6.1 Description
6. Label Slack Absorber
The label slack absorber (also called “high speed label controller”)
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.
Soon the heavy media roll starts to rotate and the tension decreases.
The spring-loaded absorber can then return towards its original
position. During high speed printing, the absorber will fl utter back
and forth, compensating for the variations in tension.
Since the label slack absorber only is required at high speed print-
ing (> 100 mm/sec. = 4 inches/sec.), it is has been omitted from the
EasyCoder 501 S model, where it is replaced with a simple shaft
with two green guide washers (see below).
To facilitate media load, the label slack absorber can be rotated
180° clockwise to a locked position. A green edge guide can be slid
sideways to fi t different media widths.
