Abstract
A method for calculating a print medium pick time for an imaging apparatus that transports media at variable speeds along a media path, includes the steps of providing a staging process for varying a transport velocity of a media sheet before transferring an image to the media sheet at the image transfer location, the staging process being used for positioning a top writing line margin of the media sheet in relation to the image at the image transfer location; determining a time period t1 corresponding to a time when a pick motor is started to pick the media sheet to a time when the staging process is started; determining a derived time period t2 representative of a normalized time from when the staging process is started to a time when a media path sensor senses the media sheet; and determining a compensated calculated pick time for the media sheet by summing the time period t1 with the time period t2.
