Wrinkling
An example of wrinkling is shown in Appendix B "Color Test Patterns."
Wrinkling occurs when the transfer roll is not maintaining smooth, even contact
between the thermal head and the paper; instead, it is wrinkling and rippling.
1.
Clean the thermal head. Refer to the Chapter 7 topic "Cleaning." If
necessary, use the service cleaning kit (order number 016-1058-02) to
"deep clean" the thermal head.
2.
Determine if the transfer roll has been unrolled and then rolled up
again. Uneven packing in the transfer roll causes uneven tension that
results in wrinkling.
3.
Inspect the thermal head for damage. If it is damaged, replace it.
Refer to the Chapter 8 topic "Thermal head" on page 8-18.
