A. SOLVING PRINT ALIGNMENT PROBLEMS
Image is Vertically Offset
The RX900 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
