Cleaning the Rollers and Guides
1. The Label Load Drive is located
underneath the Label Hold-Down.It
should be cleaned of any label residue or
foreign material. The Label Hold Down
Roller is located on the underneath side of
the Label Hold Down. It should also be
cleaned of any residue or foreign material.
2. There are two Label Edge Guides used in
guiding the labels through the printer.
They should be cleaned of any residue or
foreign material.
3. Repeat when necessary. The rollers and
guides should be cleaned whenever foreign matter such as dust or adhesive is
present.
CLEANING THE SENSORS
There are two sensors that are used to control the positioning of the label. One is a
transmissive see-thru sensor that detects the edge of the label by looking through
the liner which is translucent and detecting the presence of the opaque label. The
other is a reflective sensor that detects the light reflected from the bottom of the
label liner. When a printed black Eye-Mark passes through the beam, the light is no
longer reflected back to the sensor detector, indicating to the printer that it should
use this position as the start of a new label. When dust, dirt or other foreign matter
interferes with the light path of either of these sensors, the results is erratic label
positioning. These sensors should be cleaned regularly, at least every two rolls of
labels. They are both located on an adjustable assembly in the throat of the printer
between the Label Hold Down and the Print Head.
1. Turn the printer OFF and remove the power cable.
2. Open the Top Access and Side Access doors.
3. Open the Print Head by pushing the Head Latch toward the rear of the
printer. The Print Head is spring-loaded and will automatically open as soon
as the Head Latch is disengaged. Remove the ribbon.
4. Apply isopropyl alcohol to a cotton swab.
5. Carefully insert the swab between the top and bottom portions of the Sensor
Assembly. The location of the sensors is identified by two marks on the front
of the assembly.
6. Move the swab back and forth to clean any residue from the sensors (see page
20 for location of sensors).
