My DL4 prints one good label
and then the red error light comes on.
The most likely cause of the problem is that
one or both of the two black plastic spindles
that hold the ribbon cores are installed backwards.
The large end or flange of each plastic spindle
should be on the right side as you face the machine
from the front.
There is another possibility when printing
die cut labels. When printing die cut labels
be sure the driver settings are as described
in the Help information included with the software:
Sensor Type: vertical
Gap / Black Mark: 0.12 inch
Options: select "cut every" and enter
"1" in the box.
Options: Offset: adjust with trial and error
depending on which size and type of die cut
label it is (a negative number moves cut to
the right, positive to the
left)
All other settings should be zero.
If the settings in the driver are correct try
rebooting the computer.
