SKEW
HEIGHT OF CURL OF OUTPUT PAPER
Note : Measurement conditions
1. Print out 20 sheets of paper continuously in order to stabilize the fuser unit.
2. After the 20 pages are printed out, pick out the 21st to 30th pages as samples, and
wait for 5 minutes before measuring them.
3. Place those papers on a flat surface with their curls facing upward, measure the length
between the flat surface and the tip of the curl of the bottommost paper, similarly
measure the other three corners, and define the largest value of four corners as the
curl value.
