It was a warm up problem. When the machine is down for an extended period, it takes about 10 minutes for it to warm up properly and the light will go off.

The green tab is a corona wire cleaner. there is a spot for it on the base of the unit when you open the right door.

This device will not impact printing on the copier whether it is installed or not. It serves as a holder.
