Clean the thermal head,

especially the brown part at

the center. (Use the cleaning

cloth or alcohol.)

When the positions of pay-off side

and take-up side of the ribbon are

not in a straight line, the ribbon is

creased and, as a result, a blur

occurs in a slanting direction.

Install the ribbon straightly (set

the both sides of the ribbon at the

center) and align the position of

the ribbon so as not to make a

wrinkle.

When no signs of improvement are shown,replace the thermal head with a new one. The thermal head may have reached the endof its operational life.

Ink Ribbon Comes Out Stuck to the Label!!

Clean the thermal head and print labels with the

print density set to 0. See “1. How to Adjust

the Density”.

Check 1

One of the most common causes of this problem is that the ink ribbon is

fused into the thermal head because of a larger supply of energy than

necessary to the thermal head.

If you do not have a spare thermal head and want

to continue printing labels even if the print

quality is deteriorated, follow the procedure

below. Head error is temporarily ignored. (Be

aware that the broken wiring in the thermal
