Method of preventing back side of paper from contamination in electrophotography printer |
摘要 |
A back side of a paper is protected from contamination during an operation of the electrophotographic printer. A light scanning unit is warmed up as the main motor operates. This should minimize the potential difference on the surface of the photosensitive drum. A zero or a less than zero voltage is applied to its transfer roller to prevent the toner from adhering to the transfer roller before a paper reaches the transfer roller. This protects the back side of the paper from contamination due to the toner.
