Abstract
A printing fluid delivery method is disclosed for a jet printer. The method involves displacing printing fluid in a printing fluid delivery chamber in a printing fluid delivery system by a predetermined amount. After the step of displacing, printing fluid can be driven out of the chamber at a constant flow rate.
Claims35
A printing fluid delivery method for a jet printer, comprising:
- displacing printing fluid in a printing fluid delivery chamber in a printing fluid delivery system by a predetermined amount, and
- driving printing fluid out of the chamber at a constant flow rate after the step of displacing.
A printing fluid delivery system for a jet printer, comprising:
- a printing fluid delivery chamber,
- an actuation system operative to displace printing fluid in the chamber, and
- a controller including logic operative to cause the actuation system to move by a predetermined amount at a first rate and to then drive the actuation system at a second, predetermined rate that is lower than the first rate.
A printing fluid delivery system for a jet printer, comprising:
- means for displacing printing fluid in a printing fluid delivery chamber in a printing fluid delivery system by a predetermined amount, and
- means for driving printing fluid out of the chamber at a constant flow rate after displacement by the means for displacing.
A printing fluid delivery method for a jet printer, comprising:
- monitoring a printing fluid flow rate of printing fluid at a nozzle, and
- adjusting a displacement rate of the printing fluid based on the step of monitoring.
A printing fluid delivery system for a jet printer, comprising:
- a printing fluid delivery nozzle,
- a flow measurement sensor responsive to printing fluid flow at the printing fluid delivery nozzle,
- a printing fluid supply actuator operative to adjust printing fluid flow at the printing fluid delivery nozzle, and
- a controller responsive to the flow measurement sensor and having a control output provided to the actuator.
A printing fluid delivery method for a jet printer, comprising:
- means for monitoring a printing fluid flow rate of printing fluid at a nozzle, and
- means, responsive to the means for monitoring, for adjusting a displacement rate of the printing fluid.
