  • Publication number: 20220146544
    Abstract: Aspects of the present disclosure relate to evaporation compensation in fluidic devices. An example apparatus for evaporation compensation includes an assessment circuit to determine an amount of evaporation of a volume dispensed in a microwell of a fluidic device. The amount of evaporation may be determined based on the volume in the microwell, and an amount of time after dispensing the volume in the microwell. A compensation circuit may determine, based on the amount of evaporation, a compensation factor for the microwell including an amount of a normalizing fluid to compensate for the amount of evaporation. The compensation circuit may also create a normalization profile for the fluidic device, including an association between the fluidic device and the compensation factor. A dispensing circuit may dispense the normalizing fluid in the microwell according to the normalization profile.

  • Publication number: 20220147711
    Abstract: Example techniques for processing service notes are described. In an example, labeled service notes, associated with fuser units of a plurality of image rendering devices, are processed to generate a vector corresponding to each of the labeled service notes, a labeled service note comprising natural language text describing an error event and a corresponding service activity associated with a fuser unit, wherein the labeled service note is assigned a label based on a category of failure of the fuser unit. Based on the processing, a relationship between vectors and labels corresponding to the labeled service notes is generated.

  • Publication number: 20220143915
    Abstract: Object model data modification is described in which object model data defining a first object to be generated by a three-dimensional printer may be obtained. A determination whether the first object is an object that may be adversely affected by a post-processing apparatus during post-processing based on a geometry of the first object to be generated can be made; and if the determination is affirmative, the object model data may be modified by adding a structure to the object model data to create a modified object comprising the first object and the structure, the modified object of a different geometry to the first object so as not to be adversely affected by the post-processing apparatus during the post-processing.
