Phaser 340 overview

1-2 Phaser 340 Color Printer
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.
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 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 number
BCx xxxx and higher. These 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 a updated
front panel menu structure with new menu items.
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 up to 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 features 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 better image throughput. Both variations feature a SCSI port to support an
external SCSI disk for additional font storage and the Phaser CopyStation copier
option.
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 card provides an RS-232C
serial port and a LocalTalk port. A second, alternative card offers an Ethernet
port which includes standard support for EtherTalk and Novell NetWare.
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 BC01 xxx and up. TCP/IP protocol is optionally supported via
a downloaded software key in earlier printers.
