Q. What is photoreceptor drum?
The photoreceptor drum (or, in some photocopiers, belt) is the heart of the system. A drum is basically a metal roller covered by a layer of photoconductive material. In the dark, the photoconductive layer on the drum acts as an insulator, resisting the flow of electrons from one atom to another.
Q. What is the function of photoreceptor drum in printer?

Q. What is an imaging drum?
An image drum is a vital part of a laser printer that is responsible for transferring the toner and image or text to paper. It has several different names, it’s also called the imaging unit, drum unit or photoreceptor drum.
Q. Do I need to replace imaging drum?
Like laser printer toner cartridges, imaging drums too need to be replaced periodically because the coating on the imaging drum can lose photoelectric properties over time. Using inferior quality paper can leave residues on the drum – an unclean or worn out imaging drum can significantly compromise print quality.
Q. Is a drum unit the same as toner?
In short, the toner cartridge is a container that contains the toner powder, whereas the drum unit is an electrically charged cylinder that transfers the powder onto paper.
Q. Can you clean an imaging drum?
You can use a clean, lint-free cloth instead, but a toner cloth is ideal. Wipe down the exterior of the drum to remove loose toner.
Q. How do I know if I need a new printer drum?
Separate drum units last quite a bit longer than a toner cartridge and typically should be replaced after the use of 3-4 toners. Your printer should inform you when it’s time to replace the drum, but you can usually tell your drum is on it’s last legs if you start to see black spots or lines across the page.
