design cuts down on waste.
•Automatic color balance adjustment: in order to ensure consistent
output at all times, the machine automatically performs a color
check when the machine is switched on, when the top cover is
opened and then closed, and adjusts the color balance
automatically. It can even be set to adjust the color balance during
long print runs.
•Auto media detect: detects the weight of the media being fed
through the printer then automatically adjusts the fusing
temperature, speed (if necessary) and transfer voltage to ensure
correct fusing and print quality.
