摘要：In one form of the invention, one sensor determines mutual alignment of pens;a second sensor measures color of dots formed on a print medium by the pens. Another
form has two carriages—one moving pens to mark on a medium and the second used torefine quality of images produced. In a third form, a sensor measures color of testpatterns by one or more pens; a hood—generally around the sensor laterally relative toa sensing direction—excludes ambient light from the sensor during measuring; amechanism advances the hood along the sensing direction toward the patterns. In afourth form, a pen ejects multiple liquid-ink drops onto a medium, and a sensor
infrequently measures color of resulting dots—only when the pen is not forming images.In addition to these four forms of the invention, three others are detailed in the text.
