    摘要： In an example, a method includes rotating a print apparatus component to be cleaned about a first rotational axis. A cleaning element having a cleaning surface in contact with the print apparatus component may be driven such that the cleaning surface has a component of motion which is parallel to the first rotational axis in a contact region. A relative velocity of the cleaning element and the print apparatus component may be varied during a cleaning operation.

    摘要： A print agent application assembly includes a print agent transfer roller to receive print agent and transfer a portion of the print agent to a photoconductive surface. The assembly may also include a print agent regulator roller to regulate a film thickness of print agent on the print agent transfer roller. The assembly may also include a mechanism to generate an oscillating force to be applied to print agent on the print agent transfer roller. A method and a print apparatus are also disclosed.

    摘要： In an example of the disclosure, a device (38) includes: an acquiring unit to obtain first reflectance output values acquired from reference samples (52) by a reference color measuring device and to obtain second reflectance output values acquired from the reference samples (52) by a second color measuring device (2); a processing unit to determine, for a plurality of wavelength values, correspondences between a first reflectance output value acquired by the reference color measuring device and a second reflectance output value acquired by the second color measuring device, and to perform, for each wavelength value, an interpolation based on the correspondences to obtain interpolation data; and a correcting unit to correct, based on the interpolation data, third reflectance output values acquired by the second color measuring device (2) from a sample of interest (12).

    摘要： A first separation distance is determined between a first pair of defects in a scanned image of a first printed sheet, and a second separation distance is determined between a second pair of defects in a scanned image of a second printed sheet. The defects are determined as having a separation distance in that the first and second separation distances are each within a first threshold of a specified separation distance and/or a difference between the first and second separation distances is below a second threshold. A source of the defects can be determined based on the characteristic separation distance.

    摘要： In an example, monitoring circuitry includes a first and second coupling, at least one of which is to capacitively couple the monitoring circuitry to a monitored circuit on a product packaging. The monitored circuit has a resistance which is indicative of a status of a product stored in the product packaging, and the monitored circuit is to be connected in series between the first coupling and the second coupling. The monitoring apparatus may determine the resistance of the monitored circuit via the first and second couplings.
