Variable Resistor
Approx. 90°
Light Dark
Approx. 90°
4. Print-Density Adjustment
Adjust the print density in accordance with the sensitivity of the paper being used.
Fig. 1-5 Print-Density Adjustment
1. The variable resistor is located to the left of the interface connector on the back side of the printer.
2. Use a phillips screw driver to rotate the variable resistor to adjust the print density. The variable resistor will
rotate approximately 180°.
If you are not getting a good print on the thermal paper with the density set to its maximum at 2 Inch/sec print
speed, set the print speed to 1 Inch sec.
CAUTION
Avoid setting density too high for sensitive paper types. Excessive dark values may cause the paper
to swell which will degrade the quality of the image.
