20120008965 | CURRENT MONITORING TO DEFECT PHOTORECEPTOR SCRATCHES - A method monitors an electric current supplied to an electrostatic brush within a printing device. The electrostatic brush contacts and cleans a photoreceptor surface within the printing device. The method records a current spike pattern of when the electric current exceeds a first current threshold during the monitoring; however, the method will stop operations of the printing device if the electric current exceeds a second current threshold that is greater than the first current threshold. Further, the method can determine whether a scratch is present on the photoreceptor surface based on the current spike pattern. | 01-12-2012 |
20130021418 | METHOD AND SYSTEM FOR DELIVERING SOLID-INK PELLETS - The present disclosure provides apparatus and method for supplying uninterrupted flow of solid-ink pellets to an image-forming device. The apparatus includes a container for retaining solid-ink pellets, and a selectably-inflatable bladder disposed within the container. Further, the apparatus includes a tube communicating the bladder with a pressure supply. | 01-24-2013 |
20130100203 | SYSTEM FOR INK REMOVAL FROM A PRINTHEAD ASSEMBLY - A printhead cleaning device includes a housing having an opening and an ink receptacle positioned within the opening. A member extends from the ink receptacle and through the opening. The member is configured to contact a faceplate of a printhead to enable liquid ink emitted onto the faceplate to move from across the member into the ink receptacle. | 04-25-2013 |
20130201254 | APPARATUS AND METHOD FOR REMOVAL OF INK FROM AN EXTERIOR OF A PRINTHEAD - In an inkjet printing apparatus, a heater heats a drib bib that is located below a plurality of inkjets in a printhead to a temperature that melts ink collected on a surface of the drip bib. Pressurized air is directed toward the surface of the drip bib to remove the melted ink from the surface of the drip bib. | 08-08-2013 |
20130300800 | THREE POSITION PRINTHEAD WIPER ASSEMBLY - A printhead wiper assembly includes an elongated member having a first and second wiper, a linkage, and an actuator. The linkage includes a clutch that enables the elongated member to move to a plurality of positions in response to the actuator activating a plurality of times. The sequence of positions enables first wiper and then the other wiper to contact the printhead face to remove purged ink from the face. | 11-14-2013 |
20130307909 | Solid Ink Printer with Magnetic Ink Mixing - A phase change inkjet printer is equipped with an agitator to prevent settling of metal particles in melted magnetic phase change ink. The agitator operates to agitate the melted magnetic phase change ink as the ink enters the printhead to maintain the metal particles in suspension within the melted ink. | 11-21-2013 |
20150283818 | METHOD AND APPARATUS FOR DELIVERING SOLID-INK PELLETS - The present disclosure provides apparatus and method for supplying uninterrupted flow of solid-ink pellets to an image-forming device. The apparatus includes a container for retaining solid-ink pellets, and a selectably-inflatable bladder disposed within the container. Further, the apparatus includes a tube communicating the bladder with a pressure supply. | 10-08-2015 |
