Service Guide

Phaser 780 overview
The Phaser 780 Color Printer combines a color laser, continuous-tone print engine with an image processor supporting Adobe’s PostScript 3 page description language. The image processor features a bi-directional parallel interface and a 10baseT Ethernet port for host communication. Optional network adapter cards to the image processor allow the printer to communicate on networks using LocalTalk, Ethernet 100baseT or Token Ring protocols. The Ethernet network card supports EtherTalk 100baseT, Novell and TCP/IP. With the Token Ring network card, the printer supports Token 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 PCL printer language is also supported.
The printer is marketed in three versions:
Phaser 780 N
The printer contains 136 standard, built-in fonts. The standard Phaser 780 prints at a resolution of 600 x 600 dots-per-inch on A and B-size media. The base printer does not support grayscale printing.
Phaser 780 GN
The 600 x 1200 dpi. It also contains 136 fonts. The graphics printers supports 16 level grayscale printing as well as printing oversize-B images.
Phaser 780 P
The features as the GN printer. In addition, the Plus version Phaser 780 supports image pipelining for greater throughput, a print collation mode, and a “check print before proceeding with job” mode. The plus printer also feature a SCSI­compatible interface to connect to an external hard disk drive for additional font storage. The hard disk drive is also required for print collation of multiple copy multi-page prints. A scanner can also be connected to the Plus printer’s SCSI port to give the printer the ability to optically copy color images.
RAM memory in the printers can be supplemented with one or two additional 32­, 64-, or 128-Mbyte RAM DIMMs; the maximum usable capacity is 192 Mbytes
Print speeds depend on the chosen resolution and selected media. For r esolutions of 600 x 600 (standard), in color, the printer prints at 4 A-size pages per minute (ppm) on paper . Monochrome printing (Fast Monochr ome) is at 16 ppm on paper . Transparency film printing is always 2 ppm.
The printers support printing on A-, A4-, A5-, B-, B4, B5, SRA3, A3-, 13 x 19 in. and Legal-sized paper from a 250-sheet tray. An optional three-tray second feeder (called the Lower Tray Assembly) is available with additional 250-sheet standard media trays. 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.
(Standard) comes standard with 64 Mbytes of RAM. The
(Graphics) features 96 Mbytes of RAM and can print at
(Plus) features 192 Mbytes of RAM and supports the same
After being idle for the selected amount of time 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.

Phaser 780 Color Printer
Memory considerations
The base printer features 32 Mbytes of RAM in one connector and features two additional DIMM connectors which accept 16-, 32-, 64-, or 128 Mbytes RAM DIMMs. The printer can use any off-the-shelf RAM meeting these specifications:
168 pin DIMM
Synchronous DRAM
3.3 volt
9 nsec speed
Valid on-board Serial Presence Detect ROM.
Upon power-up, the image processor interrogates the 256 byte Serial Presence Detect ROM which describes the DIMM in great detail, with details such as data width, clock delay, number of address columns and row, refresh rate and more. If the DIMM does not meet the required specifications it will be ignored; no error message will be reported.
With more memory the printer gains the capabilities of printing at higher resolutions, printing without having to use image compression (which trades off less installed RAM for longer image processing time) and dual frame buffers for printing one image while processing a second image (which gives greater printing throughput). With additional RAM memory, the printer’s capabilities increase as detailed in the following table:
