The Phaser 1235 Color Printer The Phaser 1235 Color Printer combines a 4-color LED-based, tandem-design print engine with an EFI image processing controller board supporting Adobe's PostScript Level 3 page description language. The controller 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. All printer versions support the color PCL5C printer language. The printer is available in three configurations: s The Phaser 1235N 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 512 Mbytes. The printer contains 136 standard, built-in fonts. The Phaser 1235N prints at a color resolutions of 600 x 600 dots-per-inch and 600 x 1200 dots-per-inch. s The Phaser 1235DT is the same as the Phaser 1235N except it includes 128 Mbytes of memory, an auto-duplexer, an internal hard drive and a lower feeder tray assembly. With the hard drive the 1235DT supports a print collation mode, a "First Page Preview" mode and a secure printjob "password" mode. s The Phaser 1235DX has all the features and capabilities of the Phaser 1235DT printers but includes 256 MBytes of RAM, two lower feeder tray assemblies and a printer station cart. The printer supports the following resolutions: s 600 x 600 dpi (Normal) s 600 x 1200 dpi (High-quality) The printer also accepts 300 x 300 dpi files from PCL legacy drivers, PCL bit map fonts, PCL bit map images, although these are imaged at 600 x 600 dpi. The resolution supported is a function of the PDL used and the feature being selected, such as Fax Friendly Black and Draft Mode. Both PostScript and PCL allow full selection of all paper sources, paper sizes, paper types and output destinations. The auto-duplexer unit (optional on the Phaser 1235N) allows the printer to automatically create two-sided prints. Print speeds depend on the chosen resolution and selected media. For resolutions of 600 x 600 (standard), in color, the printer prints at 12 pages-per-minute (ppm) on paper. Monochrome printing is at 20 ppm on paper. Transparency film printing is always 5 ppm. For 600 x 1200 dpi (enhanced) color printing, the printer prints color at the same speeds as standard mode. The printers support printing on A-, A4- and Legal-sized paper and transparency film from an adjustable tray. Optional lower tray feeders, up to two can be installed, are available. The printer features a built-in multi-sheet bypass feeder from which specialty media, cardstock and envelopes can be fed. The printer also supports manual feeding using the multi-sheet bypass feeder. 2 Phaser 1235 Network Color Printer
