Note
 Go to http://www.brother-usa.com/environment/
 for instructions on how to return the used toner cartridge 
to the brother collection program. If you choose not to return your used toner cartridge, please discard the 
used toner cartridge according to local regulations, keeping it separate from domestic waste. If you have 
questions, call your local waste disposal office.
 We recommend placing used consumable items on a piece of paper to prevent accidentally spilling or 
scattering the material inside.
 If you use paper that is not a direct equivalent for the recommended paper, the life of consumable items 
and printer parts may be reduced.
 The projected life for each of toner cartridges and a waste toner box is based on ISO/IEC 19798. 
Frequency of replacement will vary depending on the complexity of printed pages, percentage of coverage 
and type of media used.
 
Toner cartridges5
A new toner cartridge can print approximately 2,200 pages (black) or approximately 1,400 pages (yellow, 
magenta, cyan)
1. 
Note
 The toner cartridges that come supplied with the printer are starter toners. A starter toner can print 
approximately 1,000 pages
1.
 The amount of toner used varies according to what is printed on the page and the print density setting.
 If you change the print density setting for lighter or darker printing, the amount of toner used will change.
 Wait to unpack the toner cartridge until immediately before you put it into the printer.

sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
 To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the 
illustration.

water at once.
 To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
 
Note
 Be sure to seal up the toner cartridge tightly in a suitable bag so that toner powder does not spill out of the 
cartridge.
