Abstract
A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.
