In English,

Dirty contacts on Upper Right Cover Safety Switches. Toner gets inside the Upper Right Cover Safety Switches, which can lead to lower DC voltage being applied to the Laser Diode

or Italian,

Dirty contatti su Upper Right Cover interruttori di sicurezza . Toner penetra all'interno del coperchio in alto a destra interruttori di sicurezza , che può portare ad abbassare tensione continua applicata al diodo laser
