2. Firstly, slide the two black plastic parts of the media holder
assembly together. Ensure correct alignment of the guide with
the bar as it can only be installed in one direction.
3. Slide the roll of media over the media bar. The media guide
must be on the right side of the roll of media (as viewed from
the front of the printer) with the ribbed surface of the media
guide touching the media roll as shown in the illustration.
4. Set the media roll and media holder in to the printer as shown
above. It is advisable to pull a length of media forwards and
through the mechanism ready for later positioning.
5. Move the media roll so it is touching the leftside of the housing.
Then slide the black media guide so it is touching the media on
the right side.
Note: Do not try to hold the media too tightly with these guides as it will
cause the printer to jam during printing.
