34 Troubleshooting and Maintenance
The LX2000 decides where to start printing by detecting the start of the 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). 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" through the backing/liner to detect the
edges of the labels. If it can not adequately "see" through the backing/liner, 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.
3. Insufficient Label Gap Distance. See Section 2A for label specifications.
4. Page Size is Bigger than Label Stock Size. If the page size set in the driver is larger
than the actual label stock, ink will be printed on the gaps and the sensor will start
looking for a gap too late. This can cause label skipping or inconsistent print starting
points.
5. Portrait/Landscape. If the Portrait/Landscape setting does not correspond to the label
stock installed this will also cause the printer to print over the gap and onto the next
label. Make sure this is set correctly.
6. Stock Sensor Position. Circular, nonstandard label shapes or multiple labels across will
require precise adjustment of the label sensor. If you are using circular or other non
rectangular die-cut labels see Section 2C for instructions.
Three things can affect this issue.
Label Stock Loading. It is very important to correctly load the label stock so that there is
no space between the throat guides and the label liner edge. If there is a gap between the
throat guides and the label stock it may "walk" back and forth causing inconsistent
horizontal image location. See section 2B for label stock loading instructions and tips.
