Workcentre pro 416 S instructions didnt come with new drum replace drum message stays on and it wont allow us to do anything no buttons will work it's in "lockdown" Help?

On this 416 copier, the machine has a side door, with a plunger on it. Most times the operators close the door using one hand. When this happens the door bends and causes the plunger not to fit correctly when the door is closed and breaks the plunger mounts. If one can reinstall the plunger successfully, the new drum unit should work. This is because the plunger is pushing in the mechanical components on the drum unit when the door is closed; satisfying conditions the door is properly closed.

These levers are for safety reasons, to protect the expensive drum unit, safety for the operator, opening and closing of the right door, and the operation of the copier.

For one to remove the cover from the drum, one would need to understand what they are doing before removing the cover. It can be done, but it is not recommended.If the machine stays and says enter new drum, the drum unit may not be good.

In the end, best to place a service calls and let the service representative service the machine.

YOu can go online and type in the make and model and they should be able to download the instructions for you
