Abstract
In a fusing apparatus, such as used in xerography, two rolls form a nip therebetween. A guide member is positionable to direct a sheet approaching the nip to enter the nip at an angle so that an arc or buckle is created in the sheet between a marking station and the nip. The arc or buckle is helpful in avoiding the transfer of mechanical energy from the fusing apparatus to the marking station. As the trailing edge of the sheet exits the marking station, the guide member is positioned to straighten the sheet.
Claims12
In a printing apparatus, a method of conveying a sheet from a marking station to a nip formed by a first roll and a second roll, comprising:
- directing a leading edge of the sheet toward the nip at an angle which causes the sheet to form an arc between the marking station and the nip as the leading edge of the sheet enters the nip;
- and
- as a trailing edge of the sheet substantially exits the marking station, straightening the sheet between the marking station and the nip.
A printing apparatus, comprising:
- a marking station;
- a nip, formed by a first roll and a second roll;
- means for directing a leading edge of a sheet toward the nip at an angle which causes the sheet to form an arc between the marking station and the nip as the leading edge of the sheet enters the nip;
- and
- means for straightening the sheet between the marking station and the nip as a trailing edge of the sheet substantially exits the marking station.
