7. INPUT BUFFER BACK-UP FUNCTION

7.1 Input Buffer Back-up

If the power is turned off, or there is a power failure during printing, the data in the input buffer will be retained. When the power comes back on, the power failure symbol (..... PD) will be printed in red, and then the data which

was interrupted will be printed from the beginning of the line where the interruption occurred.

Note: The input buffer back-up function may not operate properly if the related capacitor is not sufficiently charged. This may be the case if the printer has not been operated for a long period of time. After the printer power switch has been turned on for 10 minutes, the buffer back-up should be effective for approximately 100 hours or more.

7.2 Clearing the Input Buffer

In case it is desired to delete the data in the input buffer, the power switch should be turned on while pressing the LINE switch. When deletion of the buffer is completed the buzzer will sound. Please be sure to continue pressing the LINE switch until that time.

If the printer fails to work properly at the time the power switch turned on, please delete the input buffer as described above before inputting new data.
