Abstract:
A sheet transport roller system and methods for reducing sheet skew using a sheet transport roller system are disclosed. A sheet transport roller system for use in a document processing device may include a plurality of idler rollers, a plurality of drive rollers and a load distribution mechanism. Each drive roller may correspond to a corresponding idler roller. The load distribution mechanism may be configured to support the plurality of idler rollers and to equalize normal forces applied by each idler roller towards the corresponding drive roller. The load distribution mechanism may include a center loading spring in contact with the document processing device.
