ABSTRACT:
Disclosed is a device and method for removing the lid of an inkjet cartridge. The device holds the cartridge within two jaws, which secure only the bottom of the cartridge. A driving mechanism is used to pop off the top of the cartridge in order that it may be refilled. The driver is J-shaped and has long and short prongs connected by a cross member. A screw within a bulkhead is used to push the driver from the back. This causes the long prong to bear against the top of the cartridge to remove it. The short prong assists in guiding the driver. A spring pushes back on the driver the further it is driven. This enables the user to retract the driving member once the top of the cartridge has been removed. A shelf is formed on all of the jaws of the holder. One jaw has an overhang portion which, with the shelf, forms a channel. Many commercially available cartridges are configured with a rib at their midsection. The shelf and channel act to receive this rib so that the cartridge may be held securely. Also disclosed is a shim which is inserted into the device so that it may accommodate smaller-sized cartridges.
