## Recover from the wrong scan

1. **Choose the work order scan field**

   Choose the work order scan field.

   Focus this field before using a keyboard scanner. Scanning elsewhere must never start a label run.

2. **Scan an unknown reference**

   Scan an unknown reference.

   A missing or ambiguous reference is refused. Do not guess a customer or reuse another order label. Check the paperwork and scan the right reference.

3. **Choose the work order scan field**

   Choose the work order scan field.

   Focus this field before using a keyboard scanner. Scanning elsewhere must never start a label run.

4. **Scan the work order**

   Scan the work order.

   An exact reference selects the current imported snapshot. Check the customer, job revision and line before preparing labels.

5. **Prepare the label**

   Prepare the label.

   Approved rules automatically resolve the customer code, template, decoration, quantity and destination. AI is not deciding what prints on this job.
