Claim:
1. A method for inhibiting sediment from forming in an ink tank of a Magnetic Ink Character Recognition (MICR) inkjet printer, the method comprising: disposing at least one sealed chamber inside an ink tank; a magnet disposed inside said sealed chamber; and activating an electromagnet of said ink tank containing an aqueous solution of liquid MICR ink substantially comprising a ferrofluid of particles thereby rotating said magnet to stir at least a portion of said particles in said ink tank to inhibit sediment formation, and said particles being attracted to said electromagnet's magnetic field such that at least a portion of said particles are lifted off a bottom of said ink tank to inhibit sediment formation thereon, and whereby said sealed chamber prevents said liquid MICR ink from contacting said magnet.
