PRINT HEAD PRESSURE SETTING

Print head pressure affects the pressure applied against the ribbon and label by the print head. Adjusting it can

reduce problems with smudging and ribbon wrinkling.

1. Make sure to latch the print head down and stop printing before the adjustment. Loosen but do not remove

the fixing screw labelled in the figure below. Turn the head pressure adjustment knob up (a) or down (b) to

alter the print head pressure from a value of 1 to 5 (default) to A (for adjusting Head Pressure Balance).

2. Repeat test prints to see the effect of the change in head pressure, and repeat the pressure adjustments as

appropriate. When done, tighten the fixing screw to set the pressure in place.

CAUTION: To prevent possible injuries, be sure to stop printing and lock the print

head down before making adjustments to the print head pressure and balance.
