Printer media feed encoder apparatus and method |
摘要 |
A printer with a media feed apparatus has a media tray with a surface for supporting a stack of media sheets. A wave drive mechanism above the stack support surface has a media contact element operable to make contact with a top sheet of a media stack in the tray while moving in a feed direction to shift the top sheet in the feed direction. An encoder above the tray operates to detect motion of the top sheet. A controller may monitor the encoder to determine the speed of sheet motion, and set the speed of the wave drive mechanism to maintain the sheet motion above a threshold.
