Label Alignment = Auto; Label Alignment = No - Datamax M-Class Operator's Manual

4.6.2 Label Alignment = AUTO

In this mode, the printer automatically calculates the 'ALIGN LENGTH' thus eliminating the need to physically measure
the label. This mode is usually preferred in applications that require frequent media changes to labels of different lengths.
To perform an Auto Alignment, in Normal Mode press and hold the button (about 4 seconds). The printer will feed
FEED
labels to calculate the label length. Following the calculation, the printer will save the measurement and align to the top of
form position. Auto Alignment can result in wasted labels during the measurement process (the longer the label length the
greater the waste).
Auto Alignment with the Present Sensor enabled:
If the printer is equipped with the Present Sensor option and that feature is enabled, while the label length is calculated the
printer will pause and illuminate the light after each movement. The operator must press the button for the
STOP PAUSE
alignment to continue. This allows the operator to remove any labels as required; however, labels should not be forcibly
removed since they may not actually be positioned for removal, but at an interim position required for measurement.

4.6.3 Label Alignment = NO

When Label Alignment is not enabled (i.e., set to NO), printing begins at the current label position without alignment,
assuming the label is at the start of print position. Additionally, if the label length is short, labels between the printhead and
the media sensor may be unused.
