Abstract: In one example of the disclosure, a first measurement of actual quantity of ink in a target cartridge is taken utilizing a scale. An incremental dosage quantity be deposited into the target cartridge in a dosing pass is determined based upon a desired quantity, the actual quantity, and an undershoot safety factor. A valve is opened to enable a pressure deposit of the incremental dosage quantity of ink to the target cartridge, and then closed. A residue cutter is utilized to scrape the valve and thereby make a scraper deposit of ink to the target cartridge. A second measurement of actual quantity of ink in the target cartridge is taken utilizing the scale. An additional dosage pass is performed if the second measurement is not within an accepted variance of the desired quantity. The making of dosing passes is discontinued if the second measurement is within the accepted variance.

Abstract: In one example, a sheet media alignment system includes: a guide (12) defining a curved media path (14) that extends from an upstream part of the guide to a downstream part of the guide; a movable blocker (16, 56) to block the curved media path (14) at the downstream part of the guide, the blocker movable into and out of a blocking position in which the blocker is spaced from the downstream part of the guide a first distance; and a driver (24, 58) upstream from the curved media path to drive a media sheet into the guide along the curved media path and into the blocker. The driver is spaced from the upstream part of the guide a second distance greater than the first distance such that a media sheet driven into the blocker will buckle between the driver and the guide before it will buckle between the guide and the blocker.

Abstract: The present disclosure provides a method and system for delivering a high- viscosity fluid 300. In an example, a reciprocating a piston pumps a high-viscosity fluid 300 through a one-way check valve 130 into a pump chamber 125. Responsive to receipt of a request for a dose of the high-viscosity fluid 300, an output valve 135 in the pump chamber 125 is opened, and the piston is reciprocated in order to eject a dose of the high-viscosity fluid 300 from the pump chamber 125 through the output valve 135.
