6. The Platen is the rubber roller directly below the Print Head. It should be cleaned

of any ribbon or label residue.

7. A pair of Label Feed Rollers are used to assist in label feeding at high print

speeds. One located in the bottom of the Label Hold-Down and the other directly

underneath it in the label feed path. They should be cleaned of any label residue

or foreign material.

8. Repeat if necessary. The platen and rollers should be cleaned whenever foreign

matter such as dust or adhesive is present.

9. Close the Label Hold-Down until it latches in place.

10. Close the Print Head by rotating the Head Latch Lever down and towards the

front until it latches in place.

CLEANING THE LABEL EDGE 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 backing paper which is translucent and detecting the presence of the opaque

backing. 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.
