发明名称 Differential to reduce skew
摘要 An apparatus includes a differential to receive a primary driving force, and provide a first driving force and a second driving force. A first pick wheel is to transfer the first driving force to a sheet. A second pick wheel is to transfer the second driving force to the sheet. The differential is to balance the first driving force and the second driving force to reduce skew in the sheet and feed the sheet along a feed path of a printer. The first pick wheel and the second pick wheel are aligned perpendicular to the feed path at an offset from the differential.

主权项 1. An apparatus comprising: a body; a differential, provided on the body, to receive a primary driving force and to provide a first driving force and a second driving force; a first pick wheel, coupled to a first axel, to rotate about the first axel to move a sheet along a feed path; a second pick wheel, coupled to a second axel, to rotate about the second axel to move the sheet along the feed path; a first plurality of gears, provided on a first side of the body, that (i) is coupled to the differential and the first axel of the first pick wheel, (ii) enables the first axel to be offset from the differential, and (iii) receives the first driving force and transfers the first driving force to the first pick wheel; and a second plurality of gears, provided on a second side of the body, that (i) is coupled to the differential and the second axel of the second pick wheel, (ii) enables the second axel to be offset from the differential, and (iii) receives the second driving force and transfers the second driving force to the second pick wheel; wherein the differential is to balance the first driving force and the second driving force to reduce skew in the sheet as the sheet is moved along the feed path.
