	The '''Apple Service Guide for LaserWriter Printers, Volume 2''' is Apple's September 1993 field-service booklet for the LaserWriter Pro 600/630, LaserWriter Select 300/310 and Personal LaserWriter 300. Apple wrote it for certified technicians working at the customer's site, and it condenses material from the Service Source CD and other service publications.<ref name="intro">Apple Computer, Inc., ''LaserWriter Printers, Volume II'' (''Apple Service Guide''), September 1993, title page and Introduction, p. 1 (PDF pp. 1, 7).

	~~== Contents ==~~
	~~Page numbers are the guide's own; add six for the PDF page.<ref name="toc" />~~
	* Introduction and Safety (pp. 1-6): LaserWriter safety rules, toner and laser safety, ESD prevention, ESD-safe workstation
	* General Information (pp. 8-24): connecting the printer (Peripheral-8, LocalTalk, Centronics parallel), cable connectors (11), printer connectors (12), printer pinouts (13), switch settings (19), troubleshooting tips (20-24)
	* LaserWriter Pro 600/630 (pp. 26-82): exploded views and parts lists for the printer, envelope feeder and sheet feeder (26-34), board and RAM SIMM configuration (35), specifications (36), printer diagnostic (38), test and configuration pages (40), troubleshooting with sensing system, flowchart and 36 tables (42-80), wiring diagram (81)
	* LaserWriter Select 300/310 (pp. 84-138): exploded view (84), parts list (86), I/O boards (89), specifications (90), status LEDs (92), service test page (93), RAM upgrade (96), troubleshooting with separate flowcharts for the 300 and 310 and 30 tables (97-136), wiring diagram (137)
	* Personal LaserWriter 300 (pp. 140-178): exploded view (140), parts list (141), I/O and controller boards (143), specifications (144), status LEDs (146), paper paths (147), sensing system (148), service test page (149), mirror adjustment (151), registration adjustment (154), troubleshooting (156), wiring diagram (177)

	~~== What it settles ==~~
	The parts lists are alphabetical and give Apple part numbers, for example 661-0807 for the Pro 600/630 DC controller board and 661-0029 (120 V) and 661-0028 (240 V) for the Personal LaserWriter 300 controller assembly.<ref name="parts">''LaserWriter Printers, Volume II'', Main Printer Parts List, p. 27, and Personal LaserWriter 300 Parts List, p. 141 (PDF pp. 33, 147).</ref> Apple says to check any part number against the current AppleOrder system, AppleLink or the Apple Service Price Pages before ordering, because the guide is not updated regularly.<ref name="intro" />

	The General Information tab gives pin-by-pin signal tables for each printer's ports. The Pro 600/630 RS-422 port is a mini DIN-8 (1 HSKo, 2 HSKi, 3 TxD−, 4 GND, 5 RxD−, 6 TxD+, 7 GPi, 8 RxD+); its RS-232 port needs only pins 2, 3 and 5. The switch-settings table lists the port and mode (PostScript or HP PCL 4) for each Pro 600/630 switch position.<ref name="pin">''LaserWriter Printers, Volume II'', Printer Pinouts and Switch Settings, pp. 13-19 (PDF pp. 19-25).</ref>

	The Personal LaserWriter 300 section has two adjustments. The mirror must be readjusted after the mirror or the laser/scanner assembly is replaced, using the scale on the mirror assembly and a service test page. Registration must be adjusted whenever the controller assembly is replaced; the optimum leading-edge distance is 2 mm.<ref name="adj">''LaserWriter Printers, Volume II'', Mirror Adjustment and Registration Adjustment, pp. 151-155 (PDF pp. 157-161).</ref>

	The safety section says to unplug the printer before servicing and to leave it switched off for at least 5 minutes before working on the fuser.<ref name="safe">''LaserWriter Printers, Volume II'', Safety, p. 2 (PDF p. 8).</ref>

	~~== What this guide does not contain ==~~
	There are no schematics and no component values. The wiring diagrams show connectors and cable runs between assemblies. The parts lists cover the modules and spares Apple sold for service, not every component.<ref name="toc" />

	~~== Duplicate files ==~~
	The same scan was uploaded twice: [[:File:LaserWriter Printers Service Guide Volume II September 1993.pdf]] has the same SHA-1 checksum and is described at [[Laserwriter Printers Service Guide Volume Ii September 1993]]. A separate 184-page scan of the guide is at [[Apple Service Guide Laserwriter Printers Volume Ii Sept 1993~~]].~~
