Question about Brother MFC-7820N Laser Printer
If you just want to REPLACE the toner cartridge, open the front door and jiggle the combined toner & drum units out. push down on a blue tab on the side to release the TN-350 toner cartridge and lift it out of the DR-350 drum cartridge. If you have the toner cartridge out and want to refill it you7rself, DON'T. You can buy toner with about the right size grains, but Brother uses toner with grains that are much smoother and rounder than that aftermarket stuff. The toner is constantly stirred during the print process, and the rough-grained aftermarket toner puts up so much resistance that it often breaks a gear in the body of your MFC. Brother usually doesn't cover that one in their warranty.

The 100/100XL cartridges are not licensed to be refilled. You can, however, refill the 100A or 100XLA cartridges available on the Lexmark website at http://www.lexmark.com. You should be aware that a refilled cartridge will not be able to report its ink level, and you might not get the print quality you expect from ink that is specially formulated by Lexmark to pass through microscopic nozzles at extremely high temperatures.
