  | Background  | Background scatter results from bits of toner distributed on  | ||
  | 
  | scatter | the printed page.  | |
  | 
  | 
  | 
  | • The paper may be too damp. Try printing with a different  | 
  | 
  | 
  | 
  | batch of paper. Do not open packages of paper until  | 
  | 
  | 
  | 
  | necessary so that the paper does not absorb too much  | 
  | 
  | 
  | 
  | moisture.  | 
  | 
  | 
  | 
  | • If background scatter occurs on an envelope, change the  | 
  | 
  | 
  | 
  | printing layout to avoid printing over areas that have  | 
  | 
  | 
  | 
  | overlapping seams on the reverse side. Printing on seams  | 
  | 
  | 
  | 
  | can cause problems.  | 
  | 
  | 
  | 
  | • If background scatter covers the entire surface area of a  | 
  | 
  | 
  | 
  | printed page, adjust the print resolution through your  | 
  | 
  | 
  | 
  | software application or the printer properties.  | 
  | 
  | 
  |

  | Misformed  | • If characters are improperly formed and producing hollow  | |
  | 
  | characters | images, the paper stock may be too slick. Try a different  | |
  | 
  |

  | 
  | Specifications” on page 6.3.  | 
  | 
  | |
  | 
  | • Ensure that the paper or other material is loaded correctly  | 
  | 
  | and the guides are not too tight or too loose against the  | 
  | 
  | paper stack.  |

Curl or wave | • Check the paper type and quality. Both high temperature  | 
  | and humidity can cause paper curl. See “Paper  | 
  | Specifications” on page 6.3.  | 
  | • Turn over the stack of paper in the input tray. Also try  | 
  | rotating the paper 180° in the input tray.  |
