Hi, how are you? If you mean that the printer does not pull the opaline sheet, you will have to clean the pick up of the same (rubber that pulls the sheet), you can do it with a clean cloth and some isopropyl alcohol , if you continue like this you will have to help a little, when you start to carry out the printing process, push the opaline sheet into the printer, when you pull it, you can print it and you will be able to print .... Also check the type of paper what do you set up to print .... Luck ...
