Step-By-Step Instructions On How To Load Ribbon And Media On The Zebra ZT420

Here’s how to load ribbon and media on your Zebra ZT420 step-by-step:

Load Ribbon and Media – Zebra ZT420

  1. Open the printer
    1. Lift the media door on top.
    2. Rotate the printhead lever to open the printhead assembly.
  2. Load the Ribbon (thermal transfer only)
  3. Only do this if you are using thermal transfer labels. Direct-thermal labels do not use ribbon.

    1. Put the ribbon roll on the ribbon supply spindle (back spindle).
    2. Make sure the ribbon unwinds from the bottom toward the printhead.
    3. Pull the ribbon under the printhead.
    4. Wrap the ribbon around the ribbon take-up spindle (front spindle).
    5. Turn the take-up spindle a few times to tighten the ribbon.
    6. Tip: The inked side of the ribbon faces the labels.

  4. Load the Label Media (labels)
    1. Place the label roll on the media supply spindle in the back.
    2. Pull the labels forward.
    3. Guide them:
      • Under the media guides
      • Under the printhead
      • Over the platen roller
    4. Slide the media guides so they lightly touch the edges of the labels.
  5. Close and calibrate
    1. Push the printhead lever down to lock.
    2. Close the media door.
    3. Press FEED on the printer.
    4. The printer may feed a few labels to calibrate the sensors automatically.

Important tips

  • Ribbon should be wider than the labels to protect the printhead.
  • If labels skip or show errors, run Media/Ribbon Calibration from the printer menu.
