Color appearing on blank areas can be caused by a latent image from previous print. Latent
images typically result from insufficient oiling of the Drum. Insufficient oiling is often the result
of a defective or expended Drum Maintenance Unit. Printing on pre-punched media can also
contribute to latent images. Debris in the paper path or faulty Drum Thermistor can also be
possible causes.
