Print Head Pressure Adjustment Knob
Because the printer’s paper alignment is to the left side of mechanism, different media widths require different pressure to print correctly.
If width is 4” adjust both knobs. If width is < 2", increase the left side clockwise and decrease the right side counter-clockwise to 1.
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.
Caution: Incorrectly adjusting these knobs can lead to poor print quality and may cause damage to the printer.
On the WPL612 the screws have recessed hex heads for an Allen wrench or hex driver. On the WPL610 and WPL608, the screws are slotted for a flathead screwdriver.
