Why does the machine display "Battery Weak!" or "Check Battery!"?

Description of Solution 200000028624

If the batteries are weak or the wrong power adapter is used, it can cause the machine to display “Battery Weak!” or “Check Battery!”.


1. If using batteries, replace ALL six “AA” batteries, NOT just two or three batteries.


2. If using an AC power adapter, check the rating of the adapter. The label on the adapter should list the model as the AD24ES or AD24, a Switching Adapter with the OUTPUT of 9VDC 1.6A.  The label should also indicate the + POSITIVE and the - NEGATIVE contacts of the adapter plug.  The outside surface of the tip of the plug should be + POSITIVE and the inside contact should be - NEGATIVE.  Using a wrong adapter can DAMAGE the machine internally and void the warranty.  The recommend adapter for this machine is the AD24ES or AD24.  You can order the adapter directly from Brother Accessory Sales Department at 1-877-552-6255 or at our website at
