Understanding Messages Requesting Toner Container 
Replacement
The printer displays messages for individual colors at two stages of toner 
usage. This message is automatically alternated with the other printer 
message (such as Ready):
• When the printer becomes low on toner, for example in the cyan 
container, the printer displays the message Toner low C as the first 
caution. Note the replacement is not always necessary at this stage. 
• If you ignore the above message and continue printing, the printer 
displays the message Replace toner — just before the toner is 
used up. The toner container must be replaced immediately. Clean 
the separate charger wires, etc. After the cleaning is finished, 
however, the message does not automatically change to Ready. To 
restart printing, you must press [GO] and make the printer ready.
In either case, replace the toner container, refer to Toner Container 
Replacement on page 5-2.

Replacing the Toner Container
This section explains how to replace the toner containers. When 
replacing the toner container of any color, always replace the waste toner 
box at the same time. If this box is full, the printer may be damaged or 
contaminated by the waste toner that may spill over the box. 
IMPORTANT   During toner container replacement, temporarily move 
storage media and computer supplies (such as floppy disks) away 
from the toner container. This is to avoid damaging media by the 
magnetism of toner.
IMPORTANT   Kyocera Mita Corporation is not liable against any 
damages or problems arising from the use of toner containers other 
than those designated as original Kyocera toner containers. For 
optimum performance, it is also recommended to use only the 
Kyocera toner containers which are specifically intended for use in 
your country or region. If the toner container for another destinations 
is installed, the printer will stop printing.
To replace the toner container, first make sure of the color of the toner 
container requiring replacement. In this example, it is assumed that you 
are replacing the cyan toner container.
1Open the top cover (top tray).
2Carefully remove the old toner container from the printer.
CAUTION   Do not attempt to incinerate the Toner 
Container. Dangerous sparks may cause burns.
Note  You do not have to turn printer power off before starting the 
replacement. Any data that may be processing in the printer will 
be deleted if you turn the printer power off.

Turn off the printer’s power, plug in the

another print command. If the problem 
occurs only with a specific file or 
application, check the printer driver 
settings for that application.
The printer is emitting steam in the 
area around the top tray. Check the room temperature to see if it 
is low, or if damp paper was used.Depending on the printing environment 
and the papers condition, the heat 
generated during printing will cause the 
moisture in the paper to evaporate, and 
the steam emitted may look like 
smoke. This is not a problem, and you 
can continue printing.
If the steam concerns you, raise the 
room temperature, or replace the 
paper with a newer, dryer paper.
