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 (indicated by a shade of gray in illustration #2 below) must be kept clean from dust, stuck labels, and adhesive residue.

If the printer starts to feed out labels in an unexpected way, raise 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.

Isopropyl alcohol [(CH3)2CHOH; CAS 67-63-0] is a highly flammable, moderately toxic, and mildly irritating sub- stance.

Lift the inner part of the upper guide and pull it outwards, disengaging it from the lower guide. Take care not to damage the cable.

Tilt the upper guide upwards and clean the areas marked with gray. After cleaning, re-assemble in reverse order.
