Common causes

  • 2Worn-out rubber feed rollers losing grip.
  • 3Debris or small pieces of labels blocking the sensor path.
  • 4Over-tightened paper guides pinching the sheet.

Solutions

Quick Diagnostics

Confirm the error by checking the paper tray's front section. If the error code appears without a visible jam, look for a small piece of paper hiding near the feed rollers that might be masking the sensor.

Step-by-Step Solution

  1. Remove Tray: Pull the paper tray completely out of the printer housing.
  2. Clear Path: Remove any visible paper scraps or obstacles along the feed path.
  3. Re-align Paper: Ensure the paper edges are neatly stacked and the side guides are snug but not tight.
  4. Reset: Push the tray back until it locks and press the green button to clear the status.

Prevention and Maintenance

Use high-quality paper and avoid overfilling the tray. Cleaning the rubber feed rollers with a soft, damp cloth every 3-6 months will dramatically decrease the chance of feed-related errors.

When to Call a Technician

If the machine continues to throw error 31.02 after clearing the area, the internal paper feed sensor might have failed, requiring professional technical repair.
