Z-Axis Adjustment Escape Sequence
Introduction
The Model 8900 Series Printers sense top, left, and right edges plus
thickness when a form is loaded. These settings provide the location
of printout on the form such as top, bottom, left, and right margins
and locations of labels or uneven edges.
Caution: Some forms or form sets may have isolated stick-on
labels or some areas that contain more copies than others as
illustrated in the following figure. These conditions, if not
properly handled, can cause the printhead pins to snag on the
uneven edges and result in damage to your printhead. To prevent
this type of damage, avoid any situation in which the printhead
prints across an uneven edge.
If your applications require the use of the types of forms shown in
the following figure, you should use Z-axis adjustment escape
sequences to handle them.
Note: The 8900 Series Printers make Z-axis adjustments automatically
only when forms are initially loaded, power is cycled, or the power-on
defaults are reset.
