Abstract

A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruct the immiscible fluid applicator to apply immiscible fluid onto the surface of the printhead to cap the number of nozzles. A printer subassembly may comprise an immiscible fluid applicator to wipe a layer of immiscible fluid onto a surface of a printhead. A printer may comprise a page wide array printhead, an immiscible fluid applicator to wipe a layer of immiscible fluid over a printhead to cap nozzles over the width of the printhead, and a controller to instruct the printhead to print after the layer of immiscible fluid has been applied over the printhead so that ink ejects through the immiscible fluid while non-used nozzles remain capped by the immiscible fluid layer.

Claims (22)

1. A printer comprising:

a printhead comprising a number of nozzles;

an immiscible fluid applicator; and

a processor to instruct the immiscible fluid applicator to apply immiscible fluid to the surface of the printhead to cap the number of nozzles.

2. The printer of claim 1 , in which the immiscible fluid applicator comprises a wick.

3. The printer of claim 2 , in which the wick is to supply an amount of immiscible fluid to a wiper and in which the wiper is to wipe the amount of immiscible fluid onto the surface of the printhead.

4. The printer of claim 2 , in which the immiscible fluid applicator further comprises a wiper to wipe the printhead after immiscible fluid has been applied to the printhead by the wick to leave an amount of immiscible fluid on the printhead.

5. The printer of claim 1 , in which the immiscible fluid applicator comprises a roller to supply an amount of immiscible fluid to the surface of the printhead.

6. The printer of claim 5 , in which the immiscible fluid applicator further comprises an immiscible fluid supply to supply an amount of immiscible fluid to the roller.

7. The printer of claim 5 , in which the immiscible fluid applicator further comprises a wick to supply an amount of immiscible fluid to the roller.

8. The printer of claim 1 , in which the immiscible fluid applicator comprises a wiper comprising an immiscible fluid channel in which the wiper wipes across the surface of the printhead while the immiscible fluid channel in the wiper ejects an amount of immiscible fluid.

9. The printer of claim 1 , in which the immiscible fluid applicator comprises a porous web-wipe to apply an amount of immiscible fluid onto the surface of the printhead.

10. The printer of claim 9 , in which the immiscible fluid applicator further comprises a blade to squeegee an amount of immiscible fluid from the web-wipe and onto the surface of the printhead.

11. A printer comprising:

a printhead;

an immiscible fluid applicator to wipe a layer of immiscible fluid over a printhead to cap nozzles over the width of the printhead; and

a controller to instruct the printhead to print after the layer of immiscible fluid has been applied over the printhead so that ink ejects through the immiscible fluid while non-used nozzles remain capped by the immiscible fluid layer.

12. The printer of claim 11 , wherein the immiscible fluid comprises isoparaffin.

13. The printer of claim 11 , wherein the printhead comprises a cartridge with a memory chip providing data when the immiscible fluid layer will be applied.

14. The printer of claim 11 , wherein a surface tension of the immiscible fluid is sufficient high that, after ink has been ejected through the immiscible fluid, the immiscible fluid reseals and covers a nozzle from which ink was ejected.

15. The printer of claim 11 , wherein a thickness of the layer of immiscible fluid is 1 mm or less.

16. The printer of claim 11 , wherein the applicator comprises a textile wipe.
