Abstract: A packing removal tool for removing packing from a fluid end of a plunger pump includes a rod which is elongated between a front end and a rear end of the rod. A ram is coupled to the front end of the rod, and the ram is shaped such that the ram is configured for inserting into a channel of the fluid end through an access opening of the fluid end and engaging the packing. A disc is coupled to the rod and is positioned between the front and rear ends of the rod. The disc has outer threads on an outer annular surface of the disc which are configured for threadedly engaging internal threads of the channel of the fluid end adjacent to the access opening. The disc is also movable forwardly and rearwardly with respect to the rod.

Abstract: In printing apparatus, when printing near the end of a print media with a printhead having nozzles, a controller causes a print drive to produce a large print media advance movement together with the use of a different group of nozzles from that used for the rest of the print media. This avoids printing art effects as the print media leaves a pinch in a media feed. In one embodiment the number of nozzles used for printing in the end region is reduced, and the centre of the group of nozzles is simultaneously shifted in the direction of print media advance. The size of the print media advance is also changed in the end region. The printing mask used is also changed.
