Solutions

Quick Diagnosis

If your system reports it cannot find the printer or shows an USB-COMMS error, first ensure the device is powered on and the cable is connected. If other devices work in that same port, the issue lies with the driver or the specific cable.

Step-by-step Solution

  1. Try another USB port on your computer to rule out a disabled motherboard port.
  2. Replace the USB cable with a certified high-speed one, avoiding excessively long cables.
  3. Device Manager: Uninstall the device, unplug it, and reconnect it so Windows can scan for the driver again.
  4. Update drivers by downloading the latest version from the manufacturer's official website.

Prevention and Maintenance

Do not disconnect the USB cable while the printer is actively sending or receiving data. Keep connectors dry and avoid sharp bends in the cable.

When to call a technician

If you have tested with different cables, ports, and computers and the USB-COMMS error persists, the printer's mainboard might have a hardware failure in its USB interface.
