发明名称 Method for applying pick retry using a modified pick roller force to reduce likelihood of failure to pick top sheet from stack
摘要 A method for applying a pick retry using a modified pick roller force includes operating an actuator in a first duty cycle to cause a pick roller to impose a first force on a media stack ordinarily sufficient to pick and feed a top sheet from the media stack to a media path, sensing whether or not the sheet arrives in the media path, and retrying the actuator in a second duty cycle different than the first duty cycle to cause the pick roller to impose a second force on the media stack different from the first force in response to not sensing the arrival of the sheet in the media path. The second force may be greater than the first force. The second duty cycle may be longer than the first duty cycle. Also, the method includes rotating the pick roller concurrently with or subsequently to operating the actuator.
