官方故障排除步驟
[Cause of error] The programmed engraving with the defined character height Q513 results in a longer text than is defined in Q574. [Error correction] Reduce the character height in Q513 so that the programmed engraving is no longer than defined in Q574. Set the value for Q574 higher or to zero in order to make a longer engraving possible. Enter the value 0 in Q513 if you want to scale the engraving to the text length set in Q574. 10/2023 [899]
