Abstract
Examples disclosed herein relate to an imaging device. The imaging device to include a discharge member to discharge a first pattern on a photoconductor; and a writing engine to control the discharge member to discharge a second pattern to the photoconductor to obscure any latent pattern formed from the first pattern remaining on the photoconductor.
Claims15
An imaging device, comprising:
- a discharge member to discharge a first pattern on a photoconductor, and
- a writing engine to control the discharge member to discharge a second pattern to the photoconductor to obscure any latent pattern formed from the first pattern remaining on the photoconductor.
A method to obscure an imaging pattern on a drum, comprising:
- determining if the imaging pattern has been written on the drum;
- determining if a security operation is to be performed when the imaging pattern has been written on the drum;
- acquiring a latent image reduction parameter when the security operation is to be performed;
- and
- writing a pattern to the drum according to the latent image reduction parameter, the pattern to obscure any latent pattern remaining from the imaging pattern.

An imaging device, comprising:
- a drum to receive a discharge pattern and a charged particle to be attracted to the discharge pattern;
- a discharge member to apply the discharge pattern to the drum;
- a security parameter engine to store latent image reduction parameters;
- and
- a writing engine to control the discharge member to apply a pattern to the drum to obscure any latent pattern formed from the discharge pattern remaining on the drum according to the latent image reduction parameter.
