4 Never use any sharp tools for removing stuck labels. The
printhead and rollers are delicate.
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 isopropyl alcohol. Do not use any
other type of chemical. Be careful not to scratch the guides.
Some Intermec RFID option kits use the media guide to house
the RFID antenna. Be extra careful not to damage the antenna
when following the procedure described below.
Isopropyl alcohol [(CH
