Error Notification
Data handling and error checking are resident in the printer. If an error in transmission occurs, an error is displayed on the printer keypad display. However, no message is sent to the host computer and processing continues until the end of the transmission.
Certain errors may put the printer in offline mode. See the Messages Manual for a list of possible messages.
Data Transmission Errors
The printer displays errors that occur during data transmission. Printer fault errors stop the machine, which will not resume printing until the operator corrects the error condition. All these messages take the system offline.
Incorrect Data Errors
The printer pauses when it receives incorrect data from the host computer. During the pause, it displays a message and beeps. After ten seconds, or when the operator presses E, the printer resumes operation. Normally, the printer loses the data that caused the error.
If the host or the communications line goes down during transmission, the printer displays the message
Waiting for command terminator.
Press F1 to abort download.
If you press ! , the batch or format data that was being sent will be lost and must be retransmitted.
