Curled or wavy
 Check the paper type and quality. High temperatures and high humidity will cause 
paper to curl. See About paper on page 6.
 If you do not use the printer often, the paper may have been in the paper tray too 
long. Turn over the stack of paper in the paper tray. Also, fan the paper stack and 
then rotate the paper 180° in the paper tray.
Wrinkles or creases
 Make sure that the paper is loaded properly. See Printing on plain paper, bond 
paper or transparencies from Tray 1, 2 or 3 on page 11.
 Check the paper type and quality. See About paper on page 6.
 Turn over the stack of paper in the tray or try rotating the paper 180° in the input 
tray.
Envelope Creases
 Make sure that the envelope levers inside the back cover is pulled down when 
you print the envelope.
 
When you have finished printing, open the back cover and reset the two blue levers 
back to their original position.
