Solutions

Diagnóstico rápido

If the scanner appears with a yellow triangle in Device Manager or isn't detected at all, the E-601 communication fault is occurring. Start by ruling out physical connection issues before troubleshooting software layers.

Solución paso a paso

  1. Power Cycle: Turn off the device, disconnect, and wait 30 seconds.
  2. Switch Ports: Connect directly to a back-panel USB 2.0 port on the PC.
  3. Update Driver: Remove all previous scan software and perform a clean install of the latest official drivers.
  4. Cable Test: Swap the current cable for a new, certified USB A-B cable.

Prevención y mantenimiento

Avoid using long USB extensions without a repeater, as they degrade signal strength. Ensure firmware is updated to enhance compatibility with modern Windows environments.

Cuándo llamar a un técnico

If testing on a different computer with a known good cable fails, the scanner's internal USB port hardware may be faulty.
