Corona wire = Ozone

Laser technology requires a static electrical charging of the imaging drum. This can be accomplished by a transfer roller, which is in direct contact with the imaging drum. This charging process generates little or no ozone.

Brother´s printer uses a corona wire, which charges the imaging drum with high voltage. Toxic ozone accrues in the small gap between corona wire when the imaging drum is charged.

Corona wire: On top of the imaging drum - ozone can emerge.

There is no ozone filter - the fan (picture below) blows the air unfiltered into the environment.

No filter: An ozone filter is not installed.
