Service Manual

Phaser 340 overview

The Phaser 340 Color Printer is an Adobe PostScript Level 2 color, solid ink-jet printer with Tektronix color matching extensions (TekColor 3.0). The Phaser 340 is marketed in two variations: The Phaser 340 and the Phaser 340 Plus (also called Phaser 340 with Extended Features). Externally and mechanically, the Phaser 340 and Phaser 340 Plus are identical. The startup page indicates whether the printer is a “Plus” model. Additionally, the Macintosh printer driver indicates if the printer is a “Plus” model.

Note

The Phaser 340 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 12 Mbytes. The Phaser 340 Plus prints at an addressability of 600 x 300 dots-per-inch or 300 x 300 dpi, features 69 built-in fonts, and comes with 24 Mbytes of RAM. The Phaser 340 Plus is also capable of job pipelining; it can print one image and process the data for the next image at the same time.

Both printers feature two available paper trays: A and A4, with an optional 500-sheet high-capacity Lower Paper Tray Assembly which gives the printer a dual-tray capability. (The Lower Paper Tray Assembly is sometimes referred to as the second feeder; it only supports paper printing.) The printers print images on A- and A4-size paper and transparency ﬁlm with 5 mm (0.2 in.) margins; the bottom margin is 7 mm (0.3 in). Each can print up to a rate of four pages per minute; although the Phaser 340 Plus has greater image processing capabilities for faster image throughput. Both variations feature a SCSI port to support an external SCSI disk for additional font storage and the Phaser CopyStation copier option.

Unless otherwise noted, descriptions and servicing are identical for the Phaser 340 and the Phaser 340 Plus.

Early in 1996, Tektronix introduced a signiﬁcantly redesigned Phaser 340 and Phaser 340 Plus, denoted by the serial numbers

xxxx, BDx xxxx, BEx xxxx, B6E xxxx and B6F xxxx . These

BCx printers are often referred to as Version 2 printers. Theses printer feature some new FRU components that are not compatible with older printers. These printers also have an updated front panel menu structure with new menu items.

A 68K processor oversees print engine operations; the printer’s PostScript image processor is powered by a 32-MHz 29K RISC processor. The printer features an integral bi-directional parallel port. A rear panel slot allows customers to install one “smart card” Phaser Share Network Card. One version card provides an RS-232C serial port and a LocalTalk port. A second, alternative card offers an Ethernet port which includes support for EtherTalk, Novell NetWare and TCP/IP. A third card provides a Token Ring interface supporting Novel NetWare, TokenTalk, and TCP/IP. TCP/IP protocol support is standard in printers serial-numbered BCxx supported via a downloaded software key in earlier printers (Version 1 printers).

Phaser 350 overview

The Phaser 350 Color Printer is a signiﬁcant improvement over the Phaser 340. Foremost among the Phaser 350 Color Printer’s features is its 6 page-per-minute FastColor print mode. The print mode is selectable through the front panel and from printer drivers. Other features are: The ability to set the printer’s IP address easily from the front panel, a multi-page print collation mode (hard disk required), and PrintCheck which lets you preview the ﬁrst print of a muliple copy job before letting the printjob continue. The front panel features the printer name and status information similar to the Phaser 550.

The Phaser 350 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 24 Mbytes. The Phaser 350 with the Extended Featues option prints at an addressability of 600 x 300 dots-per-inch (Enhanced) or 300 x 300 dpi (Standard), features 69 built-in fonts, and comes with 24 Mbytes of RAM. The Phaser 350 with Extended Features is also capable of job pipelining; it can print one image and process the data for the next image at the same time.

Version 3.0 Ethernet and TokenRing cards add support for Telnet and ftp, and PhaserLink allows users to monitor and control the printer via an internet browser.

Print engine exchange

In extreme situations it may be necessary for service personnel to exhange the entire print engine, while transferring the main board which maintains purchased options and network identity at the customer’s printer.

The two printer modules for this exchange program are:

650-3260-00 supports Phaser 340s serial-numbered B1xxxxx through

■

B9xxxxx, except B6Exxxx and B6Fxxxx.

650-3184-01 supports Phaser 340s serial-numbered BCxxxxx through

■

BExxxxx and B6Exxxx and B6Fxxxx. It also supports all Phaser 350s.

The 650-3260-00 engine is a 2:1 jet interlace chassis; the 650-3184-01 is a 4:1 jet interlace chassis shipped with two front panel logos so the proper one can be installed.

Accessing the printer’s web page

For printers serial-numbered BCxxxxx and up and the Phaser 350. PhaserLink,

the Tektronix implementation of a World Wide Web server inside the printer, allows a customer to communicate to the printer using a web browser. With PhaserLink, a customer can view and set printer and networking parameters. A homepage built into the printer links the printer to other homepages such as the Tektronix World Wide Web home page.

To view the printer’s homepage, the printer must be connected to a network supporting TCP/IP protocols and be assigned an IP address. Refer to the

PhaserShare Network Cards and Software User Manual .

PC-based diagnostics

The PC-based diagnostics allows you to interactively test and check the operations and functionality of the printer. The diagnostics are provided on a 3-1/2 inch ﬂoppy diskette. All of the diagnostic tests are started from the PC. Some of the tests are stored on-board the main board in ROM and are merely started by the PC-based diagnostics; other tests are downloaded to the printer from the PC. The test are functionally divided into two classes: 29K tests, which execute test stored in the 29K processor’s ROM and the 68K tests which are downloaded to the printer to test the 68K processor and the print engine.

The PC diagnostics were developed to run on a PC. The diagnostics are used with an Apple® PowerBook® running PC emulation software as this is the portable computer in use by Tektronix Field Service.

Note

Printers serial-numbered B0xxxxx to BB xxxxx use diagnostics version 1.24. Printers serial-numbered BCxxxxx and up use diagnostics version 2.40. Both diagnostics are available on the same diskette. Printers B0xxxxx to BBxxxxx may receive a ﬁrmware upgrade, upgrade kit Z340PL, revising the ﬁrmware to 2.40R. The “R” is visible only on the ROM’s label, not on the printer’s startpage. These printers require version 2.40R or 2.40RA diagnostics.

A future release of the diagnostics is planned that will automatically select the correct version when the diagnostics are started.

Service Manual

Jet interlacing

Phaser 340 color printers serial numbered BC xxxxx and later and Phaser 350 printers use a different method of laying ink onto the drum; they perform a “four-jet interlace.” As the drum reaches the correct speed of 176 rpm, the ink-jets begin to ﬁre to deposit the image on the oiled portion of the drum. As the jets ﬁre, the printhead slews in the x-axis to complete the image on the drum. When the ink image is about 80% complete, the paper-pick cycle begins.

For 300 dpi printing, each jet lays down 28 pixel columns. Each jet lays down one pixel column for each drum rotation (28 revolutions total). Each jet travels horizontally the distance of 112 pixels to lay down its 28 pixel columns within that 112 pixel-wide ﬁeld. The 112 pixel-wide ﬁeld of each jet overlaps the 112 pixel-wide ﬁeld of six other jets; this is where interlacing occurs. To lay down its 28 pixel columns, each jet follows this sequence:

Print 1st column, step four columns to the right, print 2nd column, step four columns to the right. Repeat until 7 columns are laid down.

Step 2 additional columns to the right. Print the 8th column, step 4 columns to the right, print 9th column,

step 4 columns to the right. Repeat until 7 columns are laid down (total of 14 so far).

Step 1 additional column to the right. Print the 15th column, step 4 columns to the right, print the 16th

column, step 4 columns to the right. Repeat until another 7 columns are laid down (21 total so far).

Step 2 additional columns to the right. Print the 22nd column, step 4 columns to the right, print the 23rd

column, step 4 columns to the right. Repeat until the last 7 columns are laid down for a total of 28 pixel columns.

The intermediate 2-step, 1-step and 2-step movement between the 7th and 8th pixel columns, the 14th and 15th columns, and the 21st and 22nd columns, respectively, allow the 28 pixels columns of each jet to properly interlace with the 28 pixel columns of the other jets it is combined with. A total of 2,432 columns, each 3,134 dots tall, are laid down.

The advantage of this print method is that variability between jets is “averaged out” by being interlaced with three other jets. As shown in the illustration, of the 28 pixel columns printed by any single jet, only two of its pixel columns are actually ever adjacent. Usually they are separated by three other pixel columns produced by other jets, hence the name spacing between jets and the 112 pixel-wide ﬁeld that each jet travels, the pixel columns of any one jet actually interlaces with the pixel columns of six other jets, although no more than four at any one time.

four-jet interlace . Because of the 28 pixel

In reality, because of the ﬁxed width of the printhead and inter-jet spacing, the outermost jets cannot interlace completely with their adjacent jets. In this case, the drum rotates for seven extra imaging rotations (14 if both end jets are needed) for the printhead to reposition the end jets so they can ﬁll-in the missing pixel columns that cannot otherwise be interlaced.

Phaser 340 and 350 Color Printers

For transparency printing, the image is printed in the same manner. However, the image is printed, with smaller droplets, 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.

For 600 x 300 dpi printing, each jet lays down 56 columns of ink drops spread over a 224 pixel-wide ﬁeld. The drum rotates 56 times to receive the pixel columns. The same interlace method is used, except 14 pixel columns are printed between the intermediate 2-step, 1-step and 2-step movements. A total of 4,864 columns, each 3,134 dots tall, are laid down. The x-axis motor steps at half the rate to double the resolution in the x-axis. Also, the printhead jets output smaller, 600 dpi dots.

Service Manual

Enabling TCP/IP with the authorization code

TCP/IP protocol support is standard in Phaser 340 printers serial-numbered

xxx and up and Phaser 350 printers. This feature depends upon the version

BCxx of ﬁrmware on the PhaserShare card being 2.0 or higher. TCP/IP protocol is optionally supported via a downloaded software key in earlier printers.

When the Phaser Share Ethernet card is installed, the EtherTalk and Novell protocols are immediately active. For printer’s serial numbered B1xxxxx through B9xxxxx, the Ethernet card’s TCP/IP protocol must be activated by a downloadable authorization code, sometimes referred to as its software key. The authorization code is printed on a certiﬁcate included with the printer (if the option was factory-installed) or with the ﬁeld upgrade kit. The

Bypass mode

Bypass mode allows you to access the front panel menus (bypassing the engine and PostScript initializing processes) without having to wait for the printhead to warm up. This way, you can reset NVRAM or read fault codes immediately. Meanwhile, the printer continues to warm-up and initialize “in the background.” Even if the engine faults, bypass mode can be active.

Press and hold front panel buttons 1 and 2 (left two buttons). Turn on the printer.

Wait for the message Entering Bypass Mode to be displayed (about 40 seconds).

Release buttons 1 and 2. For the Phaser 350, do not press buttons 1 and 2 until the ﬁrst “Warming Up” message is displayed, then quickly press the buttons and hold for a few seconds until “Entering Bypass Mode” is displayed.

Cool down mode

Phaser 340 printers serial-numbered BCxxxxx and up and Phaser 350 printers have a menu item that accelerates the cooling of the printhead.

Enter the extended menu by pressing Menu and Exit .

Scroll to the Service Suppor t menu item and press Menu.

Scroll to the item Cool-down for Power Off and press OK .

The printer turn off all the engine heaters and runs the fans on high until the ink in the printhead has solidiﬁed. Then the printer’s front panel informs you the printer can be turned off.

During power-on initialization, the engine is unable to disengage the process motor. Prior to declaring this fault, the engine has attempted to move the process motor through enough revolutions to disengage the head tilt mechanism, but the motor stalled. The X axis was then displaced to the right 0.15 inches and the disengage was repeated, but the motor stalled again. This fault is then declared. The head is unable to move on its tilt axis, perhaps because it is colliding with something (head restraint pin, cap, poorly installed ink loader, screwdriver.)
