Got the same, or almost the same problem. In my case after I reseat 4 chips (what are they?) in different order, I was getting all 4 solid lights. Except, best I got to now, when reseated them in original order, I am getting solid green, solid paper out, and flashing paper jam. Got a feeling, it might be one of those chips. Wonder if they are to be get somewhere. Also IIg board has a slot for testing the board. anyone knows what tester is needed? I had to put in IINT board, which wouldn't be that huge problem, if I didn't have to get each time I need to print out of OS X to 9.2.2, because OS X will not even see IINT. Just need that ethernet port. BTW, anyone knows where can be seen schematic of the IIg board? It's not in a manual. Pilgrim
