Cleaning the LED Array
Clean the LED array every time you install a new toner cartridge. A dirty
LED array could cause faded vertical areas or light printing down a page.
1. Press the OPEN button and lift the printer cover all the way up.
2. Locate the LED array on the underside of the cover. Remove the LED
Lens Cleaner Pad (included with the Toner Kit) from the package and
carefully run it along the LED array.
Note: If you do not have a lens cleaner pad, you can use a lint-free cloth
with a little rubbing alcohol on it to clean the LED array.
3. Close the printer cover.
Note: An extra LED cleaning pad is provided with each toner cartridge.
Clean the LED array between toner changes if faded vertical stripes
appear.
