Check 3: Load the paper after correcting its curl.
For Plain Paper 
Turn the paper over and reload it to print on the o ther side.
Leaving the paper loaded on the Rear Tray for a long  time may cause the paper to curl. In this
case, load the paper with the other side facing up.  It may resolve the problem.
W e recommend putting unused paper back into the pac kage and keeping it on a level surface.
For Other Paper 
If the curl on the four corners of the paper is more than 0.1 inch / 3 mm (A) in height, the paper
may be smudged or may not be fed properly. In such  cases, follow the procedure described
below to correct the paper curl. Page 402 of 468 pages

is not curled inward. In such cases, follow the pro cedure described below to curl the paper
outward within 0.1 inch / 3 mm (B) in height before  printing. This may improve the print result.
(C) Printing side
