Fujitsu fi-4340C error E-04: Motor Issue
The Fujitsu fi-4340C error E-04 is a system warning indicating an irregularity in the drive motor performance. This alert is triggered when the motor encounters excessive resistance while trying to feed documents through the Automatic Document Feeder (ADF), typically due to accumulated dust or paper jams. Resolving this usually involves a physical inspection of the paper path to clear any mechanical blockage.
Common causes
- 1Mechanical jam: Poorly inserted paper blocking rollers.
- 2Dirty rollers: Dust accumulation reducing traction.
- 3Consumable wear: Roller kit degraded by usage.
- 4Electronic fault: Short circuit in the drive motor controller.
Solutions
Quick Diagnosis
If the motor emits a strained sound while trying to scan and the E-04 error pops up on the PC, a clear obstruction exists in the paper path. Ensure no remnants of previous pages remain inside the mechanism.Step-by-Step Solution
- Open: Open the ADF cover.
- Inspect: Use a flashlight to see rollers and look for paper scraps.
- Clean: Wipe traction rollers with a cloth dampened in isopropyl alcohol.
- Reset: Close the cover and restart the scanning software.
Prevention and Maintenance
The roller kit (pickup roller) is a consumable that should be replaced every 50,000 scans to prevent unnecessary friction. Never use documents with glue or tape, as these degrade the motor's traction surface.When to Call a Technician
If rollers are clean, no jams are visible, and the motor continues to show resistance or make unusual noises, the fault may be electrical.Technical Data

Frequently asked questions
Error E-04 signals an obstruction or excessive resistance in the ADF drive motor, usually due to debris.
No, never lubricate the motor yourself. Regular roller cleaning is sufficient for maintenance.
Remove staples and clips before scanning and clean the rubber rollers periodically.
If errors continue after cleaning, the intake roller kit may be worn out and needs replacement.
