Abstract: What is disclosed is an apparatus and method for inhibiting the formation of sediment in an ink tank of a MICR inkjet printer. In one embodiment, the present apparatus comprises an ink tank containing MICR ink and an electromagnet which resides in a chamber located on, near, or inside the ink tank. Activation of the electromagnet causes the particles to be attracted to the electromagnet's magnetic field such that the particles are lifted off a bottom of the tank to inhibit sediment formation thereon. The electromagnet can be activated in response to the MICR inkjet printer having been turned OFF. A sensor may further be employed to activate the electromagnet in response to one of: sediment in the ink tank having reached a pre-determined level; a flow-rate of liquid ink through the tank having fallen below a threshold level, sediment levels, or a pressure inside the tank.

Abstract: What is disclosed is an object holder for retaining an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder has a back support configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A top and bottom arm are attached to the back support. At least one retention bit is attached to each of the top and bottom arms for collectively retaining the object to the object holder.
