The Busy signal is active (HIGH) under the following conditions:
- During data reception (See Figure 1-7.)
- When the input buffer is full
- When the INIT input signal is active
- During initialization
- When the ERROR or PE signal is active

- When a fatal error occurs
The PE signal is active (HIGH) under the following conditions:
- When a paper-out error occurs
- When a fatal error occurs
