Abstract

Example implementations relate to print substance container vibration. A vibrator for a print system may comprise a motor, and a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container. The vibration may be caused in response to the rotation of an eccentrically loaded weight about a central axis of the vibrator.

First claim

What is claimed:

1. A vibrator for a print system comprising:
a motor activated by a print system communication source;
an eccentrically loaded weight; and
a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container, wherein the vibration is caused in response to rotation of the eccentrically loaded weight about a central axis of the vibrator.

2. The vibrator of claim 1 , wherein the motor is activated by an electromechanical switch in communication with the print system communication source.

3. The vibrator of claim 2 , wherein the motor and the vibration shaft are placed inside the print substance container.

4. The vibrator of claim 2 , wherein the motor and the vibration shaft are coupled outside the print substance container.

5. The vibrator of claim 2 , further comprising a plurality of vibration shafts arranged around the central axis of the vibrator.

6. The vibrator of claim 2 , wherein the motor and the vibration shafts are constructed from composite materials.

7. The vibrator of claim 1 , wherein the motor is activated by the print system communication source in communication with an electromechanical switch.

8. The vibrator of claim 7 , wherein the motor and the vibration shaft are placed inside the print substance container.

9. The vibrator of claim 1 , wherein the motor and the vibration shaft are placed inside the print substance container.

10. The vibrator of claim 1 , wherein the motor and the vibration shaft are coupled outside the print substance container.

11. The vibrator of claim 1 , further comprising a plurality of vibration shafts arranged around the central axis of the vibrator.

12. The vibrator of claim 1 , wherein the motor and the vibration shafts are constructed from composite materials.

13. A method comprising:
receiving, by a print system communication source of a print system, an input that a print substance container of the print system has entered a mode indicating print substance is inaccessible;
activating a plurality of vibrators, coupled to the print substance container by activating an electromechanical switch, wherein the activation is based on a programmable frequency, a duration of vibration, and combinations thereof;
generating vibration of the plurality of vibrators;
redistributing print substance of the print substance container in response to the vibration of the plurality of vibrators; and
releasing print substance from the inaccessible areas of the print substance container to a development area to use the print substance to print via the print system.

14. The method of claim 13 , further comprising the plurality of vibrators causing vibrations by rotating an eccentrically loaded weight about a central axis of the plurality of vibrators.

15. The method of claim 13 , further comprising activating the electromechanical switch by activating a power supply source of the print system.

16. A print system comprising:
a print substance container;
a plurality of vibrators coupled to the print substance container to:
determine the print substance container has entered an inaccessible substance mode;
activate the plurality of vibrators by activating an electromechanical switch causing vibration by an electric pulse to force a weight to displace and return to the weight's initial position;
redistribute print substance of the print substance container; and
release print substance in the inaccessible areas of the print substance container to print via the print system.

17. The print system of claim 16 , wherein the print substance container enters the inaccessible substance mode as print substance volume reaches a lower than average threshold.

18. The print system of claim 16 , wherein the print substance container enters the inaccessible responsive mode as the print substance container is in use for a threshold time duration.

19. The print system of claim 16 , wherein the print substance container receives print substance via a plurality of ink reservoirs from different locations within the print system.

20. The print system of claim 16 , wherein the electromechanical switch is activated by a print system communication source, wherein the activation is based on a programmable frequency, a duration of vibration, and combinations thereof.
