A. SOLVING PRINT ALIGNMENT PROBLEMS
Image is Vertically Offset
The LX900e decides where to start printing by detecting the start of
die-cut label, detecting a black mark on the back or detecting a thru-
hole that corresponds to the start of the label.
The following items can cause the label sensor to improperly detect
the start of a label:
1. Top of Form (TOF). TOF stands for Top of Form and this setting
allows you to fine tune the alignment of your
printing on your label stock. This will be factory
calibrated. If fine tuning is needed, increase this setting to move
the image down on the label; decrease this setting to move the
image up on the label. The unit of measure is 0.1mm. This
setting is found on the Alignment Tab of the PTStatus Monitor.
2. Nonstandard / Non-translucent Backing Material. Test the unit
with the label sample material that came with the unit. If it
prints correctly, your label stock may not be
compatible. The label sensor needs to see the difference between
a label and a backing material by seeing through the label stock
for light variations. If it can not see through the label, problems
will arise. If you must use this type of backing, try label stock
that has a black mark on the back to show where the label
begins. You will need to change the Stock Sensor Mode in the
Status Monitor.
