Currently I have a problem with the Luscher Xpose 120/180. After starting to expose plate I'm receiving error message "laser 18 on sensor too weak". Our ctp has 4 modules, one module holds 8 diodes. I have triede to leave one module to work, but the message allways shows that first laser diode is too weak. And no matter witch module you leave to work the error message will display that laser too weak. It cannot be that all diods is dead. I think that the main laser did not receive information from diods. So where the problem could hide?
