1. A method of adjusting cycle-up criteria of a printing device based on estimated noise levels and printing an image, comprising: obtaining a current estimated noise level; adjusting the cycle-up criteria according to the estimated noise level; comparing at least one signal, from which the noise level is estimated, with at least one target value; calculating the difference between the signal and the at least one target value; comparing the calculated difference between the signal and the at least one target value with the adjusted cycle-up criteria; and initiating a print job if the calculated difference falls within the adjusted cycle-up criteria.
