摘要： A sealed reservoir of an ink cartridge of an ink jet printer has one or two spring-loaded bags therein functioning as an accumulator to control back pressure within the sealed reservoir. A source of ambient air for the bag or bags also serves as a source of the air for an air bubble generator. The interior of the single bag or one of the two bags communicates with the air bubble generator so that air is supplied to the air bubble generator when air bubbles are required within the sealed reservoir to decrease back pressure therein. This same air flow arrangement from the interior of the single bag or one of the two bags permits the interior of the bag to receive ink leaking from the sealed reservoir passing through at least one capillary channel of the air bubble generator when the back pressure within the sealed reservoir becomes too low.
