The printer uses four toner cartridges: black, yellow magenta, and cyan. When the 
toner supply in a cartridge begins to run out, the message ‘Replace xxxx Toner (x)’ 
message appears on the operation panel (xxxx is the toner cartridge color). 
Replace toner cartridge(s) as soon as the message prompting you to do so 
appears. The printer will stop operating if you do not replace the toner cartridge 
when required. 

 

 

See 

Toner cartridges are consumables. For more information about consumables, refer 
to Appendix A “Introduction to Options and Consumables”. 
For details about when to change consumables, refer to Appendix D “Life Span of 
Consumables”.

Never throw a used toner cartridge into an fire. It can explode, causing injuries. 

 
 

 

Handling Precautions 

 

• 

Never use a vacuum cleaner to clean toner.  Static electricity could build up and 
damage sensors. 

• 

Do not reuse toner cartridges once you have removed them from the printer. 
Loose toner could spill inside the printer and deteriorate print quality. 

• 

To prevent residual toner form spilling, avoid shaking or bumping used toner 
cartridges. 

• 

After moving a toner cartridge from a cold place to a warm place, allow 1 hour 
for the cartridge to adapt to room temperature before installing it. (This is not 
necessary if there is no condensation.) 

• 

Toner should be still be washed off immediately if it gets on your hands or 
clothing. 

• 

Only use toner cartridges recommended by Brother. Using toner cartridges that 
are not recommended may result in lower print quality and unsatisfactory printer 
performance.
