What to do if nothing appears on the display of Casio KL-7400 Label Maker?

If nothing appears on the display of your Casio Label Maker when you press the power button, there are a few potential causes. The display contrast setting may need adjustment. Ensure the AC adapter is properly connected. Low battery power or using the wrong type of AC adapter or batteries could also be the problem, so try the correct AC adapter or a fresh set of AA-size alkaline batteries. Also, make sure that the batteries are loaded properly. In some cases, the print head may be overheating; if this is the case, wait a while and try again.
