Method and apparatus for servicing an inkjet print head

A printer carriage has a chute for removably holding a print cartridge, and includes a set of datums on a forward portion of the chute for positioning the print cartridge. A spring-loaded clamp is movable by a handle between an open position which allows easy insertion and withdrawal of the print cartridge from the chute, and a closed position which applies a clamping force against a back wall of the print cartridge. The clamping force is preferably applied in both a forward and downward direction against a lower portion of the back wall to securely hold the print cartridge in the chute against the datums, and to provide conductive contact through a plurality of electrical interconnects between the carriage and the print cartridge. A method of installation and removal of a print cartridge employs access along a primarily vertical path through an open top of the chute. A printing system with the carriage and print cartridge preferably expels ink along an approximately horizontal path from an upstanding nozzle plate
