Abstract: A two way roundness device can be configured as a device in which a tool, such as an indicator rotates or as a device in which the part to be measured or cut rotates. This ability to alternate between these two configurations is enabled by a combination of a rotating spindle assembly and a two-axis stage that can be oriented, in use, with the two-axis stage under the spindle assembly or with the two-axis stage on top of the spindle assembly.

Abstract: Inkjet printers are optimized for high printing throughput by dimensioning the media-carrying surface to have dimensions marginally larger than the size of one or more maximum-size standard print media sheets. The print media sheets used in conjunction with the media-carrying surface are selected from among standard sheets that exhibit certain geometrical properties and have sizes less than or equal to that of the maximum-size sheet. Drum-based and flatbed inkjet printers are provided with media-carrying surfaces dimensioned according to the invention.
