The transfer corona is responsible for transferring toner from the cartridge onto the paper. If it is faulty, the toner may not be transferred properly, leading to light output. Faulty ink cartridges or a faulty scanner unit would not produce the same result with two different cartridges, and the fuser unit is responsible for melting the toner onto the paper after it has been transferred, so it is less likely to be the cause of light output.
