Abstract
A belt apparatus is provided for use in a document processing system having a baseplate, a removable bearing assembly connected to the baseplate and having a drive pulley to which a drive belt is drivingly coupled. The belt apparatus comprises a bracket coupled to the baseplate and for supporting the drive belt when the bearing assembly including the drive pulley is removed from the baseplate. The bracket supports the drive belt below the baseplate to allow the drive belt and the drive pulley of a replacement bearing assembly to be easily coupled together without having to lift the baseplate to gain access to the space below the baseplate. Preferably, the bracket comprises a substantially U-shaped bracket. The bracket may include a pair of flanges on which the drive belt rests when the bearing assembly is removed from the baseplate. The pair of flanges extend in substantially opposite directions relative to each other and substantially parallel with the plane in which the baseplate lies. The bracket supports the drive belt below the baseplate to allow the drive belt and the drive pulley of a replacement bearing assembly to be easily coupled together when the bearing assembly is removed from the baseplate and replaced with the replacement bearing assembly. The belt apparatus may include a belt tensioner mechanism for enabling the tension of the drive belt to be adjusted after the drive belt and the drive pulley of the replacement bearing assembly have been coupled together. The belt tensioner mechanism may include a torsion spring for enabling correct tension to be applied to the drive belt. The belt tensioner mechanism may include a belt tensioner handle accessible from above the baseplate for, when operated by a field-service operator, releasing tension from the drive belt to allow the bearing assembly to be more easily removed from the baseplate.
