In the less than 10 months since I've had my NeXT, I've had the printer fuse blow *seven* times. I can replace the fuse, but this is getting to be a real hassle. So... 1. Have any other NeXT folk experienced similar problems? 2. I could modify the rc script to refrain from starting the np daemon. Likewise, I could put a wrapper around /etc/shutdown to do an "nppower off". Do you think either of these would help? 3. I'm not sure whether the fuse blows upon power on or power off. Aside from the above two kludges, can you think of a good way to tell? 4. Any other thoughts or suggestions? /dave -- Dave Paulson dpaulso@relay.nswc.navy.mil (work) Synetics/NAVSWC talos!SandBox!dave@uunet.uu.net (home,NeXTmail)

Fuses usually blow from power-surges, i.e., when starting up a device and its impedance is low; I would contact NeXT to check if your printer is not drawing TOO much current (leaky capcitor, or some jammed mecahnical part which slows down the motor, or what have you; I was an electrical engineer 40 years ago ...).

Do you have dirty power lines in your area? If so, you might want to put a line conditioner or filter..... - jiro nakamura jiro@shaman.com -- Jiro Nakamura jiro@shaman.com Shaman Consulting +1 607 277-1440 Voice/Fax/Data "Bring your dead, dying shamans here!"

Try going to your nearest NeXT service facilty. I once had a NeXT printer that dis the same thing. NeXT had me replace the DC power supply. I was told that some of the original powers supplies are susceptible to power surges.

I called NeXT and they had Motorola replace the power supply on-site. The service manager at NeXT said that old power supplies were sensitive to unreliable power sources and the new power supplies were 10x more robust. BTW: I was _extremely_ pleased with NeXT's response to my problem after feeling 'stuck' by Businessland. Also, a colleague (w/ no backup) had disk problems and a local NeXT support rep. came out and personally reloaded the OS onto the sick machine. I have gotten consistently the best support from NeXT compared to the many computer hardware vendors I have dealt with in the past 12 years.
