The media roll adapters kit includes three pairs of media roll adapters. The kits are for the following inner diameter (I.D.) media cores:
38.1 mm (1.5 in.)
50.8 mm (2.0 in.)
76.2 mm (3.0 in.)
The adapters are intended to be permanently installed in the printer. You can replace them as needed to support other media roll sizes that require one of these adapter sizes.
The adapters may wear out if they are changed too often.
When you remove the media adapters to print on standard roll cores, the plastic pieces on the sides of the media roll holders may rub against the roll. If this is the case, push the attached pieces back into the side of the media roll holder.
