    No action necessary.

    Press the feed button to resume printing.

    Load a roll of labels and follow the instructions in Loading the Paper then press the feed button to resume printing.

Make sure you have installed the proper Ribbon:

  • B483 labels : R-6002 White Plastic Core
  • B478 labels : R-6002 White Plastic Core
  • B427 labels : R-7950 Black Plastic Core (Cable labels only)

Is the label or ribbon loaded correctly? Follow the instructions on the quick start guide in loading the paper or loading the ribbon.

Make sure the labels are loaded accurately.

Make sure you have selected the right label format in the ASML portal.

Make sure the printer is installed properly on the computer AND in the portal (see Quick Start Guide). Try to do a testprint from the Windows driver, if the printer responds it is installed properly and you need to check the settings in the portal.

Sometimes the portal can’t see the first installed printer on a computer. Adding the printer again in Windows will fix the problem. Another solution is to delete the printer you just installed, add a “dummy” printer (Generic Text driver for example) and then add your TTP-343 printer.

Make sure you have the latest version of Java and “add” ASML as a Trusted site. You will need admin rights to perform this action. Go to to download the latest version of Java.

Follow the instructions on the instruction sheet in the download section.

Make sure you install the labels with the printable area facing up and the “notch” on the righ-hand side.
