An easily removable and reusable improved holding pin device and method for securing together the sections of a toner cartridge assembly for use in imaging machines. The holding pin comprises a shank with a tapered head structured to allow easy gripping of the holding pin by pulling tools by using the taper which forms a recess in the head so the head will abut for easy grabbing with a conventional pulling tool for easy removal. The gripping parts of a tool may extend through this recess space to grip or otherwise contact the head of the holding pin, allowing the holding pin to be pulled from the assembly without damage to the holding pin or cartridge assembly. In another embodiment of the holding pin there is a first portion of the head that is tapered and a second portion of the head that is not tapered so that the tapered portion forms a recess so the second portion is easy to grab and is also set in precise position so as not to stick out too far. In another embodiment of the holding pin there are three portions. The first portion is greater in diameter than bore and the shank to set the position, a second portion is smaller in diameter than the first portion to abut the third portion which is larger in diameter than the second portion so the holding pin is easy to grip for removal and the first and second portions recess the third portion for easy grabbing for removal with conventional pulling tools. Also a tool has been developed for holding pin removal for difficult to remove holding pins that must be pushed out from the inside toward the outside. The tool has a handle and a base. The base may be perpendicular or nearly perpendicular to the handle and have two ends that are like hammerheads and a press-fit pin is positioned at each end and is used to remove the difficult to remove holding pins by pounding the holding-pins out. When pounding out holding pins, the laser light slot may be used as a guide for straight and consistent holding pin removal. Also, when pounding out holding pins, the wiper blade metal frame corner crevice may be used as a guide for straight and consistent and flawless holding pin removal.
