A printing device includes a printing mechanism including a fuser heating element and an image analysis device. The image analysis device performs an image analysis on a print job in order to determine an image density of at least a portion of the print job. A fuser heating element temperature is controlled according to the image density.

Fuser temperature control based on image density

A system and method for minimizing distortion in printed images due to toner explosion receives the incoming image bit stream and monitors the stream for horizontal lines and edges that would be particularly susceptible to toner explosion distortion. When such features are determined, the bit stream is modified to print an outlined area with a fill pattern therein. This decreases the amount of toner used to print the horizontal line or edge. As less toner is required, toner piles transferred to the paper are shorter and, therefore, tend to generate less distortion when toner explosions occur.
