OKI ES9160 MFP error 04: Transport system failure

The OKI ES9160 MFP error 04 is a technical incident code alerting to a failure in the paper feed through the device's transport system. This error occurs when a sensor fails to detect paper presence within the expected time window, indicating an internal jam or traction problem. To solve the error 04 on an OKI ES9160 MFP, it is imperative to conduct a thorough inspection of the paper path. This unit is a high-performance device designed for large print volumes.

Common causes

  • 1Incorrect paper weight or damaged edges preventing constant flow.
  • 2Paper dust buildup on passage sensors causing false readings.
  • 3Worn traction rollers lacking sufficient grip.
  • 4Fuser unit components with residues delaying sheet transit.

Solutions

Rapid Diagnosis

If your machine stops abruptly with error 04, the system has detected an anomaly in the paper path. Check if the paper is wrinkled or if sheets have stopped mid-way in the exit or fuser area.

Step-by-Step Solution

  1. Opening: Open the side doors and trays.
  2. Extraction: Carefully pull any jammed paper in the direction of the paper flow.
  3. Sensor Verification: Ensure paper sensor flags are not stuck in the "paper detected" position.
  4. Cleaning: If there are residues, clean the feed rollers with a slightly dampened cloth.
  5. Closure: Close all covers so the machine initiates its recognition cycle.

Prevention and Maintenance

Using poor-quality, damp, or wrinkled paper is the main cause of this error. Keep paper in a dry environment and do not exceed tray capacity. Clean the rubber rollers periodically.

When to Call a Technician

If the error 04 persists after clearing the paper path and confirming no visible jams, an optical sensor might be faulty, or the transport motor lacks sufficient power, requiring professional intervention.

Steps to follow

  1. 1

    Open trays

    Unlock and open all paper input trays.

  2. 2

    Sensor reset

    Close all covers firmly to allow the sensors to reset.

Frequently asked questions

Error 04 means the transport system detects that the paper did not reach a specific sensor within the programmed time.

Forcing the jammed paper incorrectly could damage the drum or transfer rollers.

It uses the high-capacity ES9160 series toner.

Keep the tray paper guides adjusted to the exact size of the loaded paper.
