ABSTRACT:
An inkjet cartridge refurbishing apparatus includes a pump assembly with a fluid intake line that can be inserted into a bottle or other reservoir of ink or flushing/cleaning material. Connected to the output of the pump assembly is a fill gun having a fill needle mounted on a handle. The fill gun is operated by inserting the fill needle into an inkjet cartridge and actuating a fill trigger switch on the fill gun. Actuating the fill trigger switch activates the pump assembly to pump ink into the cartridge. An auto-cutoff device may control the volume of fluid pumped into the cartridge.
