(54)	Image production device vacuum cleaner

(57) An electrophotographic reproduction device includes an air blower (15) having a vacuum pressure inlet (14) and a positive pressure outlet (16). The inlet and/or outlet is connected to provide blower induced airflow at device stations, such as a sheet detack station (11), that require blower induced airflow for proper operation thereof. The duct or conduit (13) that connects to the blower inlet may be attached to a flexible vacuum cleaner hose (22) by service personnel. The vacuum cleaner hose (22) is then manually usable to clean the interior of the device of the buildup of toner, paper dust and debris, as the device is periodically serviced.
