Cleaning the Media Guides

Both parts of the label stop sensor, which controls the media feed, are
covered by plastic guides. The guides are transparent to allow the light to
pass between the two parts of the label stop sensor. These areas must be
kept clean from dust, stuck labels, and adhesive residue.
If the printer starts to feed our labels in an unexpected way, pull out the
upper guide as described below and check for any object that may block
the beam of light (dust, stuck labels, adhesive residue, etc.). If necessary,
clean the guides using a cleaning card or a soft cloth soaked with iso-
propyl alcohol. Do not use any other type of chemical. Be careful not to
scratch the guides.
