4. Moveable Print Head Pressure Adjustment Knob
The moveable print head pressure adjustment knob has 5 levels of adjustment. Because the print engine’s paper
alignment is to the left side (or right side/ PEX-1200 series) of mechanism, different media widths require different
pressure to print correctly. Therefore it may require to adjust the pressure knob to get your best print quality. For
example, if the label width is 4”, adjust both print head pressure adjustment knobs to the same level. If the label is
less than 2” wide with PEX-1100 series, increase the left side print head pressure by rotating the adjustment knob
clockwise and decrease the right side pressure by rotating the adjustment knob counter-clockwise to level 1.
