Printhead Lift
Your QLS-4100 X printhead is mounted to a center-pivoting shaft. This permits
even pressure to be applied by the printhead across the width of the media. When
using narrow media, the Printhead Lift Screw allows you to relieve unnecessary
pressure of the printhead against the platen roller. This will prolong the life of the
printhead and platen while providing a more even application of downward pres-
sure onto the media where it is needed.
Tools Needed
Slip Joint Pliers
Using a pair of slip-joint pliers grip the Printhead Lift Screw
• Turn the screw clockwise to lift the head and relieve pressure
• Turn the screw counterclockwise to lower the head and apply pressure
This adjustment is best performed while the printer is printing so that you can
evaluate print quality as adjustments are made.
