made in accordance with ribbon running condition. If you have repositioned the thermal
head, it is highly recommended to adjust the ribbon.
6.1 Ribbon Adjustment
To understand ribbon adjustment better, refer to the following explanation.
Ribbon running condition is directly related to the condition of the following
components:
•
Ribbon supply shaft with friction brake.
Ribbon roll is loaded to this shaft.
The friction brake is provided to eliminate looseness from ribbon.
•
Leading shaft
to change ribbon running direction.
•
Heat lines
of thermal head and platen roller.
•
Bottom front edge of thermal head.
•
Bottom edge and surface of ribbon applicator
to change ribbon running
direction.
•
Ribbon take-up shaft.
Take-up core is set on this shaft in order to wind
waste ribbon. Take-up motor powers this shaft.
From the above ribbon components, the ribbon on the printer can be divided into three
parts as shown in Figure 12:
•
Part A: The part of the ribbon between ribbon supply shaft and leading
shaft.
•
Part B: The part of the ribbon between leading shaft and the front edge of
