Abstract

Il dispositivo di ventilazione per una fotocopiatrice aspira aria mista a ozono dal gruppo di sviluppo e trasferimento dell'immagine e la invia a ventilare il gruppo fusore dove il riscaldamento conseguente dell'aria riduce l'ozono contenuto. Inoltre il flusso d'aria asporta l'acqua di condensa emessa dai fogli di carta durante il fissaggio.
