6. Label Slack Absorber
6.1 Description
The label slack absorber compensates for sudden jerks at the paper
web, e.g. when high speed printing is started and stopped. When the
printing starts, the tension is increased and the absorber is pulled
forward/upward. Soon the heavy paper roll starts to rotate and the
tension decreases. The spring-loaded absorber can then return
towards its original position. During the printing, the absorber will
flutter back and forth, compensating for the variations in tension.
To facilitate paper load, the label slack absorber can be rotated 180
°
clockwise. It cannot be locked in open position.
For demanding applications with high speed printing, a guide can
be fitted on the label slack absorber to prevent paper misalignment.
The guide is included at delivery of the printer, but is not fitted as
standard.
