Please check the following points to solve the problem:

• Make sure that the paper guides are set correctly. If the guides are too tight or too loose against the paper stack, slide the paper guides to fit the paper size.
  
  
  
• If you are using the manual feed slot, make sure the manual feed paper guides are set to the width of the paper that you are going to use.
  
  
  
  
• The paper tray may be too full. Make sure that the paper is below the maximum paper mark. If the paper is over the maximum paper mark, reduce the quantity of paper until the maximum paper mark appears.
  
  
  
  
  
• Check the paper type and quality.
