Transfer, detac polarity switching |
摘要 |
Method and apparatus for providing multiple colors in a single pass of a copy sheet through a transfer station by switching the polarity of a transfer corotron and automatically adjusting the output of the detac corona device. In particular, a single power supply including high voltage switches responds to color selections to change the polarity of a transfer corotron to charge a copy sheet for toner transfer, and a current sense and precision rectifier stage responds to the copy sheet charge to provide a suitable detac charge independent of the transfer corotron polarity.
