Indeed - the electrician who installed the RCD renewed our house's ground stake and checked out all the neutral connections he could test. We had to get rid of our old fridge as it kept tripping the RCD. We also ripped out some badly degraded wiring to the pergola lights in the backyard in an effort to track down RCD-tripping problems. These Residual Current Devices can end up causing a lot of expense. :-( > or inside the Laserwriter there is a component or wire which is > touching ground > or frame ..... if you understand that better. Could be - it is just strange that it only happens at 7am-ish in the morning and not when we have the laser on at any other time of the day. > Does the laserwriter collect excess toner ?

That's the weird thing Bob - when the laserprinter is not on, the RCD doesn't trip, but if the laser is left on overnight, the RCD trips at 7am-ish. We did have to change the time the pool pump came on as it would also trip the RCD at 7am-ish in the morning but not if we turned it on later in the day or set it to come on at 4am in the morning. Perhaps it's something to do with the dew point. It's also strange the wireless basestation dies (no connectivity) when we turn the laser on (whether the laser is plugged into our LAN or not). Restarting the basestation gets it working again, so the laser must be sending a spike through the house's power circuit when it turns on. Very irritating. > Well it can be just as simple as that , but maybe not this time ! ??? > > Bob Thanks for the suggestions Bob - here's to a little more detective work or a cheap, well-featured new laser. :-) Ciao! -Mart >> >> Anyway, the Brother HL-5250DN Mono laser printer is looking pretty >> good. >> Does anyone know how well it works under Mac OS X?
