Why does Pro have an extra safety switch?
 This safety switch is for the TCRU customers, who remove the toner supply
unit by themselves.
 When the toner supply unit is removed, there is nothing to cut off the laser
beam from laser unit. To prevent this, an extra safety switch was added to
turn off the laser unit while the toner supply unit is removed from the
machine.
 TCRU is performed ONLY in the Pro version. In the Office model, the toner
supply unit is removed ONLY by the technicians. Therefore, this safety
switch is not installed in the Office version.
