Abstract
A copier/printer having a transfer station for transferring images from an imaging member to copy sheets includes the improvement of removing debris from within the copier/printer by locating baffles and vacuum ports within the copier/printer to cause deposition, collection and removal of debris and other contaminants in specified locations. An electrical bias is selectively applied to at least some of the baffles to electrostatically attract the contaminants thereon. The vacuum ports are connected to a vacuum source that could operate continuously or intermittently at start-up or shutdown.
Claims16
In a copier/printer having a transfer station for transferring images from an imaging member to copy sheets, the improvement of removing contaminants from predetermined locations within the copier/printer including the paper path before the copy sheets reach a transfer station of the copier/printer, characterized by:
- a plurality of selectively biased baffle means placed at said predetermined locations for collecting contaminants electrostatically thereon;
- and contaminant removal means for removing contaminants from said baffle means.
In a printer apparatus having a transfer station for transferring images from a imaging member to copy sheets, the improvement of removing copy sheet debris before the copy sheets reach the transfer station and removing other contaminants from the environment of the printer apparatus, characterized by:
- a plurality of selectively biased baffle means positioned at different locations within the printer to attract debris and other contaminants, and vacuum pick-up means placed at said plurality of baffle means locations, said vacuum pick-up means being adapted to be actuated at predetermined times to remove debris from said baffle means.
In a printer apparatus having a plurality of component stations for transferring images from a imaging member to copy sheets, the improvement of removing contaminants from the environment of the printer apparatus, characterized by:
- a plurality of selectively biased baffle means positioned at different locations within the printer to attract debris and other contaminants, and vacuum pick-up means placed at said plurality of baffle means locations, said vacuum pick-up means being adapted to be actuated at predetermined times to remove debris from said baffle means.
