A printer includes a substrate support, a printhead assembly, first and second actuators, and a controller. The printhead assembly deposits material on a substrate supported on the substrate support. The first actuator is disposed at a side of the substrate support and coupled to a first linear track disposed along the side of the substrate support and oriented in a first direction. The second actuator is disposed at an end of the substrate support and coupled to a second linear track disposed along the end of the substrate support and oriented in a second direction perpendicular to the first direction. The first and second actuators are positioned to engage with the substrate simultaneously. The controller moves the first and second actuators together to rotate the substrate.

Printer, method of operating printer, and substrate handling mechanism

A drop placement analyzer for an inkjet printer is described herein. The drop placement analyzer comprises a film support that has an opaque, optically non-interfering vacuum surface for immobilizing a film against the optically non-interfering vacuum surface and photographing drops disposed on the film from the same side of the film on which the drops are disposed.

Drop placement analyzer for inkjet printing system

A substrate for an inkjet printer is described herein. The substrate comprises a material selected to provide high contrast reflected light and having a print material receiving surface with a neutral response to the print material.

Test substrate for inkjet printer drop placement analyzer

An inkjet printer is disclosed that has a substrate support; a calibration module disposed adjacent to the substrate support and comprising a stage member; and a print assembly disposed across the substrate support, the print assembly comprising a printhead and a calibration imaging device positionable to face the stage member.

Printer calibration module

An inkjet printing system with a droplet measurement apparatus is described herein. The droplet measurement apparatus has a light source with a collimating optical system, an imaging device disposed along an optical path of the collimating optical system, and a droplet illumination zone in the optical path of the collimating optical system, the droplet illumination zone having a varying droplet illumination location, wherein the light source, the imaging device, or both are adjustable to place a focal plane of the imaging device at the droplet illumination location. The droplet measurement apparatus is structured to accommodate at least a portion of a dispenser of the printing system within the droplet illumination zone.
