Abstract: A set of ink sticks includes multiple ink sticks, each adapted to be inserted in an insertion direction into one of the feed channels of a phase change ink jet printer. Each ink stick has a keyed surface substantially aligned with the insertion direction, and each of the keyed surfaces has a key feature having a position relative to the keyed surface that corresponds to the position of the feed channel relative to an aspect of the printer. A method of inserting an ink stick into the delivery system of a phase change ink jet printer includes orienting the ink stick with a keyed surface facing a particular direction and identifying the position of the key feature relative to the remainder of the keyed surface. An ink feed channel of the feed system having a coinciding position in the ink delivery system is identified, and the ink stick is inserted into the identified ink feed channel.

Abstract: An electronic portable document format (PDF) file contains different combinations of gradient blends between spot color and process color. Each gradient blend is represented as both rasterized bitmap and vector images. The rasterized bitmap and vector images can be used to quickly assess the capability of any digital front end (DFE) to process the color gradient blends. The PDF file contains two sets of spot color and process color blended combinations. The first set contains four types of color gradient blends: spot-to-spot, process-to-spot, spot-to-process, and process-to-process, each of which represent the intended design. The second set contains the same four types of color gradient blends, except here the CMYK colors associated with the spot colors are intentionally manipulated. By printing the PDF file using different DFEs, one may compare the output from the two sets and immediately identify any color gradient handling problem, providing a quick benchmarking tool.

The outflow port from which a developer flows out is formed in the container main body storing the developer. The open/closed member is supported to the container main body and, moves relative to the container main body based on a rotation of the container main body. The open/closed member opens and closes the outflow port. The turn stop part is formed on a wall face of the container main body, and has a circular arc shape being concentric with a rotation direction of the container main body. The turn stop part engages with a convex part which is provided in the attachment section and is formed at a different position in response to the image forming apparatus body.
