3.6 Print Head Offset Adjustments
CAUTION Ensure the print head offset adjustments are
correct for your type of print media (thickness &
width). Incorrect adjustments can cause
premature failure of the print head.
The printer has already been factory-set to the label paper with a width of 112
mm (4.4 in). However, the print head offset adjustments might be necessary
depending on the width of the paper and the paper quality. If the print quality
becomes inferior because of the use of the paper other than the standard,
adjust it according to the following:
1. When the print is unclear or blurred because of poor paper quality:
Adjust the offset of the print head and platen by turning the offset adjust-
screw. The print head offset adjustments are made by changing the
inclination of the print head to the platen. This has already been factory-set,
but the offset may have been changed if the print head was replaced or
disassembled. Also, it may change when using a different type of paper.
In those cases, make adjustments according to the criteria below.
a) Standard or label paper (slick paper, craft paper etc.) and thermal paper
b) Thick paper (tag or other similar paper)
