  • Print media ejection
    Patent number: 9878870
    Abstract: According to an example, to eject print media from an image forming apparatus, a variable page feed velocity of a first page of print media exiting a feed zone is detected. An acceleration value and a deceleration value based on the variable page feed velocity of the first page is calculated. The calculated acceleration is applied to a media movement component in the output zone when the entire first page has cleared a media sensor in the front of the output zone, and the deceleration is applied when the tail end of the first page is in a brake zone. In some examples, a second page of print media and a variable page feed velocity of the second page exiting the feed zone is detected, and the media movement component in the output zone is accelerated to match the variable page feed velocity of the second page.
