Chapter 12 Maintenance
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 isopropyl alcohol. Do not use any other chemicals. Be
careful not to scratch the guides.
Warning!
Isopropyl alcohol [(CH

Cleaning the
Media Guides
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 grey. After cleaning, reas-
semble in reverse order.
