Print density
Selectable from 70 to 130% (in 5% increments)
Initial setting: 115%
To ensure good print quality, it is recommended to set the print density according to the paper to be used.
("Recommended Print Density for Certified Base Paper" on page 125)
• The higher the print density is set, the more likely the print speed will decrease.
• The higher the print density is set, the more likely it is that paper dust will adhere to the surface of
the print head, resulting in blurred printing.
Print speed
Selectable from levels 1 to 11 (Slow ~ Fast)
Initial setting: level 11
Depending on the printing conditions, such as print duty, head temperature, and data transfer speed,
the print speed may be adjusted automatically and may cause white streaks on printouts due to
intermittent printing (the motor stops occasionally during printing). To prevent this, set the print
speed to a lower speed.
