Cleaning the LED heads
You are advised to clean the LED heads:
> any time you replace a toner cartridge (a LED lens cleaner
is enclosed with each replacement toner cartridge)
> if printing is showing signs of faded images, white stripes
or blurred letters
You can use a LED lens cleaner or dry, soft cloth for cleaning the
LED heads.

the best quality and performance from your hardware.
Non-Oki Original products may damage your printer
