General Information

The Phaser 540 Color Printers

The Phaser 540 and Phaser 540 Plus Color Printers both combines a color laser, continuous-tone print engine with an image processor supporting Adobe’s PostScript Level 2 page description language (version 2015). The image processor features a bi-directional parallel interface for host communication. Optional network adapter cards to the image processor allow the printer to communicate on networks using LocalTalk, serial, Ethernet or Token Ring protocols. The Ethernet network card supports EtherTalk, Novell and TCP/IP. With the Token Ring network card, the Phaser 540 Plus supports Toten Ring protocols. The network cards are sometimes referred to as “smart cards” because each houses its own processor for executing speciﬁc on-board protocols; only data is transferred from the installed smart card to the printer’s image processor board.

The printers each comes standard with 20 Mbytes of RAM which can be supplemented with one or two additional 16-Mbyte RAM SIMMs. The printer contains 39 standard, built-in fonts. The printer features a SCSI-compatible interface to connect to an external hard disk drive for additional font storage. An orderable option, the Phaser CopyStation can also be connected to the printer’s SCSI port to give the printer the ability to optically copy color images.

The printer supports printing on A- and A4-sized paper and transparency ﬁlm from an A or A4-size tray. An optional two-tray second feeder (called the Lower Tray Assembly) is available. The printer also supports manual feeding. The Phaser 540 Plus also supports Legal-size paper in its Legal-size tray.

The printer prints at a user-selectable resolution of 300 dots-per-inch or 600 dots-per-inch. Color printing is at either 4 or 16 levels of color depending on the amount of memory installed in the printer. After being idle for one hour the printer switches into its Energy Star mode where it consumes less than 45 watts of power. It “awakens” upon receiving data at any of its ports. The printer also features a closed-loop image density sensor system that allows it to auto-calibrate its color imaging so printing output remains consistent over the life of the print engine and its consumable supplies.

RAM and printer capabilities

With additional RAM memory the printer’s capabilities increase:

■

With standard 20 Mbytes of RAM, the printer has a frame buffer of 16 Mbytes, an I/O buffer of 100 kbytes, an image pipeline color cache of 500 kbytes, and PostScript virtual memory of 3.6 Mbytes. With standard 20 Mbytes of RAM, the printer can print 300 dpi continuous-tone and 600 dpi bi-level images.

1-2

Phaser 540 Color Printer

With 36 Mbytes of RAM, the printer has a frame buffer of 32 Mbytes,

■

an I/O buffer of 100 kbytes, an image pipeline color cache of 500 kbytes, and PostScript virtual memory of 3.6 Mbytes. With 36 Mbytes of RAM the printer can print 300 or 600 dpi continuous-tone images and has faster data throughput. With the additional RAM in the Phaser 540 Plus, the scan-to-print start time of the Phaser CopyStation is reduced to about 65 seconds.

■

With a maximum 52 Mbytes of RAM, the printer has a frame buffer of 32 Mbytes, an I/O buffer of 1 Mbytes, and image pipeline color cache of 2 Mbytes, and PostScript virtual memory of 16.8 Mbytes.

General Information

Front panel

These front panel features are found on the printer:

■

A two-line, 24-character LCD and two LEDs

Four push buttons

■

LCD

The LCD serves two purposes: displaying current controller and print engine status information and displaying an interactive menu. Status information includes controller status such as

Printing . Print engine status includes messages such as Out of paper , Paper Jam , and Out of toner . The interactive menu can only be entered

while the print engine and controller are idle. The interactive menu allows the user to review and change certain NVRAM, I/O ports and peripheral parameters. Using the front panel to review and change parameters is discussed in Chapter 9, “Checks and Adjustments.”

Buttons

cancel an operation while in the interactive menu. The functions of Buttons 2, 3 and 4 are deﬁned by the particular menu or function being displayed on the LCD display. The bottom row of the LCD labels the current function of each button.

In addition, pressing the buttons as you turn on the printer enables certain diagnostic modes:

■

The Chapter 9 topic, “Resetting NVRAM” on page 9-9 explains how to use the front panel buttons to reset the NVRAM to its factory default values.

Button 1, the left-most button, is labeled the Exit key and is used to

Pressing and holding Button 1, as you turn on the printer, skips power-up diagnostics (except for a brief kernel test) and proceeds to PostScript startup.

Pressing and holding Button 2, as you turn on the printer, executes extended diagnostics.

Pressing and holding Button 3, as you turn on the printer, executes interactive service tests. These are described in “Printer self-diagnostics” on page 9-6.

General Information

Health LED

A health LED indicates the status of the image processor board. The health LED is mounted on the image processor board and is viewable through the grill behind the manual feed tray. (The grill is the removable RAM SIMM options cover.) Once the PostScript code is loaded into memory and the image processor is initialized and running, the image processor blinks the LED at a one-second rate.

Blinking (at a steady rate): The printer is operating normally. The LED

■

blinks irregularly during power-up self-diagnostics.

If a soft error occurs, the image processor board operates, but in a reduced capacity. Soft failures include failure of expansion memory SIMMs or any of the interface ports. When a soft error occurs, the printer automatically prints a startup page listing the error.

■

or Off : A hard error condition has occurred that would keep the

image processor board from operating.

Media tray type sensing

The combinations of the three tray sensors “tell” the print engine what type of paper tray is installed. The tray sensors are located on the left-side interior of the paper tray slot. Sensor actuators are attached to the bottom end of the tray to close the appropriate sensor. There are four tray types:

■

Letter (A-size) paper

Letter (A-size) transparency ﬁlm

■

Metric Letter (A4-size) paper

■ Metric Letter (A4-size) transparency ﬁlm

■ Legal-size paper (Phaser 540 Plus)

Test Pattern Generator

The Test Pattern Generator contains PostScript scripts to start test patterns for a number of Tektronix color printers. It allows you to test a printer as if it were receiving a ﬁle from a host computer. The test patterns are generated by the printer's image processor and then printed by the print engine.

Note

The Test Pattern Generator should contain ﬁrmware version 1.2 or higher.

Test Pattern Generator

To use the Test Pattern Generator, do the following:

Select a test pattern to be printed using the Test Pattern Generator's ﬁve DIP switches. The following tables lists the available test patterns.

Plug the Test Pattern Generator onto the printer's parallel port. Use the parallel cable adapter (013-0299-00) to convert between the Test Pattern Generator’s Centronics-style connector and the printer’s new-style, high-density parallel port connector. You do not have to turn the printer off; you can plug in the Test Pattern Generator “hot.”

Press the Test Pattern Generator's START button. Its green LED ﬂashes as you press the button.

The printer will print the transmitted print ﬁle. The front panel displays the message “Waiting for data,” with the READY light ﬂashing, for ﬁve minutes after a test print has been sent to the printer. However, you do not have to wait ﬁve minutes before sending another test print from the Test Pattern Generator; the printer will accept another test print.

Besides print ﬁles, the test pattern generator also allows you to turn off and on the printer's startup page.

Additionally, the Test Pattern Generator lets you set up a printer for printing from a 4511A Network Interface. To do so, just select the appropriate DIP switch setting.
