Make test copies or prints on the paper for which you have adjusted the machine and check the
condition of the printouts�
• Repeat steps 1 to 4 to adjust the curl correction level until the paper does not curl when it is output�
NOTE
The regular procedure is to set the level of curl correction in advance to suit the characteristics of each type of paper�
This is because the curl in the paper depends on the paper's materials and basis weight� However, if significant
changes in the environment, such as temperature and humidity, occur for some reason, and the changes temporarily
affect the condition of the paper, such as moisture content, the curl may not be corrected to your satisfaction� If this
happens, see the following and adjust the level of the curl correction for the paper source in which you have loaded
the paper for which you want to calibrate the machine�

the printouts are still curled even if you print on the back side of the paper, follow the procedures described
above to adjust the curl correction level�
