Hi, You may need to check the following points:
1. Check whether the bearing or the pulley is issued (the card can be lubricated for lubrication);
2. Check if there is looseness and tighten it properly;
3. Whether the printing speed is too fast, can be adjusted appropriately, the reference range: 30-60mm/s.

I hope this can help you.
