⚙️ Model Compatibility: Essae SI-810PR Label Scale[cite: 10].
The "Stock NOT there!" error occurs if internal inventory tracking is enabled and the available PLU stock is less than the item weight or quantity you are trying to transact[cite: 10].
How to Fix:
A store manager must update the PLU stock levels[cite: 10].
1. Enter Menu > Programming > Inventory[cite: 10].
2. Enter the PLU Number and press the [PLU] key[cite: 10].
3. Enter the newly arrived stock value and press the [Stock] soft key to add it to the existing inventory[cite: 10].
