4.2 Print Head Burn Line Adjustment Knob
The print head burn line adjustment knobs are used to fine tune the print quality for different thickness
of media. Turning the knobs adjusts the print head’s burn line forward or backward as it relates to the
platen roller.
The print head burn line default is set for general purpose printing media (plain paper and paper
thickness less than 0.20mm). In general using, it does not need to adjust the print head burn line. If you
have poor print quality, please modify the printer density or adjust the print head pressure adjustment
knob, or adjust z-axis mechanism first.
Caution:
Incorrectly adjusting print head burn line adjustment knobs can lead to poor print quality and
may cause damage to the printer. Proceed with caution.
Poor print quality when using paper thicker than 0.20mm may be due to the print head burn line not
being at the optimized position. To improve the print quality, increase the head pressure or adjust the
knobs counter-clockwise to move print head burn line toward the paper out direction then print again.
Continue to adjust the burn line position and test print as necessary until the printout image is clear.
