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 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)
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."
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.
The corona wire or corona roller in a typical printing machine holds a voltage of around 5,000 to 10,000 volts.
A laser printer uses static electricity to attract toner particles onto the paper before fusing them in place. The printer's photoconductive drum becomes positively charged with electricity by a corona wire, which attracts negatively charged toner particles. This process allows the toner to adhere to the paper in the desired patterns before the fusing process fixes it permanently.
It's a component in a laser printer that Fuses the toner to the paper.
Photo Sensitive Drum, cleaning blade, and primary corona wire
A positive charge on the transfer corona wire attracts negatively charged toner particles from the drum onto the paper as it passes through the printer. This helps in transferring the toner image onto the paper during the printing process.

A transfer corona it's a thin wire usually protected by other thin wire that applies a positive charge to the paper drawing the negative charge particle's on the paper.
A scratch on the laser printer drum can account for black lines showing up on printouts. Another culprit can be a dirty primary corona wire.
Clean the corona wire and wipe the drum with a soft cloth.

Replace the paper in the input tray with new paper. Remove and replace the primary corona wire - is NOT a "quick" solution, so the answer should be "Replace the paper in the input tray with new paper." - Then, power cycle printer if this fails. http://helpdesk.princeton.edu/kb/display.plx?ID=9265
