Industrial-grade setup guide for Zebra ZD-series desktop printers with linerless label capability.

20 minutes Medium Models: ZD420, ZD421, ZD620

Setup Steps

  1. 1

    Access media compartment

    Press the release latches on both sides of the printer to open the media cover. Lift the cover fully.

  2. 2

    Install linerless platen roller

    If not already installed, replace the standard platen roller with the linerless-specific roller kit (sold separately).

    Warning: Using linerless media without the correct platen roller can cause adhesive buildup and printer damage.

  3. 3

    Load the media roll

    Place the roll on the media hanger with labels facing up. Adjust the media guides to match roll width.

  4. 4

    Thread through guides

    Route the media under the media guide, over the platen roller, and out the front of the printer.

  5. 5

    Close and calibrate

    Close the media cover. Press and hold the PAUSE button to initiate automatic media calibration.

  6. 6

    Configure via ZPL

    Send ZPL commands or use Zebra Setup Utilities to configure: media type (continuous), print speed, and darkness.

    Tip: For linerless, set media tracking to continuous mode (^MNM in ZPL).

  7. 7

    Set label length

    Configure the default label length in your print driver or via ZPL command (^LL).

  8. 8

    Test print

    Print a configuration label and sample labels to verify all settings are correct.

Troubleshooting

Adhesive buildup on rollers

Solution: Clean rollers with Zebra cleaning cards or isopropyl alcohol. Consider increasing cleaning frequency.

Media out error with paper loaded

Solution: Recalibrate media sensors. Check that media is routed correctly through all guides.

Poor print quality at edges

Solution: Verify media guides are properly adjusted. Check print head alignment and pressure settings.
