Abstract: A cleaning brush is not made slidably contact suctioning endless belts which pass inlets, and the cleaning brush is made slidably contact non-suctioning endless belts which do not pass the inlets. Consequently, it is possible to bring out paper dust and transfer remaining toner which adhere to the suctioning endless belts in attracting areas in which the inlet holes are formed, to the exterior of the apparatus by means of sheets to be conveyed. By contrast with this, from non-suctioning endless belts, the cleaning brush can clean and remove paper dust and transfer remaining toner which adhere to the non-suctioning endless belts.

Abstract: A method of error correction in a printing system includes engaging a sheet of print media with a perfector arm and detecting a relative position of the perfecter arm with respect to the sheet of print media when the perfecter arm has engaged the sheet of print media, the detecting being performed using a homing sensor that is configured to sense the perfecter arm while the perfecter arm is engaged with the sheet of print media. The relative position of the perfecter arm with respect to the sheet of print media is compared with an expected relative position and any difference between the relative position and expected relative position is compensated for when feeding the sheet of print media with the perfector arm to a print engine.

Abstract: A first convey roller conveys a sheet in a sheet conveying direction such that a leading edge of the sheet passes through a nip of a second convey roller disposed downstream from the first convey roller. The second convey roller rotates in a reverse direction by a first rotation amount corresponding to a first linear distance to convey the sheet in a direction opposite to the sheet conveying direction, such that the leading edge of the sheet is released from the nip of the second convey roller. In response to the rotation of the second convey roller in the reverse direction, the first convey roller rotates by a second rotation amount corresponding to a second linear distance in the reverse direction to convey the sheet in the direction opposite to the sheet conveying direction, such that the leading edge of the sheet contacts the nip of the second convey roller when the first convey roller has rotated by the second rotation amount and the second convey roller has rotated by the first rotation amount.

Abstract: A second driven roller that is rotated by following a second driving roller has a larger outer diameter than a first driven roller. A front edge of a recording sheet being lifted up from a first nip contacts the second driven roller, and hence the front edge does not directly hit the first driven roller. The second driven roller rotates at a higher rotational speed than a rotational speed of the first driven roller. The second driven roller gently flips the front edge of the recording sheet which has contacted the second driven roller, and leads the front edge quickly to the first nip. The front edge of the recording sheet is smoothly led to the nip.
