In software, manually select port USB001. | | Firmware needed | Jinka 721 rarely needs firmware updates. Do not flash unknown firmware – it can brick the mainboard. |
Do not skip this – many “driver issues” are actually software config issues.
This driver is compatible with cutting software like SignMaster, Sure Cuts A Lot, VinylMaster, Easy Cut Studio.
Download mirror (official recommendation):
Go to the manufacturer’s official site (Shenzhen Jinka Tech) – currently jinkatech . com (verify before use). If offline, use the Internet Archive or contact their WhatsApp support for a direct file.
If the official site is down, use the Roland GX-24 driver from Roland’s official support page – it often works because the Jinka 721 emulates Roland commands.
Rating: 4/5 Stars
The driver itself is just the bridge between the computer and the cutter. The real question is: Does it talk to the design software?
Jinka maintains a legacy support page. As of 2025, the direct link is often found via their distributor networks. download driver cutting plotter jinka 721 verified
Even with a "verified" driver, issues arise. Here is the technician’s checklist.
| Symptom | Likely Cause | Verified Solution | | :--- | :--- | :--- | | Device Manager shows "Unknown USB Device" | Windows Update overwrote the CH340 driver. | Download the CH340 Uninstaller from WCH. Reboot. Reinstall using Step 3, Phase A with the USB cable unplugged. | | Test cut works, but production stops halfway | Flow control mismatch or buffer overflow. | Change Flow Control to Hardware (RTS/CTS) . Reduce the "Send Speed" in SignMaster to "Slow". | | Plotter cuts mirror image or upside down | Wrong origin point in software. | On the Jinka 721 keypad, press "Origin" (bottom left). In software, set origin to "Bottom Left". | | Driver installed, but no COM port appears | You plugged the USB in before installing the driver. | Go to Device Manager > View > Show hidden devices. Uninstall any greyed-out COM ports. Reboot. Reinstall driver before plugging in. |

Installing drivers for these "Chinese plotters" often requires specific steps to bypass modern Windows security:
Disable Driver Signature Enforcement: On Windows 10/11, you may need to restart your PC in a special mode (Settings > Recovery > Advanced Startup) and select F7 to disable driver signature enforcement before installing.
USB vs. Serial: If the USB connection is unstable, many users recommend using a Serial (RS-232C) cable with a NULL MODEM, as it often provides a more reliable connection.
Software Configuration: Once the driver is installed, you must configure your software (like ArtCut 2009, SignMaster, or Easy Cut Studio) to point to the correct COM port (usually COM3 or COM4).
Hardware Refresh: If the machine isn't recognized, you can use the Device Manager to uninstall all Universal Serial Bus controllers and restart the computer to force Windows to redetect the plotter.
