Durst Multigraph Problem!

[boilerdoc]

My Multigraph keyboard is totally lit up (all the LEDs are on) as is the enlarger (L 1200) and will not go off unless I flip the power supply switch. Nothing in the owner's manual is of any help on how to reset it. Any ideas? This one has me flummoxed....

Hi! It might be that You will recieve no mail from Durst. The best way is to search for Durst Multigraph service manual and search for this trouble. I might have a copy at home, but I am not sure.
