Safety Warning
IMPORTANT!

Always power off and disconnect power on the printer before performing maintenance work. Not doing so means there is a risk of electric shock, short circuit, and damage to the printer or surrounding area.

When a maintenance task necessitates the printer being powered on, use insulated gloves for safety and pay special care not to pinch, damage, or put pressure on any exposed wires, connectors, or circuit boards. Additionally, the nozzle can be extremely hot so never touch it with exposed skin.

Remove the Chamber Temperature Sensor

Step 1: Disconnect the Cables

Open the access end of the AP board cover, then disconnect the chamber temperature sensor cable from the AP board.

Step 2: Remove the Chamber Temperature Sensor

Locate the chamber temperature sensor inside the front cross beam. Remove the two screws (BT3x6) with an H2.0 Allen key, then remove the sensor.

Install the Chamber Temperature Sensor

Step 1: Install the Chamber Temperature Sensor

Align the new chamber temperature sensor with the screw holes on the printer beam, and tighten the two fixing screws (BT3x6) using an H2.0 Allen key.

Please hold the chamber temperature sensor in place while tightening the first screw, then tighten both screws together.

Step 2: Connect the Cables

Route the chamber temperature sensor cable along the cross beam to the side of the AP board, connect it to the AP board, and refasten the inspection end of the AP board cover.

Verifying Functionality

Connect the power supply and turn on the printer, then check whether the chamber temperature is normal.
