Media Roll Core Size Adapters

Media Roll Core Size Adapters
The media roll adapters kit includes three (3) pairs of media roll adapters. The kits are for 38.1
mm (1.5 inch), 50.8 mm (2.0 inch), or 76.2 (3.0 inch) inner diameter (I.D.) media cores.
The adapters are intended to be permanently installed in the printer. They may be changed to
support other media roll sizes that require one of these adapter sizes. The adapters may wear
out if they are changed too much.
Removing the media adapters to print on standard roll cores may leave plastic pieces in the
media roll holders side areas that rub against the roll. Push those attached pieces back into the
side of the media roll holder.
Installing Media Roll Adapters
1. Place one screw in the top adapter mounting hole of both of the roll holders. Start turning the
screws clockwise using the Torx wrench until the tip of the screw is just protruding through the
inside of the roll holder. The screws are self-tapping.
2. Place the adapter on the inside of the roll holder. The large side of the adapter is on top. The
smooth side (no ribs) faces the middle of the printer.
3. Align the adapter’s top screw hole to the protruding screw tip and pinch it tightly to the roll holder
body. Tighten the screw until there is no gap between the adapter and roll holder. Do not tighten
beyond this point. Over tightening will strip the thread.
4. Insert a screw in the bottom adapter mounting hole. Pinch the adapter tightly to the roll holder
while tightening the screw. Tighten the screw until there is no gap between the adapter and roll
holder. Do not tighten beyond this point. Over tightening will strip the thread.
5. Repeat step 1-4 for the other adapter and roll holder.
