   TROUBLESHOOTING AND ROUTINE MAINTENANCE

Curl or wave

Check the paper type and quality. High temperatures and high humidity 
will cause paper to curl.
If you don’t use the printer very often, the paper may have been in the 
paper tray too long. Turn over the stack of paper in the paper tray. Also, 
try fanning the paper stack and then rotating the paper 180° in the paper 
tray.
Try printing using the straight-through output path. (See
