Page 371 7017-2xx, -4xx, -6xx Charge Charge roller Photoconductor drum A uniform negative electrical charge is applied by the charge roller to the surface of the photoconductor drum. The photoconductive properties of the surface material allow it to hold the charge as long as it is not exposed to light.
Page 372 7017-2xx, -4xx, -6xx Expose Photoconductor drum Printhead The printhead emits the light that contacts the surface of the photoconductor drum. The light turns on or off coinciding with the digital latent image. The light causes areas of the photoconductor drum surface to lose charge, resulting in a relative opposite polarity.
Page 373 7017-2xx, -4xx, -6xx Develop Developer roller Toner cartridge Photoconductor drum The developer unit applies the toner from the toner cartridge to the photoconductor drum. The difference in charge causes the toner particles to attract to the photoconductor drum areas which are exposed to light. Theory of operation...
Page 374 7017-2xx, -4xx, -6xx Transfer Charge roller Transfer roller Paper The transfer roller applies a positive charge to the paper, which is pressed between the transfer roller and the photoconductor drum. Due to relative opposite polarities between the paper, from the transfer roller, and the photoconductor drum, from the charge roller, the charge attracts the toner onto the paper.
Page 375 7017-2xx, -4xx, -6xx Fuse Fuser Paper Even if the toner image is already on the paper, the toner particles are not yet permanently bonded to the surface. For the ﬁnal part of printing, the paper is transported to the fuser where heat and pressure are applied to it.

The separator roller feeds the paper to the second input roller, which feeds it to the ﬁrst input roller.
Page 378 7017-2xx, -4xx, -6xx The deskew shutter along the ﬁrst input roller corrects the skew on the paper. The ﬁrst input roller feeds the paper to the transfer roller. At the transfer roller, the photoconductor drum transfers the developed image to the paper to create the printed image. As the paper passes the fuser, heat and pressure are applied to permanently bond the toner to the paper.

Page 381: Tray Drive
7017-2xx, -4xx, -6xx Tray drive Pick roller Separator roller To prepare for feeding, the lift plate raises to push the paper against the pick roller. The lift plate stops pushing at the point where the pick roller is at the proper height for picking. After the pick roller is in position, it feeds the topmost paper to the separator roller.

7017-2xx, -4xx, -6xx ADF and scanner operation Flatbed scanner drive Scanner glass Motor (FB scanner) Sensor (FB CIS home) The ﬂatbed scanner has a scanner lamp that is used to illuminate the surface of the document. The reﬂections produced are processed to create the scan image. For ﬂatbed scan jobs, the ﬂatbed scanner moves across the scanner glass area to scan the front side of the document (facedown).

Page 384: Adf Paper Path Sensors
7017-2xx, -4xx, -6xx The paper then actuates the sensors (pick and deskew). The sensor (pick) detects the leading edge of the paper and adjusts the pick/feed timings while the sensor (deskew) detects the paper for any skews. The deskew roller slows down the paper to perform the skew correction.
