I had a type 2, so things may be slightly different
The lamp knob on the Zone VI TIMER should be set at max. There should be a separate controller for the blue and green lights, and on this controller is a switch to turn both lights at max for focus. Also on this controller is a knob to set light intensity
I set it at about 90 to 95 percent. For normal printing, set both green and blue to max, and still, the times are a bit long. To change contrast, reduce one light and leave the other at max. Its a great enlarger, and you will soon see how good it works. Good luck!
