Summary: I have had this printer for awhile and used it intermittently. Recently, the OPC belt went out. I'm sure I've printed about 1000 pages with this printer, in total. To replace the belt is about $300.
Summary: While I am very happy with the printer, Brother currently has a very serious supply problem. The printer takes something called a waste toner pack, or WT4CL. This is a little plastic thing that probably costs a dime to produce. The manual says that it lasts about 12,000 pages.
