Xerox B310 error 031-302: Jam solution

The Xerox B310 error 031-302 occurs due to a failure in the automatic document feeder (ADF) sensor, indicating that the paper is not moving correctly or is jammed. This fault interrupts the scanning or copying function. To fix the 031-302 error on the Xerox B310, we must meticulously clean the ADF optical sensors and check for small paper scraps. This model is very efficient, but the ADF is sensitive to documents with excess glue or staples.

Common causes

  • 1Paper blocking the ADF input sensor.
  • 2Dust accumulation on the ADF sensor lenses.
  • 3Use of documents with staples or adhesives that damage the rollers.
  • 4Sensor failure due to heavy wear.

Solutions

Diagnostic

If the error occurs while using the multiple copy function but not when printing from the PC, the problem is definitely the ADF.

Step-by-Step Solution

  1. Lift the top cover of the automatic feeder (ADF).
  2. Carefully remove any document that might be jammed in the path.
  3. Clean the small optical sensors at the base of the ADF with a dry cloth to remove accumulated dust.
  4. Close the lid and restart the machine to recalibrate the sensors.

Prevention and Maintenance

Avoid inserting documents that have staples, clips, or tape. Perform cleaning with compressed air in the ADF slot every three months.

When to call a technician

If after cleaning the sensors the error persists and the ADF still doesn't recognize the paper, the ADF motor might have failed.
