| 发明名称 | Applying electric fields to erase regions of a print medium | ||
| 摘要 | In an embodiment, an ink erasing system includes an erase fluid dispenser to apply erase fluid to a surface of a print medium. The system includes a plurality of nonadjacent pairs of electrodes positioned across a width of the print medium. The system also includes a controller to direct the erase fluid dispenser to apply the erase fluid in an erase region on the print medium, and to alternately electrify the nonadjacent pairs of electrodes to generate a moving electric field through the erase region. | ||
