ABSTRACT:
An idler roller assembly that prevents jams and image deletion in copier/printers by removing any corrugation in sheets before they reach sharp turns includes a shaft onto which idler rollers are mounted with the shaft having a bend in the middle in order to provide a "toe out" condition to steer out any existing sheet corrugation. An alignment member is attachable to the shaft in order to prevent mis-installation of the shaft in its mounting support.
