Printhead Burn Line Adjustment Screws

The print head burn line adjustment screws are used to fine tune the print quality for different thicknesses
of media. Turning the screws 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 , print head burn line adjustment will not be required. If you have poor print
quality, please try changing the print speed, print intensity, print head pressure or z-axis mechanism
adjustment first.
Warning:
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 printed image is clear.

Z-axis Mechanism Adjustment Screw

If the left side print head adjustment knob setting has been set to 5 (the highest pressure index) the
wrinkle/ poor print quality can't be avoid, you can rotate the Z-axis mechanism adjustment screw to adjust.
Please refer to next chapter for more information.
