The corona wire or corona roller in a typical printing machine holds a voltage of around 5,000 to 10,000 volts.
The voltage applied to the corona wire in a xerographic copier or printer varies depending on the manufacturer and model, however, it is a high voltage. On the other hand, that voltage is applied but is not emitted. It is a static electrical voltage and does not go anywhere (there is no effective current)
The primary corona wire in a printer charges the drum or imaging unit, which helps to attract and transfer toner onto the paper during the printing process.
The purpose of the corona wire on a drum is to create a static charge on the surface of the drum. This charge helps attract toner particles to the drum, allowing for the transfer of the toner onto the paper during the printing process. In essence, the corona wire helps facilitate the printing process by ensuring that the toner adheres properly to the drum and is transferred accurately onto the paper.
Short circuit corona in electrical systems can be prevented by ensuring proper insulation of wires, regular maintenance of equipment, and using surge protectors to prevent sudden voltage spikes. Additionally, following safety protocols and regulations, such as keeping electrical systems dry and free from dust, can help prevent short circuit corona.
In a copier or printer manufactured by the Xerox Corporation, the charge is placed on the photoreceptor by passing it under a charged wire. No flash is used for that purpose. Some copiers do use a flash lamp to illuminate the document to be copied, but that is quite a different thing from "spreading the charge."

Its made of ceramic printed from a screen printing machine once the bottle enters a oven at high temp its impossible to remove the label

In the transmission lines, there is no apparent change in the condition of air(CORONA) surounding the wires if the applied voltage is low.However,when the applied voltage exceeds the certain value,called disruptive voltage !!!

Bcoz, corona effect is only possible in high voltage AC supply due to the frequency. That is, the frequency and the HT voltage causes the arc b/w 2 conductors.so , here the air is act as the arc transmitting medium.we called it as Corona. It is highly impossible in DC bcoz of no frequency.

A corona discharge is the ionization of the surrounding atmosphere after an electrical discharge. This can usually be seen as a glowing of a different color near high voltage conductor points.
Clean the corona wire and wipe the drum with a soft cloth.
In air at sea level, 327 V peak.

yes it produceses ozone
