A cleaning cartridge insert is provided for removing residual paper debris and toner from a laser printer in between printer cartridge removal and replacement. The cartridge comprises a modified laser printer cartridge with an internal cavity lined with an adhesive foam tape, a plurality of air inlet tubes and a drive roller having an adhesive outer surface. With the lid of the printer cartridge loading cavity is in an open state, the cartridge is placed therein into a working position, as would a replacement cartridge. Compressed air is then forced into the nozzles of the air inlet tubes, stirring paper dust, residual toner and debris from the interior of the printer and onto the foam tape adhesive within the cavity of the cartridge device. The lid is then closed, which initiates the drive roller for cleaning debris from the bias transfer roller via rotation during the machine initializing stage. The present invention is intended as a preventative maintenance device for laser printers, prolonging their useful life and the increasing service intervals wherein a specialist is required for maintenance and cleaning.
