Abstract
A continuous-form electrophotographic printer 10 for printing an image onto a continuous-form media 12 includes a media motion assembly 53 which moves the continuous-form media 12 at a velocity initially past an image transfer station 20 and then past an image fixing station 22. An image transfer assembly 28 at the image transfer station 20 transfers an electrophotographic image onto the continuous-form media 12. The media motion assembly 53 includes a roller-fusing assembly 42 at the image fixing station 22 to affix the electrophotographic image to the continuous-form media 12. The roller-fusing assembly 42 includes a fuser roller 44 heated to a predetermined temperature and a fuser temperature sensor 47 adjacent the fuser roller to monitor the fuser temperature. The printer 10 also includes a speed control system 52 which adjusts the velocity of the media (by changing the rotational speed of the motor 50) in accordance with the fuser temperature sensed by the fuser temperature sensor to obtain a predetermined optimum media velocity.
