Fujitsu fi-4121C Error E-10: Scanner Jam Fix

The Fujitsu fi-4121C error E-10 is a common notification signaling a document feed fault or a communication error between the scanner and the software driver. This issue is usually caused by paper residue or dust buildup on the automatic feeder's optical sensors. If you are asking why does my Fujitsu fi-4121C show error E-10, examine the input tray for blockages.

Common causes

  • 1Paper debris: Small document fragments blocking the roller path.
  • 2Dust on sensors: Dust buildup prevents sensors from detecting paper sheets.
  • 3Faulty USB cable: Data loss during communication triggers the error.
  • 4Roller wear: Friction loss prevents the document from advancing correctly.

Solutions

Quick Diagnostics

The E-10 error is signaled by a blinking status LED. Check if there are any paper fragments near the pickup rollers or the exposure glass.

Step-by-step Solution

  1. Open: Lift the top cover of the scanner.
  2. Clean: Remove any jammed document and wipe the rollers with mild isopropyl alcohol.
  3. Sensors: Use a dry cloth to clear the paper detection sensors.
  4. Reconnect: Unplug the USB cable from the PC, wait 10 seconds, and reconnect.

Prevention and Maintenance

Perform periodic cleaning of the feed rollers every 15 days. Avoid scanning documents with staples or clips as they damage the glass and trigger sensor errors.

When to Call a Technician

If the error persists after deep cleaning the sensors and swapping the USB cable, the ADF feeding motor may be faulty.
