Tray 2 Not DetectedMFC-L8900CDW

Fix Tray 2 Not Detected Error on Brother MFC-L8900CDW

The 'Tray 2 Not Detected' error on the Brother MFC-L8900CDW occurs when the main unit fails to establish a connection with the optional paper tray (LT-330CL). This prevents the device from recognizing the additional paper capacity. Often, this is caused by dirty electrical contacts or physical misalignment between the chassis and the tray.

Common causes

  • 1Loose physical connection: Electrical contacts between the tray and base are not mating.
  • 2Sensor dust: Paper dust buildup blocking the tray presence actuator.
  • 3Surface misalignment: The device is on an uneven surface, causing a pin gap.
  • 4Sensor failure: The mechanical tray actuator has physically broken.

Solutions

Diagnóstico rápido

If the error message persists despite the tray being inserted, the issue is likely due to the tray presence sensors or electrical contacts. Ensure the unit is on a level surface and check for debris in the rails that could prevent a solid connection.

Solución paso a paso

  1. Remove Tray 2 entirely and confirm it is completely empty.
  2. Inspect the electrical contacts at the rear of the tray and the corresponding pins on the printer base; clean them with a dry cloth.
  3. Reinsert the tray firmly until you feel a secure click on both sides.
  4. Reset paper settings via the printer's menu under 'Settings' > 'Tray Settings' to refresh the detection of the peripheral.

Prevención y mantenimiento

Avoid sliding the printer across rough floors as it can misalign the connector pins. Clean the feed rollers on the tray every 10,000 pages to prevent paper jams that strain the detection sensors.

Cuándo llamar a un técnico

If cleaning the contacts does not resolve the error, the tray detection sensor or the connection module may be faulty. Contact a qualified technician for component replacement.

Frequently asked questions

It's not a critical error, but it limits your machine's paper capacity, forcing more frequent refills of the primary tray.

Yes, you can continue printing using the primary tray, but the system will ignore Tray 2 until the issue is fixed.
