shutter motor is defective . only a technician can replace

Replace your polygon mirror motor or complete laser unit if you have one available. Replace this a.s.a.p as it can cause your BICU to pop. If your machine is already dead and you picked the code up on the web browser you need to replace the BICU as well. Do not replace the BICU without replacing the polygon motor. If you do you will pop the BICU again.

That is a "second laser synchronization error". Try this: Hit the yellow button, press numbers 1, then 0, then 7, then hit the orange key. When it goes into SP mode, turn off the copier and unplug it. Wait 15 seconds then plug back in and turn on. If that does not fix it then you need to call a tech to service the machine.
