If the Xiaomi Portable Photo Printer 1S is making unusual noises during operation, please refer to the following methods:
1. Ensure that the printer has not been accidentally dropped or subjected to impact, which can cause the internal components to shift or become misaligned;
2. Look for any foreign objects, such as paper scraps, dust, or debris, inside the printer. These can interfere with the moving parts and cause abnormal noises;
3. Check that the photo paper is properly loaded and not jammed. Misaligned or jammed paper can cause mechanical issues and strange sounds;
4. Contact after-sales service to check whether there is a printer malfunction.
