Operator Panel Messages

The operator panel messages are divided into four types: Status Screens, Status
Messages, User Error Messages, and Service Messages. The characteristics of each
type is described in this chapter. The messages are displayed in the following priority
order:
1. Status screens (lowest priority)
2. Status messages
3. User Error messages
4. Service messages (highest priority)
The printer prioritizes the operator panel messages within each type, if they occur
simultaneously.
