The '''Apple Service Guide for LaserWriter Printers, Volume I''' is Apple's pocket on-site service guide for its first two generations of laser printers: the '''LaserWriter and LaserWriter Plus, the LaserWriter II SC/NT/NTX/IIf/IIg, and the Personal LaserWriter SC/NT/LS'''. Apple's part number is '''072-0631-B''' and the running footer throughout is ''ASG-LaserWriter Printers Jan 92''.
The '''LaserWriter Printers Service Guide, January 1992''' is a scan of Apple's on-site service guide for the LaserWriter and LaserWriter Plus, the LaserWriter II SC, NT, NTX, IIf and IIg, and the Personal LaserWriter SC, NT and LS. The cover of this copy reads "LaserWriter Printers Service Guide, January 1992"; the running footer is "ASG-LaserWriter Printers Jan 92". It is a 217-page scan made in 2016.<ref name="asg">Apple Computer, ''LaserWriter Printers Service Guide'', January 1992, 217 pp. (scan). Hosted as [[:File:Apple Service Guide LaserWriter Printers January 1992.pdf]].</ref> It is the same guide as [[Apple Service Guide For Laserwriter Printers Volume I 072-0631-b 1992]], part number 072-0631-B, scanned separately.


Unlike the ''Service Source'' volumes it condenses, the Apple Service Guide was written to be carried to a customer site, and each printer gets a short self-contained booklet with the same headings.
== Contents ==
Safety procedures and practices, then six tab sections; page numbers restart in each tab.<ref name="asg" />
* Safety procedures and practices (PDF p. 5)
* Tab 1, On-Site Troubleshooting (PDF p. 9)
* Tab 2, LaserWriter/LaserWriter Plus (PDF p. 16): exploded view, parts list, specifications, status lights, test prints, troubleshooting (pp. 10-51), ROM upgrade, laser power and image skew adjustments, preventive maintenance, wiring diagram
* Tab 3, LaserWriter II (PDF p. 78)
* Tab 4, Personal LaserWriter (PDF p. 140)
* Tab 5, General Information (PDF p. 196): connecting to a Macintosh or an MS-DOS computer, hard disks on the LaserWriter II NTX
* Tab 6, Ports and Cables (PDF p. 204): cable table, external connectors and pin-outs, switch configurations


== Contents of each printer's booklet ==
For a fuller description of each tab, see [[Apple Service Guide For Laserwriter Printers Volume I 072-0631-b 1992]].
* Exploded View (p. 2)
* '''Parts List''' (pp. 3-4)
* Major Assemblies (p. 5)
* I/O Board Identification (p. 6)
* Specifications (p. 7)
* '''Status Lights''' (p. 8)
* Test Prints (p. 9)
* Troubleshooting (pp. 10-51)
* LaserWriter Plus ROM Upgrade (pp. 52-53)
* '''Laser Power Adjustment''' (p. 54)
* '''Image Skew Adjustment''' (pp. 55-56)
* '''Preventive Maintenance''' (pp. 57-60)
* '''Wiring Diagram''' (p. 61)
 
Page numbering restarts within each booklet, so cite the printer and the booklet page rather than a PDF page number.
 
The guide also carries Apple's on-site information-gathering checklist, its safety pages (high-voltage warning, invisible laser radiation warning, toner safety, ESD rules) and instructions for connecting to a Macintosh and to an MS-DOS computer.

Apple says so itself, in the guide: ''"The following parts list is not comprehensive. Only selected service modules and replacement parts are listed. When ordering a replacement module or spare part, be sure to check the part number in the guide against the current price pages in the Apple Service Programs manual."'' So the part numbers here are '''a selection, and possibly superseded'''. There is '''no schematic and no component-value list'''; the wiring diagram shows interconnection only. It is a condensation, and Apple states it does not replace the Apple Service Technical Procedures or ''Service Source''.
Apple's parts lists are "not comprehensive": only selected service modules and replacement parts are listed. There are no schematics or component values.<ref name="asg" />
 
== Three pages, one document ==
This is a '''third scan''' of the same January 1992 guide. Its cover reads ''LaserWriter Printers Service Guide January 1992'' without "Volume I" - Volume II did not exist until September 1993 - but the running footers (''ASG-LaserWriter Printers Jan 92'') and the contents match the other two copies:
* [[Apple LaserWriter Printers Volume I]]
* [[Apple Service Guide For Laserwriter Printers Volume I 072-0631-b 1992]]
