If the printed image is slanted on the particular paper (such as thin paper) only, this feature may enable you to adjust the transferring position of the paper.
The skew correction roller is located in the feeding unit of the marking engine. It adjusts the registered position of fed paper by pushing the paper diagonally against the wall inside the feeding unit. If the setting of skew correction level is incorrect, the printed image is slanted.
