Phaser 340 overview

2 Phaser 340 and 350 Color Printers
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 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
BCx xxxx, BDx xxxx, BEx xxxx, B6E xxxx and B6F xxxx . 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 an 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 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.
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 xxx and up. TCP/IP protocol is optionally
supported via a downloaded software key in earlier printers (Version 1 printers).
