Brother MFC-9070 用户手册

Install the drum unit into the machine. (See Replacing the Drum Unit, page 135.)

Close the top cover.

The machine can print approximately 2,200 pages with one toner cartridge (TN-8000). When the 
toner cartridge is running low, the display shows CHANGE TONER. The machine is supplied with 
a starter toner cartridge that must be replaced after approximately 2,200 pages. Actual page count 
will vary depending on your average document type (i.e. standard letter, detailed graphics). The 
above specifications relate to a 5% black coverage A4 size document.

It is a good idea to keep a new toner cartridge ready for use when you see the toner low warning.

Discard the used toner cartridge according to local regulations. If you are not sure of them, consult 
with Brother dealer for service. Be sure to seal the toner cartridge tightly so toner powder does not 
spill out of the cartridge. When discarding used toner cartridges, keep them separate from domestic 
waste.

It is recommended that you clean the machine when you replace the toner.

The display shows TONER EMPTY to indicate that the toner is empty. Once this indication 
appears, the machine will not resume printing until you have installed a new toner cartridge.
