LaserJet 4 won't Power Up
I have a this wonderful LaserJet 4 which will power up (sometimes). Other times switching it on does nothing. I just turned it on and the indicator lights lit up without lighting up the display, it began to warm up, then completely shut down. Any hints?? If I need to replace the power supply, do you have one of these for this old jem available?? Thanks!! SaTerraji
I haven't seen that particular behavior on that model. It either works or it doesn't. My first choice would be the power supply.
I was wondering if you have found a resolution to your problem. I am having the same problem with my LJ4. Sometimes it begins to start, other times it does not. But it never gets past the startup.
