Cleaning the Printer
The paper transfer unit should be cleaned each time the toner container 
and waste toner box are replaced. 
To maintain optimum print quality, it is also recommended that the inside 
of the printer be cleaned once a month as well as when the toner 
container is replaced. 
It should also be cleaned if streaking or lines appear on printed copies, or 
if printouts appear faint or blurred.

occur if the paper transfer unit becomes dirty. To clean the paper transfer 
unit, you must use the cleaning cloth.

General Guidelines
The table below provides basic solutions for problems you may encounter 
with the printer. We suggest you consult this table to troubleshoot the 
problems before calling for service.
Tips
Printer problems may be solved easily by following the tips below. When 
you have encountered a problem that following the above guidelines will 
not solve, try the following:
• Turn the printer power off and wait for several seconds. Then, turn on 
the printer.
• Reboot the computer which sends the print jobs to the printer.
• Obtain and use the latest version of the printer driver. The latest 
versions of printer drivers and utilities are available at: 
http://www.kyoceramita.com/download/.
• Make sure that the procedures for printing are correctly followed in the 
application software. Consult the documentation supplied with the 
application software.

Nothing lights on the operation panel 
even when power is turned on and the 
fan makes no noise.Check that the power cord is properly 
plugged into the power outlet.Turn off the printer’s power, plug in the 
power cord securely, and try turning on

The printer prints a status page, but 
does not print jobs from the computer.Check the printer cable or the interface 
cable.Connect both ends of the printer cable 
securely. Try replacing the printer cable 
or the interface cable.
Check program files and application 
software.Try printing another file or using 
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.
