ABSTRACT:
A gear arrangement for a capper of an inkjet printer comprises a first gear assembly mounted to the printer so as to cooperate with a motor gear for driving rotation of the first gear assembly, the first gear assembly having a code feature; and a second gear assembly mounted to the printer so as to cooperate with the first gear assembly to be rotatable therewith, the second gear assembly, in use, cooperating with a capper for capping a printhead so that the rotation of the second gear assembly moves the capper out of and into its capping position. The code feature of the first gear assembly is arranged to cooperate with a holding feature of a mounting arrangement used to mount the second gear assembly to the printer, the code feature being configured so that the cooperation with the holding feature maintains the first gear assembly at a predetermined position during the mounting of the second gear assembly. A common shaft is mounted connecting the first gear and two second gears to the body so that each of the second gears mesh with the second gear assembly. A pin of two third gears is mounted to the body so that each of the third gears mesh with a respective one of the second gears of the first gear assembly.
