Your printer comes with one label cassette. Visit www.dymo.com for information about purchasing 
additional label cassettes.
To insert the label cassette
1Press and release the label cassette cover to open the label compartment. 
See Figure 3.
NOTE The first time you use the printer, remove the protective cardboard 
insert from the label exit slot. See Figure 4.
2Set the cassette switch for the size of the label cassette that you are 
inserting. See Figure 4. A notch in the cassette fits over the switch when 
the cassette is in the correct position.
3Make sure the label and ribbon are taut across the mouth of 
the cassette and that the label passes between the 
guideposts. If necessary, turn the spool clockwise to tighten 
the ribbon.
4Insert the cassette and press firmly until the cassette clicks 
into place. See Figure 4.
5Close the label cassette cover and press Ato turn on the 
power.
You are now ready to print your first label. For complete details 
on how to use the label printer refer to the LabelPoint 350 User 
Guide.
