If your GoDEX printer (DT, RT, ZX series) stops printing, skips labels, or shows a flashing light with no output, try these proven fixes. Most issues resolve in minutes with the checks below.
This guide covers the top 10 fixes that work for GoDEX RT700i+, DT4x, ZX420i+, and more.
1) Check Power and Connections
Confirm the power cable is seated and the LED is on. Try a different outlet if needed. Check your USB/Ethernet/Wi-Fi connection and ensure the printer is online on your network.
2) Verify the Printer Is Selected in Your Software
In GoLabel, ShipStation, or your shipping app, pick the exact model/port (e.g., GoDEX RT700i+ (USB)). The wrong driver or destination can block output or cause blank labels.
3) Load Labels Correctly
Ensure the printable side faces the print head, and the media guides gently touch the liner. For fanfold labels, feed straight through the rear slot to avoid side drift.
4) Run Auto-Calibration
If the printer canāt detect label gaps, it wonāt print correctly. Hold Feed until the LED flashes, then release. The printer feeds a few labels and stops at the top of the next one. You can also run calibration in GoLabel ā Printer Tools ā Auto Calibration.
5) Clean the Print Head
Power off and let the head cool. Clean the print head and platen roller with isopropyl alcohol (IPA) using a lint-free swab. Let dry fully before printing.
6) Check Ribbon Installation (Thermal Transfer Only)
For RT/ZX models in thermal transfer mode, verify the ribbon is routed correctly with the inked side toward the label surface. If using direct thermal labels, remove the ribbon entirely.
7) Confirm Label Sensor Type
Set the correct sensor in GoLabel/driver:
- Gap Sensor for most die-cut shipping/barcode labels
- Black Mark Sensor only for labels with a dark mark on the liner
Align the physical sensor under the gap/mark track, then re-calibrate.
8) Adjust Darkness and Speed
Faint or uneven print? Increase Darkness (heat) by 10ā15% and lower Speed to ~3ā4 ips for dense barcodes/small text. Set in GoLabel or the printer driver.
9) Update or Reinstall the Driver
Install the latest GoLabel package (includes drivers). Reboot, reconnect the printer, and select the correct port. Outdated/corrupt drivers can block printing.
10) Reset to Factory Defaults
Power off. Hold Feed + Pause and power on until the LED flashes, then release. This clears bad settings and restores default calibration.
Bonus: Check Your Label Stock
Low-quality media leads to poor sensing and adhesive buildup. Use premium thermal rolls (uniform gaps, clean liners). McAuley Labels provides vetted rolls with free shipping.

- How often should I clean the print head?Ā
- Every 1ā2 rolls, or whenever print quality fades. Always power off and let it cool before cleaning.
- My printer skips labels. What should I do?
- Thatās typically a sensing issue. Select the correct sensor (Gap vs Black Mark), reposition the sensor, and run auto-calibration.Ā
