If ST-4050 heat press machine can't bounce automatically,it may not bounce automatically because the spring push rod has no elastic force and the air pressure in the spring push rod is insufficient.It is also possible that the pressure is not adjusted properly,and the pressure will not be able to bounce automatically if the pressure is not adjusted properly.If there is a problem of open the sublimation machine can operate but cannot heating,first check the heating sheet.The heating plate of flat heat press machine is burnt.Then heat fuse does not reset.If ST-4050 plug in but no power,it may be because Excessive current causes the fuse burnt.Also consider that the circuit board is burnt. There is also a short circuit inside the machine caused no power.
If you want to ask ST-4050 heat transfer machine how to adjust the pressure,just debugging through the adjustment scress and rotary knob,do not adjust too much pressure,press down lightly,it will be ok when time reach bounce automatically.
