I know it's an old machine- The quick fix/test would be to replace the fuser but- a fuser is about $500.00.
I think the machine is worth that much when new!
I tested the fuser lamp- okay-- tested the thermistors and there resistance matches cool and warm (by pressing finger to see change) and they seem okay-slight wear though.
I wasn't sure of the power supply board-- but-- I came to the machine and the display only showed an up arrow- nothing else- like it was in sleep mode pressing buttons unplugging and plugging in machine wouldn't get it going. I took the heater out and tested it, took about an hour- then put it in and machine got ready- then got error E000 so I reset and machine is ready.
I told customer to shut main switch when not using machine so it wouldn't go into sleep mode-
Now????
Is it the Power Supply or The Fuser??? (Wasn't sure how to test fuser will check in manual-but what if it's erratic.)
