1.Switch off the printer.
2.Press the print button, but do not release it.
3.Switch on the printer without releasing the print button.
4.Release the print button when the printer starts printing.
The printer starts by printing information as in test method 1. It then stops and will continue printing once the data is sent to the printer. By checking the received data, you can determine whether character received agree with the Label point- commands and the transferred ASCII- characters.
Differences between the received signals and the transferred characters may be due to incorrect parameters (e.g. Baud rate) or the presence of electrical inference during the transfer. Check the communication cable, the length of the cable and whether or not the cable is close to power cables.
Cancelling Test Methods
To cancel the test methods, turn the printer off and wait 15 seconds before switching it on again.
