hmm i have a question sir, we have problem after the tube infeed then going to print mark, after print mark, many times the tube become loose and then it will become reject, so is it wrong with the sensor eye mark, or my pressure and length for tube infeed is not enough? because the reject is 25%. And i want to know too for the temperature and pressure for the sealing because many time we got wrinkles in the sealing part, Pls give me advice.
