There are five interrelated adjustments for obtaining optimum print quality and increased 
printhead life:

•

printhead parallelism

•

printhead balance

•

printhead position

•

printhead pressure

•

strip plate position

The illustrations and adjustment procedures reference a right-hand print engine. Left-hand 
print engine positions and rotations are in the opposite direction.

To achieve optimum results with print quality adjustments, install full-width media and ribbon.

Excessive toggle pressure leads to increased printhead wear and decreased 

printhead life. Increase printhead life by combining minimum toggle pressure and optimum 
printhead position over the platen roller.

Verify the media and ribbon are properly matched and darkness/print speed 

configurations are correct for the application before performing any mechanical adjustments.
