摘要：
An inkjet printing system provides an on/off valve adapted for periodic engagement with an inlet port on a print cartridge mounted in a carriage. The valve is connected to an ink supply which is located off the carriage. As the ink reservoir in the print cartridge is slowly depleted during operation of the printing system, a mechanism periodically moves the valve from a first passive position separated from the print cartridge to a second active position engaged with the inlet port of the print cartridge in order to allow replenishment of the ink reservoir in the print cartridge without removing the print cartridge from the carriage.
