We have seen a multitude of counterfeit cans and lids being supplied to our customers causing fitment issues in the machine. These counterfeit cans do not align correctly to fit our lift puck, some lids also may not align to the chuck.  If you receive new cans or lids that don't line up correctly in the seamer please contact a microcanner employee. We can custom make a new puck to fit the counterfeit cans and we can instruct you on how to modify a chuck for the lids.. We require that you ship your counterfeit cans and lids to us with your company name clearly written on the box. If you have questions about this or have counterfeit cans and lids, you can find our company contacts on the “contact” page above.
