Copier Having a CRT Display

When a document feeder jam occurs, a cathode ray tube (CRT) message instructs the human operator how to clear the jam, and the order in which the manual jam clearing steps must be performed by the operator. The CRT message is updated to indicate the completion of the steps, as they occur.

The copier's document feeder includes a number of paper sensors. When a jam occurs, the state of these sensors is copied into a memory location, and a flag is set to prevent changing these memory locations except under certain conditions.

As the operator moves through the sequence of jam clearing steps, movement of certain of the document feeder's mechanical components is sensed, a flag is then reset, and the CRT message is updated. This is fed back to the operator indicating that a manual intervention step has been completed.

Once all steps have been completed, and in the required order, all flags are reset, and the CRT message is removed.
