A photoreceptor drum is a component of a photocopier or printer that contains a photosensitive material. This material is charged by a laser or LED, and the image to be printed is projected onto it to create an electrostatic charge pattern. The toner particles are then attracted to and transferred from the drum onto the paper to create a physical copy of the image.

This information implies that the photoreceptor cells are continuously sending visual signals to the brain. The constant release of neurotransmitters indicates that the photoreceptor cells are actively responding to light stimuli. This activity is crucial for maintaining normal vision and processing visual information.
Photoreceptor
Earthworms have photoreceptor cells to detect light and darkness. These cells help them navigate their environment and determine whether it is day or night. This information is crucial for their survival, as it helps them find food, avoid predators, and regulate their behavior and activity patterns.
Photoreceptor cells and Rod cells are the more known ones. These allow you to see color.
The photoreceptor drum or belt is a xerographic machine manufactured by Xerox Corporation is like the film in a camera. It is the surface upon which a virtual image is placed and from which the real or developed image is created and transfered to the paper that eventually leaves the machine as a copy or a computer print out.
A Toner Cartridge holds toner and dispenses it as needed to make copies (in a copier) or to print pages (in a printer). Another element in xerographic copiers is the photoreceptor drum. This is the surface to which the toner adheres before being transfered to the paper. The photoreceptor has a long but finite useful lifetime and must be replaced occasionally. Some copiers/printers have drum cartridges which can be changed out by the user. The alternative would be to have a service person open the machine and replace the photoreceptor drum. So, a drum cartridge alows the user to replace the photoreceptor drum and a toner cartridge allows the user to replenish toner supplies, both easier than before cartridges were developed for this purpose.
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 914 drum is a photoreceptor drum for the Xerox 914, the first fully automatic plain paper copier. The machine has not been made or maintained for decades. You would probably have to go to a technology museum to find one, although you might ask whether the Xerox Historical Archive, at Xerox Corporation in Webster, NY, might have an extra they can spare.
