ABSTRACT:
A universal capping system seals the printhead of either a single-chamber or a multi-chamber style inkjet cartridge, such as a black ink cartridge or a multi-color ink cartridge installed in an inkjet printing mechanism. In an imaging inkjet cartridge system, the normal single-chamber black cartridge for printing text is replaced with a multi-chamber imaging cartridge. Some imaging cartridges carry ink formulations having reduced colorant concentrations, which, when used in conjunction with a full color cartridge carrying full colorant concentrations of color inks, provides near photographic image quality, as well as crisp black text and line art. The printing mechanism is provided with a universal capping system, including several banks of flexible sealing sublips, capable of sealing either style cartridge when installed. One sublip has an asymmetrical cross section selected to control the direction of bending. The cap is spring-biased to push the sealing lips into engagement with the installed printhead.
