3d Sublimation Vacuum Heat Press Knowledge

If  ST-420 3d sublimation vacuum heat press couldn't pump air full.You need to check the main problem is the air fitting leakage of this heat press machine.Need to check the  bottom four-way connection,the throttle valve on the solenoid valve, and the connector on the air filter.If ST-420 3d sublimation vacuum heat press couldn't automatic lifting,you need to check the air fitting leakage caused the upper heating plate couldn't up and down.And check the button problem caused the upper heating plate couldn't down when push the down heating plate in of the 3d sublimation vacuum heat press.The display automatic button failure.If ST-420 3d sublimation vacuum heat press couldn't vacuumize,maybe the silicon breaks(Maybe pierced when transfer the goods) ,and check whether the air pipe falls off when pulling the down heating plate.Last,the vacuum pump no suction.It is possible that the dirt gets into vacuum pump of this sublimation machine,blocking the suction hole.
