Printhead Pressure Adjustment
If positioning the toggles properly does not solve a print quality problem, try adjusting the
printhead pressure. Maximize printhead life by using the lowest pressure that produces the
desired print quality.
To adjust printhead pressure, complete these steps:
Before adjusting the printhead pressure, check that the toggles are positioned correctly. See
Toggle Position Adjustment on page 119.
Printhead life and drive system life (belts and bearings) can be maximized by using the lowest
pressure that produces the desired print quality without allowing the ribbon or media to
slip.You may need to adjust the printhead pressure in the following instances:
• if there is noticeable bleed or swelling in the printed image (too much pressure)
• if there are voids (too little pressure)
• if the darkness setting (burn duration) is set properly, but printing is too light (too little
pressure)
• if the ribbon slips (too little pressure)
To adjust printhead pressure, complete these steps:
1. As needed throughout this procedure, refer to the PAU SE Sel f Te st on page 150 to print
test labels.
2. Refer to Print Darkness on page 83 to set the darkness value (burn duration) appropriately
for your media and ribbon.
3. Loosen the locking nut on the toggle assemblies.
