Abstract:
1. A method for reducing curl of a media in an imaging device, the imaging device including a decurler having two rollers defining a nip, a first roller having a substantially uncompressible surface, and a second roller having a substantially compressible surface, the method comprising: adjusting an amount of curl of the media induced by the nip by automatically adjusting a penetration of the second roller into the first roller, wherein the adjusting includes: assigning a value to each factor in a set of factors; selecting a group of factors from the set of factors based on a set of conditions; calculating a penetration value based on the group of factors, the adjusting of the penetration of the second roller into the first roller being performed based on the penetration value; and determining if the penetration value is imaginary based on the group of factors, wherein under the condition that the penetration value is imaginary, the calculating of the penetration value is based on a first equation, and under the condition that the penetration value is not imaginary, the calculating of the penetration value is based on a second equation.
