Abstract
An ink reservoir, for supplying ink to at least one inkjet print head, containing partitions which divide the volume of ink in the reservoir into sub-volumes, which significantly reduce, or eliminate, pressure fluctuations which arise as a result of acceleration of the ink reservoir. Each sub-volume is connected to adjacent sub-volumes via pressure equilibration passages. Lower pressure equilibration passages ensure equal ink height within all sub-volumes, following the discharge of ink from supply outlets and upper pressure equilibration passages ensure equal air pressure above all sub-volumes. A further as aspect involves a reservoir supplying print heads where planes, substantially perpendicular to the primary direction of motion, intersect corresponding reservoir supply outlets and print head supply inlets in order to eliminate supply line pressure fluctuations. A combination of the two aspects eliminate both reservoir and supply line pressure fluctuations.
