6-3. Print Density Adjustment

Since the sensitivity of different types of heat-sensitive paper varies, you can adjust the print density by varying the current supplied to the thermal head.

Variable resistor used to adjust the print density

The print density can be adjusted using the variable resistor inside the hole beside the interface connector on the back of the printer.

1.To adjust the density turn the resistor roughly two times using a small cross- head screwdriver.

2.Turn the resistor to the right (clockwise) for a darker print density or to the left (counterclockwise) for a lighter density.

NOTE: If the density is increased to a higher level than necessary when printing on highly sensitive heat-sensitive paper, the dots may be too large and the print quality may decrease.

Excessively high energy adjustment may reduce head life.

6-4. Sensor Adjustment Mode

Sensor levels are adjusted at the factory. If necessary, you can readjust the levels as described below.
