ABSTRACT:
For cleaning the print heads of an electrographic printer, a cleaning strip (900) or a lapping strip (1000) is applied to a medium (10) which moves through the printer. The strip (900 or 1000) is first positioned between fiducial marks printed on the medium (10). Then a solvent or other "conditioning agent" is optionally applied to the strip. Then the strip is moved backward into the printer and positioned over at least one electrographic print head (40). The medium (10) is optionally moved back and forth and/or the print head (40) is optionally moved back and forth. This action accomplishes cleaning or lapping of the electrographic print head. After use, the strip, still affixed to the medium (10) is moved away from the printing area and printing resumes. The process is equally applicable in single-pass and multi-pass printers.
