Method and cover for cleaning a print head
A cover for covering the nozzle plate of a print head while in a parking position to delay a drying of ink. The cover can clean the nozzle plate while the nozzle plate is covered. A cost-effective and installation space-efficient cleaning of the nozzle plate of a print head is thus enabled.
1. A cover for covering a nozzle plate of a print head of an inkjet printer, comprising:
a container configured to house a climate control fluid, the container including an opening that is configured:
to receive the climate control fluid into an interior of the container to generate a microclimate for the nozzle plate to delay a drying of ink in the print head in comparison to an instance in which the nozzle plate is exposed to an ambient air of the printer, the climate control fluid being different than the ink in the print head;
to receive the nozzle plate directed into the container via the opening to cover the nozzle plate by the container; and
such that the nozzle plate seals the opening of the container in a fluid-tight manner while the nozzle plate is arranged in the opening of the container; and
a wiper configured to be directed past the nozzle plate of a print head while the nozzle plate is arranged in the opening of the container to wipe ink off the nozzle plate and into the container.
2. The cover according to claim 1 , further comprising:
at least one guide rail; and
a wiper mount to which the wiper is fixed, the wiper mount being configured to travel along the guide rail and past the nozzle plate within the container.
3. The cover according to claim 2 , wherein the container comprises a drain via which the climate control fluid may be drained out of the interior of the container.
4. The cover according to claim 3 , wherein the container comprises an inlet via which the climate control fluid may be provided into the interior of the container.
5. The cover according to claim 2 , wherein the container comprises an inlet via which the climate control fluid may be provided into the interior of the container.
6. The cover according to claim 2 , wherein:
the container is configured to be pivoted toward the print head or away from the print head about a rotation axle; and
the container of the cover includes a wall segment to one side of the opening that is configured to form a basin configured to receive the climate control fluid when the container is pivoted away from the print head.
7. The cover according to claim 1 , further comprising an applicator that is configured to apply cleaning fluid to the nozzle plate to clean the nozzle plate while the nozzle plate is covered.
8. The cover according to claim 1 , wherein the climate control fluid is a cleaning fluid.
9. The cover according to claim 1 , wherein the container comprises a drain via which at least a portion of the climate control fluid and the ink wiped off the nozzle plate may be drained out of the interior of the container.
10. The cover according to claim 1 , further comprising an applicator configured to apply a portion of the climate control fluid to the nozzle plate to clean the nozzle plate while the nozzle plate is covered.
11. The cover according to claim 10 , wherein the wiper is configured to wipe off at least some of the climate control fluid applied to the nozzle plate and the ink on the nozzle plate from the nozzle plate and into the container.
12. The cover according to claim 10 , wherein the climate control fluid is a cleaning fluid.
13. An inkjet printer, comprising:
a print head having a nozzle plate with at least one nozzle configured to eject ink droplets onto a recording medium to print a print image onto the recording medium in a first mode of operation;
a cover configured to cover and simultaneously clean the nozzle plate of the print head in a second mode of operation, the cover including:
a container configured to house a climate control fluid, the container including an opening that is configured:
to receive the climate control fluid into an interior of the container to generate a microclimate for the nozzle plate to delay a drying of ink in the print head in comparison to an instance in which the nozzle plate is exposed to an ambient air of the printer, the climate control fluid being different than the ink in the print head;
to receive the nozzle plate directed into the container via the opening to cover the nozzle plate by the container; and
such that the nozzle plate seals the opening of the container in a fluid-tight manner while the nozzle plate is arranged in the opening of the container; and
a wiper configured to be directed past the nozzle plate of a print head while the nozzle plate is arranged in the opening of the container to wipe ink off the nozzle plate and into the container.
