Caution:
 The OPC belt is extremely sensitive to bright light and direct sunlight. 
Always leave it in its protective bag until you are ready to install it. Any exposure to 
light should be limited to less than two minutes, or permanent damage could result. If 
you suspect the belt is damaged due to exposure to light, put the belt in a dark place 
to recover. Depending on the amount of exposure, recovery may take up to two hours. 
Recovery time is dependent on the amount of exposure sustained. Recovery is not 
guaranteed.
The OPC belt is also extremely sensitive to touch. Always handle the cartridge so you 
don’t touch the surface of the belt. Any body oil left on the surface of the belt will 
prevent toner from adhering to the belt which results in poor image quality. Also, keep 
the cartridge away from anything that may scratch the surface of the belt. Any 
scratches will show in the image produced.

Note: 
A dry cotton cloth is required for this procedure.
