Table 12. Printer Problems and Solutions
Prints strange characters
instead of the correct label
format.
1.
If the printer serial interface is being used, check that the
printer serial baud rate setting matches the baud rate of
the host computer. Reset the printer via software, or turn
the printer off and then on.
2.
Check if the printer serial host interface is set for 8 data
bits but the transmitting device is set for 7 data bits (or
vice-versa). Check the current setting by viewing it on the
LCD, and use the Host IO > Serial section to adjust the
settings, if necessary.
3.
If the printer parallel interface is being used, make sure the
parallel interface terminating resistors are correct for the
host computer drivers.
• Start of image is printed
an erroneous distance
from the top-of-form.
• The printer starts to print
one label and then
another, all within the
same physical label.
1. Make sure the Media > Image > Label Length value
matches the actual
physical length of the label installed
and the run on Auto
Calibrate (see Running Auto Calibrate
page 38).
These symptoms could be caused by:
• Severely curled labels near the end of a media roll
• Media sensor triggering off of a dark, preprinted image
on the label
• Multiple gaps within the physical label.
2.
Set Media Image > Clip Page to Disable.
3.
Run a Media Profile (see Running Media Profile page 39).
4.
If the Media Profile printout shows that preprinted images
has an amplitude approaching the
Gap/Mark Threshold
level, position the lower media
sensor to avoid the image
or increase the Threshold
Range percent value in the
Sensors > Calibrate section. Run
Auto Calibrate again and
Media Profile to verify there is an
improvement.
• Loss of one or more
serialized labels within a
print job.
• Start of image is printed
in the middle of the gap.
• The top part of the image
is lost when printing with
Head First orientation
selected.
1.
Go to the Sensors > Calibrate section.
2.
Set Gap Windowing to
Enable.
3.
Set Gap Length to equal the physical gap length of the
media installed. The range is 0.05 to 1.00 inches.
The likely cause of these symptoms is that Media Image >Clip
Page = Enable
and a cross-perforation, radical fold or flaw in
the liner has
caused the media sensor to detect this as the
leading edge
(TOF) of the new label or end of label (EOF), or
both.
