The present invention is a method and apparatus for vacuuming toner waste from a toner sump in a xerographic printing machine. A xerographic module in the machine contains a photoconductor, charging devices, a cleaning unit and the toner sump. When the toner sump approaches a full condition, the toner waste must be removed in order to prevent failure of the xerographic module seals. This is accomplished by removing the xerographic module from the machine, opening a sealed toner sump port and attaching a vacuum source to the toner sump port so that the toner waste can be removed with the vacuum source. A disposal adaptor tool sealingly engages the vacuum source to the toner sump at the toner sump port, allowing the toner to removed in a clean glove environment. Once the toner waste is removed from the toner sump, a new toner seal is placed over the toner sump port and the xerographic module is returned to the machine for further use.
