K Service Source LaserWriter 8500 K Service Source Overview LaserWriter 8500 Overview About This Overview - 1 About This Overview This overview briefly describes the servicing issues of the LaserWriter 8500, especially those that distinguish it from earlier Apple laser printers. 360 Degree View LaserWriter 8500 Basic Configuration Overview General - 2 General The LaserWriter 8500 is a 600 dpi, 20 ppm monochrome laser printer that is capable of printing onto paper up to 13 x 20 inches in size. In its basic configuration, the printer has a capacity of 650 sheets, the standard cassette holding 500 sheets (as compared to the 250 typical in earlier printers), the multipurpose tray holding 150. There are several options available for the printer, including a duplexer unit (for two-sided printing), a 500sheet feeder, and an envelope cassette. LaserWriter 8500 with Duplexer and Sheet Feeder 360 Degree View Overview Duplexer - 3 Duplexer The duplexer is an inverted L-shaped feeder that mounts onto the upper rear of the printer. Once installed, all paper (even simplex) diverts into and exits from the duplexer. This is unlike the LaserWriter 12/640 PS, which employs a solenoid-actuated diverter controlled through software. The operative element in the LaserWriter 8500 is the exchange chute, located in the fuser assembly. The exchange chute is actuated (i.e. locked in place) during installation of the duplexer. After the first pass of a duplex page, the paper partially exits the duplexer delivery rollers. The rollers then reverse and the paper feeds back down through the duplexer and into the printer engine, in preparation for imaging of the second side. The paper then exits through the duplexer into the delivery tray. Duplexer Paper Path Through Duplexer Overview Paper Path - 4 The duplexer derives its power from the printer engine but has its own motor to generate mechanical drive. Offset Function The duplexer has a job separation feature that allows print jobs to be stacked offset (i.e. staggered left-to-right) in the delivery tray. Job separation is set in the Apple Printer Utility. Note: Due to cost considerations, the offset function has been incorporated into the duplexer instead of the printer engine. Offsetting and duplex printing are otherwise unrelated to one another. The offset motor in the duplexer generates the mechanical drive for offsetting paper. Overview Sheet Feeder - 5 Sheet Feeder As with the LaserWriter 16/600 PS and LaserWriter 12/ 640 PS designs, the sheet feeder fits squarely beneath the printer to form a dual front-loading cassette arrangement. Unlike those models, however, you can stack two feeders beneath the printer, for a total auxiliary capacity of 1000 sheets. Also unlike those models, the sheet feeder and the engine use identical cassettes in the LaserWriter 8500. The sheet feeder derives its power and mechanical drive from the printer engine.
