Here is the text in case the link drops:
Question Why can't I cut the tape after printing a label?
Answer Every time a label is cut, residue from the label's adhesive remains on the cutter blade. This is a normal occurrence when the LabelMaker is used frequently. It is important to regularly clean the cutter blade in the cassette compartment with either the special brush delivered together with the LabelMaker (located in tape compartment door) or a cotton tip swab and a soft solvent (e.g. alcohol).
If the solution above does not resolve the problem, check for tape path obstructions. If the problem persists, please contact DYMO Technical Support to obtain a Return Material Authorization (RMA) number.
