This disclosure describes a system and method for documenting and/or quantifying the inspection of the cleanliness of a surface. The documenting is attained through the capture of an image of the surface and uploading said image along with metadata about the image to a place of secure storage such as a company internal server or a web server. The quantification is attained through image analysis of the image, with or without enhancements such as UV light, to derive a value for the amount of residue remaining on the surface. This quantification can be performed on a device and sent to a server, or performed on the server itself after the image has been sent. In all cases, the inspection of cleanliness is documented with or without quantification.

System and method for validating cleanliness of a surface

Described herein is a method and apparatus for driving a drop ejection device to produce drops having straight trajectories. In one embodiment, a method for driving a drop ejection device having an actuator includes building a drop of a fluid with at least one drive pulse by applying a multi-pulse waveform having the at least one drive pulse and a straightening pulse to the actuator. Next, the method includes causing the drop ejection device to eject the drop with a straight trajectory in response to the pulses of the multi-pulse waveform. The straightening pulse is designed to ensure that the drop is ejected without a drop trajectory error.
