Print head hydration system
View Patent ↗A printer is disclosed. The printer includes an ink jet print head having a plurality of nozzles to mark a printable recording medium with ink and an ink system to provide ink to the nozzles. The ink system includes a print head capping system to cap the nozzles whenever the nozzles are not in use and a hydration system to supply a hydration fluid to the print head capping system to provide moisture to the ink at the nozzles while the nozzles are capped.
1. A printer comprising:
an ink jet print head having a plurality of nozzles to mark a printable recording medium with ink; and
an ink system to provide ink to the nozzles; including:
a print head capping system to cap the nozzles whenever the nozzles are not in use; and
a hydration system to supply a hydration fluid to the print head capping system to provide moisture to the ink at the nozzles while the nozzles are capped, including:
a fluid source;
a first fluid regulating device;
a fluid distribution system;
a second fluid regulating device;
a second fluid distribution system;
a first sensor to detect a fluid in a capping system; and
a controller to activate the first fluid regulating device to supply the fluid from the fluid source to the fluid distribution system and ink at print head nozzles upon the controller determining that hydrating is to be performed and activates the second fluid regulating device and the second fluid distribution system to supply fluid from the fluid source to ink removal lines to prevent clogging of the ink removal lines.
2. The printer of claim 1 , wherein the controller regulates ink hydration fluid from the hydration system to the capping system and to ink at the print head nozzles.
3. The printer of claim 2 , wherein the hydration system further comprises a first timer monitored by the controller to determine an appropriate time for the hydrating cycle.
4. The printer of claim 2 , wherein the capping system comprises:
a cap;
a maintenance station coupled to the cap; and
a plurality of ink removal lines coupled to the maintenance station.
5. The printer of claim 4 , wherein the controller initiates fluid delivery into the ink removal lines to prevent ink from clogging the ink lines.
6. The printer of claim 1 , wherein the controller deactivates the first fluid regulating device and the fluid distribution system upon determining that hydrating should not continue.
7. The printer of claim 1 , wherein the hydration system further comprises a second timer monitored by the controller to determine the fluid level remaining in the fluid source.
8. The printer of claim 1 , wherein the fluid includes water.
9. A method comprising:
monitoring a fluid detection system within an inkjet printer;
determining when hydration fluid may be provided to a print head capping system; and
supplying a hydration fluid from a hydration system to the capping system to provide moisture to ink at print head nozzles while the nozzles are capped by:
a controller activating a first fluid regulating device to supply the fluid from a fluid source to a fluid distribution system and to the ink at the nozzles upon the controller determining that hydrating is to be performed; and
activating a second fluid regulating device to supply fluid from the fluid source to ink removal lines to prevent clogging of the ink removal lines.
10. The method of claim 9 , wherein monitoring the fluid detection system comprises the controller monitoring a sensor that measures the fluid within the capping system.
11. The method of claim 10 , wherein monitoring the fluid detection system comprises the controller monitoring a timer that is used to trigger the hydration system at a predetermined interval.
12. The method of claim 9 , wherein supplying the hydration fluid into the one or more ink lines comprises the controller activating the second fluid regulating device and a fluid distribution system to supply a purge of fluid from a fluid source to ink removal lines.
13. A print head hydration system, comprising:
a fluid source;
a first fluid regulating device;
a fluid distribution system;
a second fluid regulating device;
a second fluid distribution system;
a first sensor to detect a fluid in a capping system; and
a controller to activate the first fluid regulating device to supply the fluid from the fluid source to the fluid distribution system and ink at print head nozzles upon the controller determining that hydrating is to be performed and activates the second fluid regulating device and the second fluid distribution system to supply fluid from the fluid source to ink removal lines to prevent clogging of the ink removal lines.
14. The print head hydration system of claim 13 , wherein the controller deactivates the first fluid regulating device and the fluid distribution system upon determining that hydrating is to be discontinued.
15. The print head hydration system of claim 13 , further comprising a second sensor monitored by the controller to determine the fluid level remaining in the fluid source.
