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.
