Cleaning the
Media Guides
Both parts of the label stop sensor, which controls the paper feed,
are covered by transparent plastic guides. The guides have areas,
through which the light between the two parts of the label stop
sensor is transmitted. 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

)

CHOH; CAS 67-63-0] is a highly
fl ammable, moderately toxic, and mildly irritating substance.
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.
