OKI B721dnw error 380: How to solve paper transport issues

The OKI B721dnw error 380 signifies a paper transport timing failure. The printer expects the paper to hit the exit sensor at a specific moment; if it doesn't, the machine assumes a jam has occurred. This issue often stems from dirty rollers losing their grip or paper being misaligned in the tray.

Solutions

Diagnóstico rápido

If the OKI B721dnw error 380 occurs, look for signs of paper skewing within the feeder tray. If the paper feeds crooked, it will eventually trip the error timer at the exit sensor.

Solución paso a paso

  1. Remove all paper from the primary tray.
  2. Gently clean the paper pick rollers with a damp, lint-free cloth.
  3. Ensure the side guides in the tray are snugly fitted against the paper stack.
  4. Check the inner paper path for small torn fragments of paper.

Prevención y mantenimiento

Routine cleaning of the pickup rollers is crucial for printers with high-volume output. Avoid storing paper in humid conditions, which can lead to slipping during the feed process.

Cuándo llamar a un técnico

If the error 380 persists regardless of the paper quality or roller condition, the paper exit sensor may be blocked by debris or faulty, requiring professional attention.
