'''Introduction to LaserWriter Service, Version 2.0''' is Apple's general laser-printer service course, '''166 pages''', copyright 1992 and 1997 Apple Computer, Inc. The PDF was distilled on 10 January 1997.
'''''Introduction to LaserWriter Service''''', version 2.0, is Apple's general laser-printer service training course, a 166-page document, copyright 1992 and 1997 Apple Computer, Inc. The PDF's creation date is 10 January 1997.<ref name="ss">Apple Computer, Inc., ''Introduction to LaserWriter Service'', version 2.0 (1997), title page and contents, pp. 1-5. Hosted as [[:File:Introduction to Laserwriter Service 2.0 1997.pdf]].</ref> Page numbers below are the course's own, which match the PDF page numbers.


Where the LaserWriter II course teaches one printer, this one teaches the '''principles''' that apply to all of them, which makes it the single most useful document on this wiki for someone who has never worked on a laser printer before.
It teaches the principles common to all LaserWriters rather than any one model: printer features and connections, setup, how a page is described and transferred to the printer, the print engine, and a general troubleshooting method.<ref name="ss" />

The six-stage print cycle - charge, expose, develop, transfer, fuse, clean - is the framework every LaserWriter print-quality fault maps onto, and this is where it is set out.
== What it settles ==
The print cycle is set out as six stages: drum charging, image formation, development, transfer, fusing and cleaning the drum.<ref name="pc">''Introduction to LaserWriter Service'', Theory of Operation, Print Cycle, pp. 80-94.</ref> The quick checks Apple recommends before detailed troubleshooting are: power and power connection; all cables; toner cartridge fitted, not empty and with its sealing tape removed; paper cassette fitted with paper; all access doors closed; status lights; print density setting; switch settings; and whether the printer produces a user test page, which some LaserWriters have switched off in software.<ref name="qc">''Introduction to LaserWriter Service'', Troubleshooting Basics, Quick Checks, pp. 108-109.</ref>
