Some questions about vacuum sublimation heat press machine

First,if ST-3042 plug in but no power,maybe the circuit board is burnt. Or you can check a short circuit inside the machine caused no power.Second,if you find the ST3042 3d sublimation vacuum heat press machine couldn't full vacuumize when transfer phone case.There may be several reasons.The silicon plate breaks(Maybe pierced when transfer the goods) of 3d vacuum sublimation machine.Or the solenoid valve is burnt. The solenoid valve overheated for long time work of 3d sublimation heat press.The vacuum pump no suction. It is possible that the dirt gets into vacuum pump, blocking the suction hole of heat press machine.Third,if you find ST-3042 sublimation machine transfer effect is not good.Maybe the heating plate of this sublimation heat press is not heating or only one heating plate is heating.Or the time is not enough,or didn't set the parameter as our suggestion.The Temperature not reach. For example:the temperature is up to 180-190degree,and down to 160 degree, then begin to go up.
