When a copier or printer won't turn on, it's often because of a blown fuse, tripped breaker, or bad power supply (assuming you've ruled out the power coming from the wall outlet). If it's after a power outage or surge, it's likely something in the internal power supply that's causing the problem. If the power supply board has a fuse or breaker, you may just be able to replace the fuse or reset the breaker, but otherwise you may need to replace the power supply.

If it's not the power supply, it could be an internal component that shorted out (like something in the fusing/fixing unit) but this can be extremely difficult to troubleshoot.
