Recommended Schedule for 
Replacing the Print Cartridge
When the message indicating that the print cartridge is near 
the end of lifespan is displayed on the display screen of the 
operator panel, prepare a replacement print cartridge. You can 
keep printing approximately 250 sheets until the next message 
is displayed.
When the message indicating that the print cartridge ended its 
lifespan is displayed and printing is stopped, replace the print 
cartridge. 
Note
• The actual life of the print cartridge differs depending on the 
usage.
• Do not expose the toner or the toner 
cartridge to fire. The toner might explode 
and  cause burns.
• Do not store toner cartridge close to a fire. 
The toner can ignite and cause fires or 
burns.
• Do not clean up spilled toner with a vacuum 
cleaner; the toner could ignite from sparks or 
other electrical contact. Spilled toner should 
be cleaned up with a wet towel.
• Some parts inside the device become hot 
and can cause burns. Do not touch areas 
labeled "Caution High Temperature".
• Keep toner and toner cartridge out of reach 
of children. If children swallow toner, consult 
a doctor immediately.
• If toner is accidentally inhaled, gargle with 
large amounts of water and get plenty of 
fresh air.  Consult a doctor if necessary.
• If toner gets on hands or skin, wash it off 
with soap and water.
• If toner gets into the eyes, immediately flush 
with plenty of water. Consult a doctor if 
necessary.

Warning
Caution
• When dealing with paper jams or replacing 
toner cartridge, take care not to get toner on 
your hands or clothes. If toner gets on hands 
or skin, wash it off with soap and water.
• If toner gets on clothes, wash in cold water; 
hot water sets the toner into fabric.
• Do not disassemble the toner cartridge. 
Toner may disperse and soil hands and 
clothes or result in accidental inhalation.
• Place used toner cartridge in a plastic bag to 
prevent toner from dispersing.
• If you spill toner, carefully clean it up with a 
wet cloth.
