ABSTRACT:
In a clean room cups (70) are applied to the standpipe (28) of an unfilled inkjet cartridge. A sealing cup (80) is applied to the ink outlet (46, 48, 50) of the cartridge. Inert gas is forced back and forth between the cups and expelled into the clean room through a filter. Such cleaning removes particles, which significantly improves reliability of the filled cartridge.
