Page 5: Shipping The Printer
Caution To keep your warranty valid, the printer must be shipped in its Tektronix shipping box, taking reasonable care to repack it properly. Failure to do so will result in damage to the printer. Remove the paper tray and repack it for shipping: Insert the two small foam shipping blocks into the paper tray on either side of the metal plate.
Page 6 Use the two tie-wraps to secure the block to the paper clamp bar. Attach them on the right-hand side where there is open space beneath the paper clamp bar. Make sure that they are tightly secured. 8849-71 Phaser 480 Color Printer...

The Phaser 480X also has a greater RAM memory capacity. Unlike the Phaser 480, the Phaser 480X can use 32 Mbytes SIMMs in the ﬁrst three of its four RAM SIMM connectors, giving the Phaser 480X a potential total RAM memory capacity of 112 Mbytes.
Page 11: Sublimation Dye Printing
Sublimation dye printing Dye sublimation printing is an extension of thermal wax transfer printing. Many of Tektronix’ current and previous 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.

Figure 5-1 is a block diagram of the printer. It illustrates how the printer is divided into two main parts: the print engine and the image processor. The following topics describe these two parts in detail. Phaser 480 Color Printer...
Page 73: Print Engine
Theory of Operation 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.
Page 74: Continuous-Tone Printing
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. Phaser 480 Color Printer...
Page 75: Creating Colors
Theory of Operation 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 and cyan. First the yellow raster making up the image is printed, then the magenta raster is printed, and ﬁnally, the cyan raster.
Page 76: Engine Control Board Block Description
The head controller generates variable length strobes. 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 ﬁxed at about 24 VDC. Phaser 480 Color Printer...
Page 77: Thermal Head
Theory of Operation Thermal head The thermal head is the device that sublimes wax dots onto the paper. It contains a row of 3584 solid-state heating elements. The actual number of elements used during a particular print depends on the paper size (A or A4, B or A3) and the image to be printed.

Page 83: Print Positioning And Printing
Theory of Operation Print positioning and printing With the paper into the paper path, the paper clamp bar, pulling the sheet of paper, is shuttled to a point just in front of the thermal head. This is the print start position. The thermal head, in turn, is lowered to sandwich the transfer roll and paper between the thermal head and the platen.
Page 84: Exit Positioning
Then the paper advances in the paper path to a position that places the trailing edge of the print at the beginning of the exit path. Exit path Trailing edge 8850-20 Figure 5-9. The printing cycle - exit positioning 5-14 Phaser 480 Color Printer...

Troubleshooting Verifying power supply operation Required tools ® #1 POSIDR IV screwdriver Volt-ohm-meter (VOM) Verifying the operation of the power supply involves four steps: Measuring the input voltages Inspecting the power supply fuses Measuring AC supply voltage Turn off the printer and unplug it from its power outlet. With the VOM set to measure AC voltages, measure for power being supplied to the printer.
Page 93: Media Jams And The Paper Path
Troubleshooting Media jams and the paper path Required tools ® #1 POSIDRIV screwdriver Jams fall into the following four categories: Media-based problems Paper-picking errors Paper-clamping errors Paper-ejecting errors Media-based problems Check that the correct type of media is being used. Be sure that the printing side of the paper faces down in the tray.
Page 94: Paper-Clamping Errors
Troubleshooting Check that the pick roller is being rotated. If it is not, go to the topic “Checking the paper-feed and drive train” on page 6-7. Otherwise, go to Step 5. In their starting position, the pick rollers' ﬂat side should face down.
Page 95: Print-Eject Jams
Troubleshooting Print-eject jams Inspect the paper eject sensor. Check to see if the upper eject roller drive belt does not rotate due to a broken drive gear. In such a case, the upper roller will not rotate when the lower roller rotates. Check that the exit roller rotates smoothly.

Page 98: Image Is Offset Or Cut Off
Troubleshooting Ensure that the thermal head fans runs during printing to keep the thermal head from overheating during printing. The fans, mounted at the rear of the top cover, blow outward. If the fans do not run, replace the print engine. If the voltage supplied to the thermal head is correct and the DIP Switch 2 setting is correct, then replace the print engine If printing still does not improve, replace the print engine.
