Abstract
In order that sensitive structures of inkjet printing mechanisms be cleaned without damaging these structures, a cleaning sheet and a process of using the sheet has been created. Debris and dried ink is removed from print cartridges and their carriage using a cleaning sheet having two strips of material spaced with a napped surface disposed longitudinally between the side edges and spaced apart from each other. By controlling the distance the strips are spaced from the sheet feed edge of the cleaning sheet, the print cartridges can be placed adjacent the strips for scrubbing against the strips without resulting in a media jam in the printer due to the increased thickness of the cleaning sheet.
