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 DCP very 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.
