Replacing the Toner Cartridge in a Brother HL-3140CW Printer

Replacing the toner cartridge in the Brother HL-3140CW laser printer is not difficult, but it is not immediately obvious because the toner and drum assembly are joined together. 1) Open the laser printer by lifting the the top part. There are no catches to unlock, so it is easy enough to open: 2) Remove the toner cartridge to replace. It will be one of the four cartridges shaded in green. The entire cartridge assembly lifts right out, there are no latches to unlock: What you have in your hands is two pieces – the toner and the drum – even if it looks like just one part: Disassembled, the two parts look like this: The part in blue is the … Read entire article »
