Q: What is the function of a laser printer drum ?
A: Its primary role is to attract the toner particles by way of electrostatic polarities. The laser printer drum operates as the photo conductive unit which serves as the image processing core. Basically, it is a set of parts that specifically work to transfer and paint a digital image right into the surface of the drum. The document to be printed is transformed into a raster image by the computer and sent into the printer. These processes take place during printing.
A: The HL-L2320D uses a DR630 drum unit.
Q: Is this the toner or just the casing for the toner?
A: Drum and toner
Q: if the drum has no toner, then how does it produce the 12000 pages of print
A: Toner and Drum replaced separately. This way you don't waste toner when drum gives out. I purchased toner at the same time, but will not install the toner until machine runs out.
Q: HOW MANY COPIES WILL YOU GET OUT OF THE DR420 DRUM
A: Mine just stopped at 13,090. I wonder what would happen if I turned the counter back and used the old drum/ My copies were fine. Willie
A: Ink is in the toner cartridge (TN-420). They are separately replaceable so no toner is discarded.
