20100295893 | Ink-Jet Recording Apparatus - An ink-jet recording apparatus includes a rubber member in an ink flow passage. The rubber member is made of a rubber composition including a rubber base polymer selected from ethylene-propylene diene rubber polymer and isobutylene-isoprene rubber polymer, and at least one trapping agent selected from calcium carbonate, silicon dioxide, talc, and clay. The trapping agent is effective for absorb-trapping various types of additives that may be present in the rubber member. The additives in the rubber are thereby held in the rubber structure and prevented from being eluted into the water-based ink or the preservative solution, which can lead to clogging of ink nozzles and the like. | 2010-11-25 |
20100295894 | INKJET PRINTER HAVING ROTATABLE SERVICING MEMBER - An inkjet printer includes an inkjet printhead and a servicing assembly. The servicing assembly includes a rotatable elongate servicing member arranged to rotate about an axis parallel to a longitudinal axis of the printhead. The rotatable elongate servicing member integrally comprises a plurality of radially disposed elongate working surfaces which rotate with the servicing member to service the printhead. One of the working surfaces comprises a blotting material. | 2010-11-25 |
20100295895 | INKJET RECORDING DEVICE - An inkjet recording device is provided, which includes a recording head, a cleaning unit and a wiper cap member. The recording head includes a nozzle face on which an ink-injecting nozzle is formed. The cleaning unit includes a wiper case and a wiper member. The wiper case has a wiper accommodating portion and a wiper opening. The wiper member is configured to be accommodated in the wiper accommodating portion, protrude out of the wiper accommodating portion via the wiper opening and move relatively to the recording head to clean the recording head. The wiper cap member shuts the wiper opening of the wiper case. | 2010-11-25 |
20100295896 | PRINTABLE SUBSTRATE AND NOZZLE ALIGNMENT SYSTEM - According to the present disclosure, a printer apparatus may include a chuck configured to support a substrate thereon, a rail spaced apart from the chuck, a printhead carriage frame coupled to the rail and containing a printhead carriage housing at least one printhead therein, a first camera assembly configured to capture image data of the printhead and provide the image data to a computer, and a computer receiving the image data from the first camera assembly and configured to determine a deviation between a desired position of the printhead and an actual position of the printhead. | 2010-11-25 |
