Step-By-Step Instructions To Replace The Keypad On the Zebra MC9400

Replacing the keypad on a Zebra MC9400 can be a delicate process, but it’s definitely manageable with the right tools and instructions. Here’s a step-by-step guide:

Tools You’ll Need:

1. Replacement Keypad – You need to get the exact replacement for your Zebra MC9400. It’s best to order from Zebra or an authorized distributor.
2. Small Screwdrivers – Usually, a Torx driver (T6 or T8) will work.
3. Plastic Pry Tools – To avoid damaging the casing.
4. Tweezers – To handle small components.
5. Suction Cup Tool (Optional) – Helps with lifting screens or panels.

Steps for Replacing the Keypad:

1. Power Off the Device:

   – Before you begin, make sure the device is powered off to prevent any electrical damage or data loss.

2. Remove the Battery:

   – Open the battery compartment and carefully remove the battery. This ensures the device is completely powered off.

3. Unscrew the Device:

   – Use a small screwdriver to remove the screws holding the back panel in place. Keep track of the screws as they may be different sizes.

   – Once the screws are removed, gently pry open the device using plastic tools to avoid damaging the casing.

4. Detach the Screen/Touch Panel:

   – If the screen is obstructing access to the keypad, carefully detach it using a suction cup or plastic prying tools.

   – Some models may have additional screws securing the screen.

5. Access the Keypad:

   – Once you’ve removed any obstructing parts (screen, back panel), the keypad will either be held in place by clips or adhesive.

   – Gently unclip or peel the old keypad out. Be careful not to damage the underlying connections.

6. Disconnect the Keypad Cable:

   – There may be a small cable connecting the keypad to the main board. Use a pair of tweezers to carefully disconnect it.

7. Install the New Keypad:

   – Align the new keypad with the device and carefully connect the cable to the board.

   – Press the keypad into place and make sure it’s properly aligned.

8. Reassemble the Device:

   – Once the keypad is secured, carefully reassemble the device by reversing the disassembly steps.

   – Ensure that everything is properly snapped into place and all screws are tightened.

9. Test the Keypad:

   – Before you fully seal the device, power it on and test the new keypad to make sure it works properly.

10. Final Sealing:

    – Once you confirm that the keypad is functioning as expected, replace the battery and secure the back panel of the device.

Tips:

– If you’re unsure about the specific part number for the replacement keypad, you can contact MIDCOM for part numbers compatible with the MC9400.

– If you encounter resistance during disassembly, double-check for any hidden screws or clips.
