Fujitsu fi-7910NX error E4: Memory Overflow

The Fujitsu fi-7910NX error E4 indicates a memory buffer issue when handling large datasets. This is common during high-resolution scans and usually indicates that the scanner's internal processing capacity has been reached for the current task.

Common causes

  • 1Buffer saturation due to extreme scanning resolutions.
  • 2Host PC connection bottleneck.
  • 3Batch size exceeding current buffer allocation.
  • 4Hardware memory error.

Solutions

Diagnóstico rápido

If E4 triggers during large high-quality scan batches, it is simply a buffer capacity limit being reached. Your PC or software might be lagging behind the scanner's throughput.

Solución paso a paso

  1. DPI adjustment: Reduce resolution to 300 DPI.
  2. Batch size: Split documents into smaller sections.
  3. Software reset: Restart your scanning application.
  4. PC Check: Verify the host PC's RAM availability.

Prevención y mantenimiento

Ensure you are using high-speed data cables. Maintain enough free RAM on your PC and avoid running memory-heavy applications during scanning.

Cuándo llamar a un técnico

If E4 persists even for single, low-resolution documents, the internal scanner memory may have malfunctioned.

Frequently asked questions

The E4 error indicates a memory buffer overflow while the scanner is processing high-resolution image data.

Lower your scan DPI or split large document batches into smaller manageable chunks.

No, E4 is a hardware or software data processing limit, completely independent of the physical document feed rollers.

It is a temporary bottleneck. Restarting the scanner and the application should clear the buffer and allow normal operation.
