Paper Curl Correction
When paper is exposed to heat, the paper loses moisture and curls toward the heat source. High dry ink/toner coverage jobs tend to curl more due to the dry ink/toner plastification effect on the paper surface.
Many variables can cause Paper curl, which includes:
The weight of the paper and whether it is coated or uncoated
The amount of dry ink/toner and the area that is covered on a sheet: the heavier the coverage, the greater the tendency to curl
How the paper is loaded in the tray, load the paper as instructed on the ream wrapper
The atmospheric conditions of the room where the paper is stored, especially those related to humidity and temperature
The heat generated during the fusing processes
Tip:
Successful paper curl correction varies from day to day. A successful setting used on one day cannot be successful on another day. This is especially relevant if the room in which press is located experiences changes in temperature and humidity.
