However, the rollers are very accessible and easy to remove and clean and the toner cartridge is a piece of cake to remove and replace. I haven't gotten into duplexing with it yet and need to get a manual for some of the more complex tasks that it is capable of. It is well built and can be a real workhorse in a small office environment. It goes at about 40 to 45 pages a minute and doesn't even breathe hard. This is a very good high speed laser printer.
