摘要： A method of maintaining a printhead comprises the steps of: (i) providing a maintenance roller having a contact surface for sealing engagement with the printhead; (ii) moving the roller into a first position in which the contact surface is sealingly engaged with the printhead; (iii) moving the roller into a second position in which the contact surface is disengaged from said printhead; and (iv) rotating the roller such that the contact surface is conveyed away from the printhead. The maintenance roller does not rotate when the contact surface is sealingly engaged with the printhead.

摘要： An inkjet printer includes a printhead for printing onto a media substrate, the printhead defining a plurality of nozzles from which ink is expelled; an ink tank provided upstream of the printhead; a sump provided downstream of the printhead for collecting unused ink from the printhead, the sump having a lower portion for holding the unused ink and an upper portion defining a headspace of air above the unused ink; a first fluid conduit extending between the printhead and the sump for communicating the unused ink from the printhead to the sump, the first fluid conduit connecting the sump to a position in the printhead upstream of the plurality of nozzles; and a pump connected to the sump, the pump for drawing air from the headspace of the sump into atmosphere and effecting a negative pressure in the printhead upstream of the nozzles. Communication of ink from the ink tank to the printhead is effected by the negative pressure generated by the drawing of air from the headspace of the sump.

摘要： An inkjet printer has an inkjet printhead and an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to the printhead. The regulator includes a bubble outlet positioned in a headspace of an ink chamber for bubbling air bubbles directly into the headspace at all operative ink levels. A capillary channel supplies ink from the chamber to the bubble outlet by capillary action and an air channel connects an air inlet with the bubble outlet. The bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into the ink chamber as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.

摘要： An ink cartridge suitable for regulating a hydrostatic pressure of ink supplied to an inkjet printhead is provided. The cartridge comprises an ink chamber having an ink outlet for fluid communication with the printhead via an ink line; an air inlet open to atmosphere; a bubble outlet for bubbling air bubbles into the chamber, each air bubble comprising an air cavity trapped inside a film or a body of ink; and an air channel connecting the air inlet and the bubble outlet. The bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into the chamber as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.
