Abstract:
A method of improving throughput of media having images fixed by a heat fixing device comprising:assigning weighted values to media being fixed by said fixing device, said values being larger for smaller widths of media and larger for longer lengths of said media, and include a negative for wider media,accumulating weighted values for successive media being fixed by said fixing device as a first count,slowing the movement of media through said fixing device, reducing the temperature of fixing of said fixing device and increasing the time interval between sheets when said first count reaches a predetermined value,accumulating weighted values for subsequent successive media being fixed by said fixing device as a second count, andwhile continuing slow movement of media through said fixing device and reduced temperature of fixing of said fixing device further increasing the time interval between sheets reaching said fixing device to a first time interval when said second count reaches a first predetermined value.
