    摘要: A transfer station for toner transfer in an electrophotographic imaging device includes an endless transfer belt transported about an endless path through the imaging device, a transfer roll adjacent one surface of the transfer belt, and a backup roll adjacent an opposite surface of the transfer belt opposite from the transfer roll such that the transfer roll and backup roll form a transfer nip effecting transfer of toner. For the purpose of improved overtransfer performance, an outer layer of a thin polymer coating is applied to at least one of the transfer belt and the rolls so as to be located within the transfer nip with transfer of toner. The polymer layer has a thickness from about 5 μm to about 200 μm, surface resistivity from about 1E08 to about 1E12 Ohm/cm and breakdown strength greater than 500 V.

    摘要: An improved color EP (laser) printer is provided for use in high humidity conditions. A humidity sensing circuit determines if the print quality might be degraded due to environmental conditions, using a resistivity sensing circuit, or a humidity sensor. If the print quality would likely be degraded, the invention is able to enhance toner transfer by printing supplemental process black toner dots underlaying standard black toner dots at predetermined pixel locations in the bitmap of a print job. This assumes that the black printing station is the “last” station along the travel of the intermediate transfer member. Other colors could be used for the supplemental toner dots.
