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.
• Ensure 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 reduce 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.
