BIASED MEMBER TO PREVENT CONTAMINATION |
| 摘要 |
A method for preventing contamination of a lens assembly by charged particles on an image bearing surface in an electrophotographic printer includes providing a conductive electrode with an opening adjacent the lens assembly; charging the conductive electrode with a variable voltage power supply; and matching a voltage on the image bearing surface with the variable voltage power supply. |

1. A method for preventing contamination of a lens assembly by charged particles on an image bearing surface in an electrophotographic printer comprising:
providing a conductive electrode with an opening adjacent the lens assembly, wherein said conductive electrode is provided upstream and downstream of the lens assembly with respect to a direction of movement of the image bearing surface; charging the conductive electrode with a variable voltage power supply; and matching a voltage on the image bearing surface with the variable voltage power supply so as to reduce an attractive force between the image bearing surface and the conductive electrode. |
