LaserWriter 4/600 PS PRINTING PROBLEMS

Auto Check:

There is a lever underneath. It is slightly toward the center from the position of the status lights, in a slot that runs from front to back. Pressing it will cause the "marking engine" to print a full page of Vertical lines, about 6 lines/inch. The controller, which handles PostScript, communication, etc. is bypassed for this test. Problems with this test are in the "printing" portion, not in the "imaging/communication" portion of the printer.

More Test Pages:

If you have a Mac that can run Classic, Apple Printer Utility runs under Classic and can print test pages, font samples, and allow you to set printing options. It is available for download from the older Software Downloads page.

Are you using North American English System? If you cannot find it in your language, post your System Language and someone can help you find the download.

Mac OS X support:

This is a Postscript level 2 Printer, and is supported by Mac OS X Printer Drivers. It is an AppleTalk/LocalTalk printer, and mac OS X does not directly support LocalTalk. To print under Mac OS X requires a Protocol Converter that can translate AppleTalk-over-Ethernet to AppleTalk/LocalTalk.

The service manual has this to say for "All Black page":

1) Replace the controller assembly with a known-good controller assembly.

Does the problem persist?

-No -- Problem solved.

-Yes -- Replace the laser/scanner assembly.
