Print-Density Adjustment

Adjust the print density in accordance with the sensitivity of the paper being used. The adjustment procedure is as follows.
Density Adjustment Aperture
1 Remove the interface cover, located the rear side of the printer. The cover fits into place; no screws are used.
2 The density adjustor (variable resistor) is now accessible through the aperture located to the left of the interface
connector.
3 Insert a screwdriver (regular or phillips-head) into the aperture and rotate as necessary. The adjustor has a
rotational range of approximately 180 degrees.

5 Avoid setting density too high for sensitive paper types. Excessive dark values may cause the paper to swell,
degrading the image quality.
6 Some thermal papers may fail to produce a strong image when running at 50mm/sec printing speed, even at
maximum density setting. If you have this problem, reduce the print speed to 25mm/sec.
