Why can’t the ribbon be inserted into the Xiaomi Portable Photo Printer Pro?

If the ribbon cannot be inserted into the Xiaomi Portable Photo Printer Pro, please follow these steps:
  1. Check if there are any foreign objects inside the printer. Remove them from the ribbon slot to restore normal use;
  2. Check whether the ribbon is intact and confirm that it is inserted in the correct direction;
  3. If the ribbon is intact and correctly oriented but still cannot be inserted, power off the printer, then restart it and try installing the ribbon again. (Ensure that the paper tray is properly installed, as the printer cannot perform automatic reset or self-check without it.)
Note:
Always handle the ribbon carefully to avoid possible wrinkles or damage, which can affect print quality and cause feeding issues.
