Chapter 6 — Label Slack Absorber

6.1 Description

46
The label slack absorber compensates for sudden jerks at the media, for
example when high speed printing is started and stopped. When the
printing starts, the tension is increased and the absorber is pulled forward/
upward. As soon the heavy media roll starts to rotate, the tension decreases.
The spring-loaded absorber can then return towards its original position.
During the printing, the absorber will fl utter back and forth, compensating
for the variations in tension.
To facilitate media load, the label slack absorber can be rotated 180° clock-
wise. It can be locked in open position using a snap-lock. Remember to
unlock the slack absorber before starting to print.
An adjustable edge guide is fi tted on the label slack absorber to prevent
media misalignment. The guide is fi tted as standard, but can be removed
to facilitate media load when there are other means of guiding the media,
for example a media roll retainer or fan-fold guides (see Chapter 5).
