I have a question about OPC drums in printers.any help?
It's hard to justify buying a new OPC drum when it costs more than a new printer.
Answers:
The drum has a pre calibrated number of pages it will print before it is deemed to be at the end of it's service life. The drum in an integral part to forming the image as it is the part of the printer that attract the toner dust and applies it ot the page.
This unit should be replaced. Your image quality will start to wain very rapidly, and you risk potential damage to your printer.
I don't know what you mean by "Out for a while now" since the drum is an integral part of the printing process and built in to the toner cartridge.
There's simply no way the printer can function without it.

"The OPC (organophotoconductor) drum is the most expensive component of a toner cartridge and drives the entire print process. The OPC drum consists of a nonconductive (organic) coating on a nonferrous (aluminum) substrate. An OPC drum is used in an abrasive environment in which its surface is worn down by toner, wiper blades, and paper dust. "

"To transfer a digital image to paper, laser printers employ a xerographic printing process that requires the near-instantaneous interaction of all its components. The printer shoots a laser beam onto an OPC (optical photoconductor) drum, and the drum’s electrostatic charge attracts a black or colored powder called toner. The toner is then applied to the paper and passed through a fuser that bonds the toner to the paper through heat and pressure. "
