Phaser 740 and 750 Color Printers
The Phaser 750 Color Printer
The Phaser 750 Color Printer combines a color laser print engine with an image
processor supporting Adobe’s PostScript Level 3 page description language. The
image processor features a bi-directional parallel interface and an Ethernet port for
host communication. The Ethernet port supports EtherTalk 10/100baseT, Novell and
TCP/IP. An optional network adapter card allow the printer to communicate with
Token Ring networks. A USB port is available on the rear panel to directly connect
with a USB-compatible host. The printer supports the color PCL5C printer language
too.
The printer is available in four configurations:
■
The
Phaser 750N
comes standard with 64 Mbytes of RAM which can be
supplemented with an additional 32-, 64- and 128-Mbyte RAM DIMM;
maximum usable capacity is 256 Mbytes. The printer contains 136 standard,
built-in fonts. The printer contains 136 standard, built-in fonts. The Phaser
750N prints at a color resolution of 1200 x 600 dots-per-inch.
■
The
Phaser 750P
is the same as the Phaser 750N except it includes 96 Mbytes
of memory and can print at a higher resolution of 1200 x 1200 dots-per-inch
(Premium mode). The Phaser 750P also support image pipelining for
greater throughput, a print collation mode (which requires the hard drive
option), and a “First Page Preview” mode.
■
The
Phaser 750DP
has all the features and capabilities of the Phaser 750P
printer but includes 128 Mbytes of RAM and a Lower Tray Assembly and
Duplex Unit.
■
The Phaser 750DX has all the features, RAM, and capabilities of the
Phaser 750DP printers but includes an internal hard drive which enables
Print Collation mode. The hard drive also is pre-loaded with manuals,
videos and printer drivers.
The color printers support a 5.3 page-per-minute, composite-black printing “Fast
Color” mode which prints at 600 x 600 dpi using three passes, cyan, magenta and
yellow, to produce an image instead of the usual four passes, cyan, magenta, yellow
and black.
Print speeds depend on the chosen resolution and selected media. For resolutions of
1200 x 600 (Enhanced), in color, the printer prints at 4 pages per minute (ppm) on
paper. Monochrome printing (Fast Monochrome) is at 16 ppm on paper.
Transparency film printing is always 2 ppm. For 1200 x 1200 (Premium) dpi color
printing, the printer color prints at 2 ppm. Monochrome printing is at 8 ppm. The
printer prints 600 x 600 dpi, composite black (CMY) draft prints at a rate of 5.3 pages-
per-minute.
The printers support printing on A-, A4- and Legal-sized paper and transparency film
from separate A or A4- or Legal-size trays. An optional two-tray second feeder (called
the Lower Tray Assembly) is available. The printer features a built-in multi-purpose
tray from which specialty media, cardstock and envelopes can be fed. The printer also
supports manual feeding using the multi-purpose tray.
