Abstract
An adsorbent material is mounted on a nozzle plate of an ink jet printer to collect extraneous ink and particles that might otherwise clog the nozzle orifices of the printer. In ink jet printers, ink droplets are propelled from an array of orifices in a nozzle plate in the printer head. During the ink droplet ejection, ink is sprayed or deposited around the orifices. The ink droplets are deposited on a paper web adjacent the nozzle and mist from the droplets drifts back to coat the face of the nozzle plate. This ink coating attracts particles that tend to clog the nozzle orifices. By locating an adsorbent material in close proximity to the nozzle orifice array, the material adsorbs and removes ink coating the nozzle plate before the ink clogs the orifices of the nozzle. A thread is an example of an adsorbent material. The thread slides in a groove across the face of the nozzle plate to draw off the ink coating and particles on the nozzle plate. A thread dispenser bobbin on one side of the printer head supplies clean thread to the printer head and a rewind bobbin on the other side of the printer head draws the thread across the nozzle plate and off the dispenser bobbin.
