Abstract
A pressure regulation system for a high throughput inkjet printer uses a peristaltic pump to provide a meniscus vacuum to the printheads. A peristaltic pump is a small and inexpensive device which can produce a low flow rate suitable for achieving the relatively small meniscus vacuum required by drop on demand systems. Furthermore the pump can operate in both directions, and seals in the event of power loss.
