Abstract: An enlarged buckle chamber is positioned within an easily accessible, copy sheet transport path and used to compile sheets during fault cycle down in copiers/printers whenever sheets are prevented from reaching the output in sequence by jammed sheets. The user can then clear most jams by accessing the jam area plus the "easy to reach" area where internally purged sheet are gathered, thereby avoiding having paper distributed all over the paper path.

Abstract: A baffleless, easily accessible, copy sheet transport apparatus without sheet baffles that enables viewing and accessing jammed sheets without opening any baffles. The transport includes a pulley driven narrow timing belt with biased idler rolls providing normal force on belt driven copy sheets.

Abstract: An idler system that is both self-centering and self-aligning with a drive roll. The idler assembly consists of a pair of rolls connected by a shaft, the shaft being supported in a housing. The housing is retained by a resilient spring member which member allows the axis of rotation of the idler rolls to pivot in more than one plane simultaneously. This pivoting causes the axis of rotation of the idler assembly to align parallel with the drive roll axis. The single spring also provides an even loading of the normal force across the width of the drive nip. As a result of the alignment and even loading, skewing of a sheet is prevented as it is driven through the nip formed by the drive roll and the idler roll. The resilient spring mounting also allows for easy replaceability of the idler assembly and the housing is easily locatable between tabs formed in the frame of the machine for mounting the idler assembly therein.
