4. Adjustment Knob 
 
There are two conditions that will need to adjust the print head pressure. 
 
1.  Print with thick media 
If media thickness is larger than 0.19 mm, the larger pressure is required to get good quality 
printout. 
2.  Edge alignment media 
The media alignment is designed at the left edge of mechanism to keep the pressure 
balance between print head, media and ribbon. 
 
There are 5 levels of pressure for adjustment. Level 1 is the minimum pressure and level 5 is the 
maximum pressure. 
For example, if the label width is 6”, adjust both print head pressure adjustment knobs to the same 
level. If the label is less than 2” wide, 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. If the left side print head adjustment knob setting has been set to 5 (the 
highest pressure index) than increase the middle print head pressure.  
Please refer to the following pressure knob adjustment recommendation.
