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.
Caution: Incorrectly adjusting these knobs can lead to poor print quality and
may cause damage to the printer. Proceed with caution. Do not adjust unless
you have first consulted with tech support.
The print head burn line default is set for general purpose printing media (plain paper
and paper thickness less than 0.20mm).
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.
