摘要： An impact printer with a hammerbank having print hammers retained by a permanent magnet (82) for impacting a print ribbon, and a mechanical driver for moving the hammerbank across print media. First and second coils (98, 100) for each hammer are wrapped around first and second pole pieces (84, 86), one of which is asymmetrical to the other pole piece. One of the pole pieces (84) can have a generally elongated longitudinal form with the coil (98) wound around the longitudinal form. The other (86) can have a generally arcuate form, with the coil (100) wrapped on a portion between the ends thereof. The coil (100) wrapped around the arcuately formed pole piece (86) is thicker than the coil (98) wrapped along the longitudinal pole piece (84). The result is to provide pole pieces and coils for an impact printer having differing spatial relationships that can be staggered, or formed asymmetrically for more compact coil and pole piece placement to improve printer efficiency.

摘要： An ink density closed loop control system for an ink ribbon (20) of an impact line printer (10) having a reservoir roller (36) fluidly connected to a pump and ink supply. A transfer roller (156) can contact the reservoir roller (36) for imparting ink to the ink ribbon (20). A sensor senses the relative amount of ink on the print ribbon (20) and an electrical drive responsive to the sensor drives the pump for a flow of ink to the one or more channels. The sensor can sense ink on different segments of the ribbon (20) and, with two or more channels in the reservoir roller (36) can distribute ink to two or more segments of the reservoir roller (36) depending upon the ink sensed at a particular segment of the ribbon (20). A further enhancement of the invention provides a multi-viscosity ink to compensate for changes in ambient temperature conditions.
