When the photo paper is damp, it will absorb dirt and bring it into the device, thus affecting the photo’s quality. Use the [Cleaning the print head] to print out an orange Smart Sheet for cleaning. Repeat 4-5 times to solve the problem. If it is still not solved, try applying alcohol to the orange Smart Sheet and tap the cleaning mode again to clean it.
After the photo paper is opened, it will be affected by temperature and humidity. It needs to be used as soon as possible to avoid affecting the printing quality due to moisture. It is recommended to use a sealed bag to seal the photos.
