ABSTRACT:
Direct electrostatic printing (DEP) is enhanced by the provision of a shutter mechanism for preventing toner dislodged from the backside of a printhead structure from being deposited on copy substrates. The shutter is interposed between the printhead structure and the copy substrate during a cleaning cycle. The dislodged toner is removed from between the printhead structure and the copy substrate with a combination vacuum and toner collection device.
