You can calibrate the printer in the basic configuration of the app (e.g. productionAssist or materialAssist) and print test labels. If this is not possible, make sure that the power cable is plugged in and that the main switch on the printer is turned on. Please also check whether the printer is connected to the by a USB cable.
Please use the included USB cable. If the supplied USB cable is too short, please use a USB cable with signal amplifier in the required total length instead. A simple USB extension cable should not be used, as the signal strength may be too weak and the printer will not process the print jobs or only partially.
If there are still problems, follow the link to the diagnosis.
Tip:
It often helps if you disconnect the HOMAG CUBE and the printer from the power supply and switch on the printer first and then the HOMAG CUBE.
