ABSTRACT:
A method for processing a media sheet by advancing the media sheet through a nip in a media processing device is disclosed. The nip is capable of being configured by abuttingly coupling a heater device to a pressure roller. A first heater device temperature of the heater device and a pressure roller temperature of the pressure roller are determined. A signal for configuring the nip is generated upon determining the first heater device temperature and the pressure roller temperature. A second heater device temperature of the heater device is determined on generating the signal. A closure of the nip is verified for advancing the media sheet through the nip based on the first heater device temperature, the second heater device temperature and the pressure roller temperature. The media sheet is advanced through the nip on verifying the nip as closed.
