摘要： A method of refreshing a sticky cleaner used for cleaning a fuser member in an electrophotographic printer is disclosed. The method includes the steps of precoating the cleaner member with a low cost polymer toner material prior to a printing operation removing contaminants from the sticky surface of the cleaner member. A refreshed cleaning member prior to being used to clean a fuser in an electrophotographic printer in accordance with the features of the present invention includes a surface cleaning member having minimal contaminants thereon, and a coating of a plastic toner material that can become tacky at the operating cleaner temperatures.

摘要： A color xerographic printing apparatus exhibiting a very high toner transfer efficiency. A rough-surfaced or bumpy Intermediate Transfer Belt (ITB) provides reduced contact area between toner particles and the ITB. Adhesion forces between the ITB and toner images deposited thereon are minimized thereby reducing the electrostatic forces required for transferring toner images from the ITB to a final imaging substrate or a transfuse belt. The bumpy configuration enables use of small quantities of release agent material such as silicone oil for further enhancing toner image transfer without transfer silicone oil to various components of the apparatus including an imaging member such as a photoreceptor.

摘要： An apparatus for enabling a conductive backed photoconductive intermediate transfer member in an electrophotographic printing apparatus with pre-charge and light assist. The printing apparatus includes a toner transfer system having an intermediate transfer belt comprising a highly conductive transparent substrate with a charging device and an illumination lamp. The intermediate transfer belt is pre-charged prior to entering a transfer nip region to generate low or reverse fields therein. Subsequently, the photoconductive layer of the intermediate surface is exposed to light energy to discharge the pre-charge thereon, generating high transfer fields in the transfer nip.

摘要： A charging device provided with an integral arrangement for tensioning coronodes. The charging device is useful for mounting a double length prefabricated wire coronode having a predetermined length, and provided with coronode connectors at each end. The device includes first and second insulating end blocks supporting the coronode in charging position with respect to a surface to be charged, at least one of the end blocks adaptable for electrically connecting the coronode to a power supply, a coronode support member supported on the first end block for supporting a looped end of the coronode at the first end block and a coronode tensioning arrangement on the second end block, for applying tension to the coronode, including a pivot member for supporting the free ends of the coronode and mounted for pivoting movement between first and second positions. The first position of the pivoting movement allows connection of the coronode connector to the coronode connector anchor while the coronode is untensioned, and the second position of the pivoting movement applies a selected tension to the coronode.

摘要： In an electrostatographic copying system where a toner image on a photoreceptor is transferred to a copy sheet with transfer charges, which charges are removed from the copy sheet by passing the copy sheet under a detacking corona generator, the body of the copy sheet is supported to insure its stripping from the photoreceptor at a point under the detack corona generating electrode where the transfer charge thereon is only partially neutralized, while a restricted minor area of the lead edge of the copy sheet is stripped further downstream, where it has been substantially fully neutralized, at a fixed position controlled by a mechanical stripper finger.

摘要： Embodiments described herein are directed to a system for reducing electrostatic fields underneath print heads in a direct marking printing system. The system includes: one or more print heads for depositing ink onto a media substrate; a media transport for moving the media substrate along a media path past the one or more print heads; a conductive platen contacting the media transport belt; and an electrostatic field reducer that includes an alternating current corona device positioned upstream of the one or more print heads. The media transport includes a media transport belt and, when the media substrate is on the transport belt it has an electrostatic field, which can cause printing defects. The electrostatic field reducer reduces the electrostatic field on the surface of the media substrate and thereby reduces printing defects.

摘要： Disclosed is a method and apparatus for sensing residual toner mass after transfer of a xerographic image, to facilitate the identification and characterization of different types of transfer defects. The technique employed utilizes a nominal residual mass signature, measured at the start of a job, in conjunction with subsequent residual mass signature, where the calculated difference between the nominal and subsequent signatures is used to indicate transfer defects and changes in transfer efficiency.

摘要： An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet. The sheet passes through a nip formed between the charge receptor and a moving transfer belt. Upstream of the nip, the belt forms a shallow angle relative to the charge receptor; downstream of the nip, the belt forms a steep angle relative to the charge receptor. This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.

摘要： An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet by providing an electric field of predetermined magnitude at a transfer zone. The transfer station includes a rotatable transfer member, with a cleaning corotron associated therewith. A control system for maintaining a constant current at the transfer zone takes into account a current supplied by the cleaning corotron. The control system can also take into account current leakages associated with the transfer member.
