•

Check for wrinkles on the carbon ribbon.

•

Make sure the print head is clean.

•

Unreadable barcodes can also occur if the barcode size is too 
big or too small. Confirm that they are within barcode specifica-
tions.

•

Confirm that the scanner is set up to read the barcode type 
printed.

•

Make sure you are printing a standard barcode symbology and 
that the characters you are trying to encode are legitimate.

•

Make sure that the label media and the carbon ribbon are com-
patible. Resin-based ribbons are not always compatible to rough 
low quality labels and wax- based ribbons do not always adhere 
well to some synthetic label material.

It is possible that you have the wrong label sensing method 
switched on for the media you are using. Check the DIP switches 
against the DIP switch function guide on the inside of the top cover 
to see if you have selected the appropriate method for you paper. 

If you are using the label gap method, check that the gap between 
the labels is more than 3mm, or if using the I-mark method, that the 
I-mark is bold and also more than 3mm. Finally, confirm that the 
label is passing over the sensor. 

Is the power LED illuminated? If not, check the power switch is on 
and confirm the power supply and connections. Also confirm that 
the print head has been closed properly.

The printer is trying to receive incorrect data. Make sure you are 
sending data in the correct format.

Confirm that the sensing method selected matches that of the 
media used and that the media has been routed under the sensor.
