jet. If necessary, turn off the printer and allow the printhead to cool for 3 hours.

Page 125 Troubleshooting Inconsistent printing This failure is probably caused by an electronic failure. Possible causes are a poor electrical connection at the carriage board an engine control board failure or a poor ground. Also check the printhead drive voltage; see Chapter 9, “Printhead drive voltage adjustment” on page 9-15.

Page 127 Troubleshooting If the problem persist, a “freeze/thaw” cycle may remove the obstruction. Turn the printer off and allow it to cool for at least 3 hours. Then turn it on again. During the cycle, ink in the nozzles solidiﬁes and is forced out by expanding ink when the ink is remelted. Purge three times after a freeze cycle, if necessary.

Checks and Adjustments Printhead drive voltage adjustment The voltage used to drive the printhead’s piezo-electric crystals is unique to each printhead. Each printhead’s required voltage is printed on the back of each printhead. Generally, once the voltage is set for a printhead, it is not changed. It may, in rare cases, be changed as the printhead ages.
