NEC IRIS is a line of office laser printers that use an electrically charged fuser. The fuser is an important component of the printer that heats the toner and presses it into the paper.

The fuser unit contains an electrophotographic imaging drum that the toner transfers to. The fuser also contains a heater that heats the fusing roller. It is possible for the fuser to run at too high of a temperature and begin to melt the plastic casing of the fuser unit.

This can cause a thermal fuse to blow, which prevents the fuser from reaching the high temperatures necessary to fuse the toner. If the fuser unit is melted, you need to replace the fuser unit.
