Abstract

An inkjet printer that has a printhead and a plurality of printing fluid reservoirs, each of the printing fluid reservoirs storing a different type of printing fluid. A refill interface on the printer allows the printing fluid reservoirs to be refilled by docking with a range of refill dispensers. Each of the refill dispensers in the range contains one of the types of printing fluid stored in one of the printing fluid reservoirs. The docking interface has docking formations for engagement with complementary formations on each of the refill dispensers in the range respectively such that the refill interface can dock with only one of the refill dispensers at any one time. The refill interface also having an array of printing fluid inlets, each of the printing fluid inlets being in fluid communication with one of the printing fluid reservoirs respectively and being individually positioned with respect to the engagement formations such that they form a fluid connection with only the refill dispensers holding printing fluid of the type corresponding to the printing fluid reservoir to which it is connected. Individually refilling the printing fluid reservoirs can be more economical and better suited to individual usage profiles. A single refill interface simplifies the refill process for the user while the individualized fluid inlet positions avoid ink contamination from user error.
