Zebra ZT600 Series — Compatible Labels & Ribbons
The Zebra ZT600 series is Zebra's high-performance industrial line, built for round-the-clock, high-volume printing in demanding environments. Like the ZT400, it takes full-size 3-inch-core label rolls and long thermal transfer ribbons, making it a common choice for compliance labelling, product identification and heavy shipping operations.

Zebra ZT600 Series setup, calibration & troubleshooting
Everything below is taken from the manufacturer’s own documentation for this series. Most media faults are one of three things: the wrong sensor mode, a printer that has never been calibrated to the label you loaded, or a roll the printer cannot physically take.
Procedures below come from the ZT610/ZT620 User Guide (colour touch display). They do not cover the ZT610 with the 600 dpi Micro Label Printer option, which loads differently.
How to load media in a ZT600 Series printer
- Raise the media door.
- Remove and discard any tags or labels that are torn, dirty, or held on by adhesive or tape.
- Load the media. A roll goes on the media supply spindle, pushed as far back as it will go. Fanfold stock feeds either from behind the printer or from underneath it through the bottom access slot — the path from there is identical.
- Open the printhead assembly by rotating the printhead-open lever upward.
- Turn the media guide adjustment knob until the media guide slides all the way out.
- From the media spindle, feed the media under the dancer assembly, through the media sensor, and under the printhead assembly. Slide it back until it touches the inside back wall of the media sensor.
- Turn the media guide adjustment knob until the guide just touches the edge of the media.
- If you are running thermal transfer stock, load a ribbon now. Direct thermal media needs none.
- Lock the printhead down and close the media door.
The printhead may be hot enough to burn — let it cool before reaching past it. You do not have to switch the printer off to load media, though Zebra recommends it; if you do, any temporary settings such as loaded label formats are lost.

Calibrating the ZT600 Series to your labels
Calibrate whenever you change to a label of a different size, a different material, or a different sensing type — the printer stores thresholds for the last stock it saw.
Media sensing: gap / die-cut (transmissive), black mark (reflective) and continuous / no sensing. The transmissive sensor reads gap and notch die-cut labels; the reflective sensor reads black-mark media. Set Print > Sensors > Sensor Type and the media type (Continuous, Gap/Notch or Mark) to match the stock you actually loaded — a mismatch here is the most common reason labels feed through blank or the printer reports being out of media with a full roll fitted.
Quick calibration: Home screen > Wizards > Print > Start Print runs the print wizard, which auto-calibrates and prints a test label.
- Touch Print > Sensors > Manual Calibration, then Start Calibration.
- Follow each on-screen prompt exactly, touching Next to advance. You will be asked to remove labels from the backing and slide the bare backing under the sensor.
- Press and hold CANCEL at any point to abandon the calibration.
- When calibration completes, press PAUSE to leave pause mode and resume printing.

Connections and finding the printer’s IP address
Standard: USB 2.0, Wired Ethernet (10/100) and RS-232 serial. Optional: 802.11ac Wi-Fi, Bluetooth Classic and Bluetooth LE, Parallel and Applicator interface.
To find the IP address: On the Home screen, touch the Printer Info tab and read the IP address from the display, or touch Menu > Networks > Print: Network Info to print a network configuration label.
To reset the network settings: Set a static address under Connection > Networks, with the IP protocol set to PERMANENT, then reset the network. Ask your network administrator for the correct values.

ZT600 Series indicator lights and what they mean
| Indicator | What it means |
|---|---|
| STATUS steady green | The printer is ready. (Other lights show steady yellow for two seconds during power-up.) |
| PAUSE steady yellow | The printer is paused. |
| STATUS steady red + SUPPLIES steady red | The media supply is out. The printer cannot continue without user intervention. |
| STATUS steady red + SUPPLIES flashing red | The ribbon supply is out. The printer cannot continue without user intervention. |
| STATUS steady yellow + SUPPLIES flashing yellow | The printer is in direct thermal mode, which needs no ribbon, but a ribbon is installed. |
| STATUS steady red + PAUSE steady yellow | The printhead is open. The printer cannot continue without user intervention. |
| STATUS steady yellow | The printhead is over temperature. Allow it to cool before touching it. |
| STATUS flashing yellow | Either the printhead is under temperature, or the main logic board or power supply is over temperature. |
| STATUS steady red + PAUSE steady red + DATA steady red | A non-genuine Zebra printhead is fitted. Install a genuine Zebra printhead to continue. |
| STATUS flashing red | The printer cannot read the dpi setting of the printhead. |
| NETWORK off | Wired Ethernet option: no Ethernet link is available. |
| NETWORK steady green | Wired Ethernet option: a 100 Base-T link was found. |
| NETWORK steady yellow | Wired Ethernet option: a 10 Base-T link was found. |
| NETWORK steady red | Wired Ethernet option: an Ethernet error exists — the printer is not connected to your network. |

Print quality problems on the ZT600 Series
General poor print quality
Print darkness or speed is set wrong, or the label and ribbon are not a matched pair for the job.
Run Menu > Print > Print Quality and set darkness to the LOWEST setting that still gives good print — too high burns through the ribbon, blurs the image and wears the printhead early. Slower speeds print better. If it persists, the label/ribbon combination is wrong for the application.
Fine angular grey lines on blank labels, or long tracks of missing print
Wrinkled ribbon, or a damaged print element.
Treat wrinkled ribbon first (below). Long tracks of missing print across several labels usually mean a damaged print element — that needs a service technician.
Wrinkled ribbon
The ribbon is coated on the wrong side for this printer, was loaded incorrectly, or the burn temperature is too high.
Check the coated side first: these printers need coated-side-out (CSO) ribbon, and a coated-side-in ribbon cannot be used at all. Then re-load it squarely, and bring the darkness setting down.
Loss of print registration, or skipped and mis-positioned labels
Dirty platen roller, media guides set wrong, wrong media type selected, media loaded badly, or the printer has never been calibrated.
Clean the printhead and platen roller, seat the media guides against the edge of the roll, set the media type to match the stock you actually loaded (gap/notch, continuous or mark), then calibrate.
