Abstract:
An aqueous-based inkjet ink for a thermal inkjet printhead includes: a pigment; 2 to 90 ppm ammonium ions; and an ink vehicle. The ink has a pH in the range of 8 to 9.5 and exhibits improved lifetime in thermal inkjet printheads with minimal loss of print quality.
Abstract:
An inkjet ink for improving printhead lifetimes includes: an aqueous-based ink vehicle; a colorant; an anti-kogation additive; and an anti-corrosion additive having at least one acetylenic group, the acetylenic group being absent any tertiary or quaternary α-carbon atoms.

Abstract:
A printer includes: an inkjet printhead assembly; a sled slidably arranged with respect to the printhead assembly, the sled supporting a platen module, a capper module and a wiper module; a sliding mechanism for sliding the sled relative to printhead assembly so as to selectively align one of the platen, capper and wiper modules with the printhead assembly; and a lift mechanism for lifting an aligned module linearly away from the sled and towards the printhead assembly. The platen module is positioned between the capper and wiper modules on the sled, such that the capper and wiper modules are positioned at opposite sides of the printhead assembly during printing.

Abstract:
A method of inhibiting evaporation of water from inkjet nozzles of a printhead. The method includes the steps of: providing a wiping material infused with a liquid composition comprising an evaporation inhibitor; and wiping the wiping material over a nozzle plate of the printhead. The evaporation inhibitor is transferred to the nozzle plate during wiping and thereby inhibits evaporation of water from the inkjet nozzles.
