A recent posting on Omega enlargers jogged my memory into asking this question about my Omega D5500 with the D5500 color head.

There is a button on the controller that both moves the filters out of the lights path and zeros out the enlarger. After pushing the buttons, the controller is supposed to eventually show zero on each of the three colors. Unfortunately, on two of the light multiplier boxes I have it sounds as if the motors controlling the filters are heaving away but it never zeros out. In addition, the one light multiplier box, for the 4X5, used to be able to zero out but now just whirs around like the others. Anyone experience this problem and know how to fix/adjust it?
