Print-Quality Troubleshooting
Ink on White Portion of Print
Color on the print where no color should be printed is often called a latent
image. A latent image remains on the Drum when it should have been
transferred to its sheet of paper. An insufficient amount of oil on the Drum,
provided by a dirty, defective, or old Drum Maintenenace Kit may be the
problem. Printing on recycled or 3-hole punch paper commonly causes this
problem.
