OK - here's a challenge for a sharp printer expert. A LW Pro 630 was connected to a Mac server via ethernet and working fine for years. 1 day it stopped working. When you power the printer ON, the printer goes through the normal self-test and initialization routine, except you never hear the laser scanner motor fire-up (the mechanism motor and fan do work). The printer goes READY as if everything is OK. If you send a print job from the server, the printer data LED blinks (as if receiving data), but nothing is ever printed. No error is displayed on the Server or the Printer. The blinking never stops until turned-off. Nothing is printed. We tried: a new laser scanner, board that drives the scanner, power supply, HV power supply, Apple logic board, fuser assembly and even the toner cartridge. Just to make sure nothing was getting burned-out, the parts were then installed into a working printer and they all work. I even tested all the door interlock switches. This 1 has me stumped! Had to eventually replace the printer with another and this 1 now sits idle, unless someone can shed some light on the problem.
