Why does the printing effect of the Xiaomi Portable Photo Printer 1S become worse with the orange Smart Sheet?

If the printing quality is worse when using the orange Smart Sheet, it is due to the photo paper or the Smart Sheet. To ensure proper calibration and print quality, please do not use unofficial photo paper and orange Smart Sheet.
Besides, please use the official orange Smart Sheet with the matching Xiaomi photo paper from the same pack.
Also, make sure the photo paper is stored in a cool, dry place, or it will affect the print quality, cause paper jams, paper removal errors, incomplete prints, etc. It is recommended to store the photo paper in an environment with a temperature between 15℃ and 32℃, and the storage humidity should be 40% to 55% RH.
