The LX900 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
