Do toner cartridges have waste tanks?

Answer 1

Good question. The answer is yes, sort of. The truth is almost all toner cartridges have both a waste bin and a toner half together. On about 95% of the cartridges that HP builds, the waste bin is attached to the toner half. Canon is about the same ratio, since a good portion of their cartridges are variations of the HP cartridges. But when you get into Brother, Xerox, Samsung, Sharp and others, then you will see on some of those printers you have to buy the halves separately. For example if you owned a Brother HL series printer, like the HL 2140, you would have to, at some point, purchase both the TN360 and the DR360 (with Brother the TN = toner and the DR = drum). The thing here is that even though it has two separate halves, you need to connect them together to form a single unit before you can use them in the printer. The drum half is almost always where the waste bin is located, not just with Brother but on all cartridges. On large commercial copiers it is the same basic setup, with a toner cartridge and a waste bin or in this case a waste tank. The exception here is that the two are not each others halves but two separate units entirely. The idea with having the waste bin/waste tank or drum unit separate is that you won't have to replace the drum or waste bin/tank just because you ran out of toner. I hope this answered your question clearly.
