An example system may include a processor and a non-transitory machine-readable storage medium storing instructions executable by the processor to determine, during an imaging operation by an imaging component of a printing device, whether a print queue, supplied by the imaging component, will be depleted by a printing component of the printing device prior to a completion of the imaging operation; and adjust, based on the determination, a media feed rate of the printing component.

Media feed rate adjustments

Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to form an image on a print medium, a memory resource, and a controller to receive a print job to form the markings on the print medium, designate a pixel of the received print job to form a covert dot pattern on the markings, where the pixel corresponds to a first laser intensity level; and adjust a laser intensity of the printing device to a second laser intensity level based on the first laser intensity level of the designated pixel to form the covert dot pattern.

Covert marking

A method for calibrating a multi-function printing (MFP) device includes printing a calibration target image on a first side of a print medium from at least one print medium source with a printing device of the MFP device. The calibration target image includes at least one fiducial. The method includes scanning the first side of the print medium comprising the calibration target image with a scanning device of the MFP device to create a first scanned image, identifying at least one edge of the print medium via a background pattern to determine a number of scan measurements, identifying at least one position of the at least one fiducial within the calibration target image, and calculating a calibration target error based on the at least one fiducial and the scan measurements.

Multi-function printing (MFP) device calibration

In one embodiment, an article includes a spacer configured to increase a dimension of only a portion of a guide part on a print cartridge when the spacer is fastened to the guide part and a fastener allowing the spacer to be removably fastened to the guide part.
