Name it wrong and you adjust the wrong place
One bar sits at a fixed place after the gap or the gripper. If you treat it as another defect, you skip this step: reduce bearer shock or check the gap, and do not change the ink first. Legal text and the barcode decide whether it ships. They do not decide what it is called.
How to tell them apart
| What you see | Closer to | How you separate them |
|---|---|---|
| One bar at a fixed place after the gap or the gripper. | Plate bounce | Naming it from one white spot |
| Gear marks are many bars at the tooth pitch. Bounce is often just one bar. | Handle it as that other defect | Using the same adjustment |
| The bar sits on the legal text or the barcode | Hold this area first | Ignoring the position just to name it |
Confirm it on the spot
- Look by eye or with a loupe: one bar at a fixed place after the gap or the gripper.
- Rule it out: gear marks are many bars at the tooth pitch, and bounce is often just one bar.
- Reduce bearer shock or check the gap. Do not change the ink first.
