OKI MB262 error 393: Troubleshooting guide

The OKI MB262 error 393 is a mechanical alert signaling a problem with paper feeding or a jam detected by the printer's internal sensors. This code occurs if the drive motor detects excessive resistance or fails to pull paper into the system as expected. What is error 393 on OKI MB262? It is a safeguard designed to stop the printer from forcing jammed paper further into the system, which would otherwise risk damaging internal components like the rollers or the laser drum.

Solutions

Quick Diagnosis

If your printer throws the 393 error, first check the input tray. Ensure no torn paper or foreign objects are lodged at the entry point of the transport mechanism.

Step-by-Step Solution

  1. Remove all paper from the input tray.
  2. Look for obstructions in the roller area.
  3. Clean the rubber rollers using a clean, damp cloth to remove paper dust accumulation.
  4. Reload paper with proper alignment and test the print function.

Prevention and Maintenance

Fan your paper stack to separate sheets and prevent static adhesion. Keep the unit clean and away from high-dust environments.

When to Call a Technician

If you find no obstructions and the error 393 continues to trigger despite clean rollers, the internal feed motor might require repair.

Frequently asked questions

This code means there is a paper feed error or a physical obstruction in the feeder path.

No, it is a standard operational jam that usually resolves as soon as the paper path is cleared.

Standard 80g/m2 printer paper works best; heavy stock or thin envelopes can cause frequent jams.

Cleaning every 6 months is good practice to ensure smooth paper handling and prevent slips.
