Capacitor C202: on a fusing failure the DC controller cuts current to the fuser heater and charges C202 on the DC controller board. Leave the power off for about 10 minutes, or discharge C202 manually by jumpering the two wires at its base after removing the rear panel and I/O shield.<ref name="c202">''LaserWriter Pro 600/630'' Service Source, Troubleshooting, Capacitor Discharge, pp. 18-20 (PDF pp. 73-75).</ref> The fuser rollers themselves need at least 5 minutes switched off to cool before servicing.<ref name="safe">''LaserWriter Pro 600/630'' Service Source, Basics, LaserWriter Safety, p. 41 (PDF p. 43).</ref>
* '''I/O board''': Motorola 68030 at 25 MHz.
* '''Speed''': 8 ppm letter or A4; 6 envelopes per minute with the optional envelope feeder; no monthly duty-cycle limit.
* '''Power consumption''': approximately '''0.66 kW at 71 °F (20 °C)'''.
* '''Operating environment''': 50-90.5 °F (10-32.5 °C), 20-80% RH, 570-760 mmHg.

Replace the multipurpose pickup roller and separation pad together; the separation pad is part of the multipurpose tray guide assembly.
* '''Capacitor C202 on the DC controller board''' does the same job as C211 in the LaserWriter II: on a fusing failure the DC controller cuts the heater and charges C202. Leave the printer off for about '''10 minutes''' or discharge C202 manually by jumpering the two wires at its base, after removing the rear panel and I/O shield.
* '''Printer diagnostic''': switch off, jumper '''pins 7 and 9 on the I/O board DB-9 connector''', switch on. LEDs flash for about 15 seconds, then hold the "diagnostic executing" pattern; if no error is found all LEDs light and two pages print. The error patterns cover I/O Board, ROM #1-#4, SIMM #1-#2, Fuser Assembly, Laser/Scanner, Main Motor and Fan. '''If the executing pattern lasts more than three minutes, the error is unknown.'''
* '''Registration adjustment''', which is a real measurement rather than a swap: leading-edge registration is set by paper sensor '''PS602''' and variable resistor '''VR202''' on the DC controller board, and the '''optimum leading-edge registration distance is 2 mm'''. Reset VR202 to 0, print three service test pages, measure the distance from the top of each page to the edge of the printed pattern, average the three, and turn VR202 clockwise if the average is under 2.0 mm and anticlockwise if it is over. This must be done whenever the DC controller board, paper pickup block or laser/scanner is replaced.

The LaserWriter Pro 600/630 volume of Apple's Service Source is a 296-page service manual for the LaserWriter Pro 600 and LaserWriter Pro 630. The PDF's creation date is 26 October 1995.[1] It includes theory-of-operation sections, board locator diagrams with designators, a wiring diagram, a printer self-diagnostic and a measured registration adjustment.

Specifications

LaserWriter Pro 600/630 specifications[2]
Item Value
Engine Canon LBP-B270; single-component microfine toner; semiconductor laser with a rotating six-faced prism scanning mirror
Resolution 600 dpi (the Pro 630 prints at 300 dpi when PhotoGrade is on)
Controller Motorola 68030 at 25 MHz; 8 MB RAM, expandable to 32 MB; 2 MB ROM
Speed 8 pages per minute (letter or A4); 6 envelopes per minute with the optional envelope feeder
Power consumption About 0.66 kW at 71 °F (20 °C)
Operating environment 10-32.5 °C (50-90.5 °F); 20-80% RH; 570-760 mmHg

What it settles

Capacitor C202: on a fusing failure the DC controller cuts current to the fuser heater and charges C202 on the DC controller board. Leave the power off for about 10 minutes, or discharge C202 manually by jumpering the two wires at its base after removing the rear panel and I/O shield.[3] The fuser rollers themselves need at least 5 minutes switched off to cool before servicing.[4]

Printer diagnostic: switch off, jumper pins 7 and 9 on the I/O board DB-9 connector, and switch on. The LEDs flash for about 15 seconds and then hold the "diagnostic executing" pattern for about 2 minutes; if no error is found, all LEDs light and two pages print. Error patterns identify the I/O board, ROMs, SIMMs, fuser assembly, laser/scanner, main motor and fan. If the executing pattern lasts more than 3 minutes, the error is unknown.[5]

Registration: leading-edge registration is set by paper sensor PS602 and variable resistor VR202 on the DC controller board, and the optimum distance is 2 mm. Set VR202 to 0, print three service test pages, measure from the top of each page to the edge of the printed pattern, average the three, and turn VR202 clockwise if the average is under 2.0 mm or anticlockwise if over. Apple requires this whenever the DC controller board, paper pickup block or laser/scanner is replaced.[6]

The board diagrams carry designators: VR202, C201, C202 and TB201 on the DC controller; SW601-SW605 and J601-J605 on the pickup controller; PS701 and PS702 on the pickup sensor board; VR401, J401, J402 and TB401-TB406 on the high-voltage supply.[7]

What this manual does not contain

There is no schematic and there are no component values: the board diagrams are locators and the wiring diagram shows connections between parts. No fuse ratings, supply-rail tolerance table or resistance figures for the fuser heater or thermoprotector are printed.[1]
