General Information Ten circuit board support the printer’s electronics. Four board, called I/O board 1 through I/O board 4 supports the front panel, solenoids and sensors. The main board contains the printer’s two CPU processors, a 29K processor which executes the PostScript image processing and a 68K processor which controls the print engine.

General Information An internal data bus, called the I C bus, connects all I/O boards to the main board. Through this single bus, the main board can “poll” the I/O boards for the state of the printer’s sensors as well as actuate the printer’s solenoids. This data bus greatly simpliﬁes the wiring that would otherwise be required for monitoring dozens of sensors and actuating solenoids.

Verifying the Printer and Host Connections To print to the Phaser 340 in the VMS environment, you must have the symbiont PhaserSym running on the host. To print to the printer from the host, you must ﬁrst have the printer’s queue established. This is site-dependent and requires the aid of the site’s network administrator.

Page 95: Drum/Transfix Assembly
Theory of Operation Drum/transﬁx assembly The drum/transﬁx assembly forms the key portion of the printer where imaging takes place. The main features of the drum/transﬁx assembly are its drum and transﬁx roller. In operation, the image to be printed on paper is ﬁrst “printed” on the rapidly rotating drum.
Page 96 A closed-loop servo drive system is inherently dangerous. Since the motor speeds up if it senses the drum drive system slowing down, ﬁngers caught in the drum belts and gears can be severely injured. Phaser 340 Color Printer...
Page 97: Maintenance Tray
Theory of Operation Maintenance tray The maintenance tray performs two functions. It’s primary function is to apply a thin coating of releasing agent, a silicon oil, 5 millionths of an inch thick to the surface of the drum prior to printing. The releasing agent keeps the ink from sticking to the drum’s surface and facilitates its transfer to the sheet of paper or transparency ﬁlm.
Page 98 The sensors are mounted on the maintenance tray guides on the inside of the printer frame. Phaser 340 Color Printer...
Page 99: Printhead
Theory of Operation Printhead The printhead is the heart of the printer. The printhead spans nearly the length of the drum. Using its 352 ink-jet nozzles (88 jets for each primary color), with just a horizontal motion of slightly less than 5 mm (0.2 inches), the printhead can print the entire image on the rotating drum.

Page 101: Figure 5-7 X-Axis Printhead Movement During Printing
Theory of Operation X-axis or lateral movement of the printhead is accomplished by a short-pull pulley system. Through a stiff, yet ﬂexible band, the x-axis motor pushes on the end of a lever arm which, in turn, pulls the x-axis shaft. The printhead, mounted to the x-axis shaft, slews laterally across the surface of the drum.

Page 103: Ink Loader
Theory of Operation Ink loader The ink loader consists of four parallel channels with an ink melting element at the end of each of the four channels. Ink sticks, one color loaded in each channel, are pressed by coil-spring pressure into the melting elements. As ink is required by the printhead, the appropriate color’s melting element is activated and the end of the ink stick is melted.
Page 104: Cap/Wipe/Purge Assembly
When servicing the printer be careful of the cap/wipe/purge assembly as it passes the printhead. If a damaged wiper blade of cap/wipe/purge assembly catches on the printhead it could ﬂip hot liquid ink upward into your face. 5-12 Phaser 340 Color Printer...
Page 105: Figure 5-11 The Cap/Wipe/Purge Assembly And Vacuum System
Theory of Operation Vacuum for the purge cycle is obtained from a vacuum pump and a vacuum accumulator. A small vacuum pump, running for about 75 to 90 seconds, creates a strong vacuum in the vacuum accumulator. Then an air valve is energized for a fraction of a second, exposing the printhead faceplate to the strong, accumulated vacuum to suck debris and bubbles out of the printhead nozzles.

Page 117: Figure 5-17 Printing The Latent (Pre-Transfer) Image On The Drum (Later Printers)
Theory of Operation For transparency printing, the image is printed in the same manner. However, the image is printed twice on the drum, the second image positioned precisely over the ﬁrst image before being transferred to the sheet of transparency ﬁlm; this increases image density.
Page 118: Paper Pick
At this point, the process motor is stopped to wait for more ink deposition on the drum. 5-26 Phaser 340 Color Printer...
Page 119 Theory of Operation When ink deposition is about 95% complete, the process motor is activated to bring the sheet of paper through the paper pre-heater and to the transﬁx position. The paper preheater heats the paper to improve ink transfer. The leading edge of the sheet of paper trips the paper preheater exit sensor as it passes out of the paper preheater.

These actions are used in different combinations for three different types of cleaning cycles: quick wipe short cleaning long cleaning The long cleaning is described here. The short cleaning and the quick wipe are basically subsets of the long cleaning cycle. 5-30 Phaser 340 Color Printer...
Page 123 Theory of Operation Preparation. Following printer power-up from a cold start or in response to a front panel menu selection, the print engine begins a printhead long cleaning cycle. The ﬁrst step is to stop any ink melting operation. Next, the main board starts the heaters in the cap/wipe/purge assembly.

Page 125: Paper Preheater Cleaning
Theory of Operation Paper preheater cleaning This is a customer-initiated cleaning procedure, selected through the front panel cleaning menu Clean: Ink Smears. The purpose of this cleaning item is to clean ink out of the paper pre-heater that may have been deposited there. Ink can be deposited in the paper pre-heater if a sheet of paper with ink on it was rerun through the printer in an attempt at two-sided printing, which is not allowed.
