5.4 THERMAL HEAD CLEANING
If ink, glue, or other foreign matter adheres to the print surface of the thermal head, head conductivity will be
diminished, resulting in poor print quality.
(1) Wipe the surface of the head clean using a soft cloth moistened with a specialized head cleaning
formula.
CAUTION!
•
Do not touch the surface of the head with hands or metallic objects.
•
Never use thinner to clean the head as it may damage other parts of the scale.
5.5 OTHER ADJUSTMENTS
Four limit bolts in the platter base function to prevent damage to the load cell from weight overload.
Four-corner adjustment is performed when the load cell is replaced or when external impact to the scale
necessitates it.
1. Four-corner adjustment
Place a weight equal to scale capacity (15kg/
30lb) plus 10% (1.5kg/3lb) on each corner of the
weigh platter base in rotation.
Rotate each of the four-corner adjustment screws
so that they just make contact with the limit bolts
when the weight is loaded [Gap (a) in diagram].
