Cleaning the Conductivity Temperature Depth (CTD) Sensor
Note • To prevent electric shock, always turn off the machine and disconnect the power cable from
the grounded outlet before performing maintenance.
Important • Ensure that nothing touches or scratches the surface (black-colored film) of the transfer belt
unit. Scratches, dirt, or oil from your hands on the film of the transfer belt unit may
deteriorate print quality.
• To protect the drum cartridges from overexposure to bright light, close the inner cover within
five minutes. If the front cover remains open for more than five minutes, print quality may
degrade.
1 Make sure that the <Data> indicator light is off and there are no jobs currently in
process.
2 Press the power switch to the [ ] position to
switch the power off.
3 Lift up the latch of the right hand cover to
open the cover.
4 Open the front cover.
5 Rotate the two lock levers of the inner cover
while pressing the cover with the other hand,
and then open the cover.
