Abstract
An inkjet printer having an expandable ink container biased to expand and configured to receive refill ink and an ink reservoir to provide refill ink to the expandable ink container. The printer also has an electronic volume detector to detect a refill value and a full value of the volume of the expandable ink container. The flow of refill ink begins when the volume of the expandable ink container decreases to the refill value and ceases when the volume of the expandable ink container increases to the full value.
