Page 61: Charge
7510 Charge Previous The Charge Roll places a uniform negative electrostatic charge on the surface of the drum. The drum surface is made of a photoconductive material that holds an electrical charge as long as the drum remains in darkness. Light striking the drum discharges the surface charge.
Page 62: Exposure
7510 Exposure Previous The Printhead generates a beam of laser light. Image data received from the RIP card assembly modulates this beam, turning it on and off according to image information that is received from the host computer and software. Through the use of a series of rotating and stationary mirrors within the Printhead, the beam scans the negative Next charged drum surface.
Page 63: Transfer
7510 The toner adhering to the Magnet Roll is always in contact with the drum surface. When a less negative point on Previous the drum (a discharged area) comes in contact with the more negative charged toner on the Magnet Roll, toner transfers from the Magnet Roll to that point on the drum.

7510 Previous Document scanning The document scanning section of this machine consists of a scanner that reads a single-sheet document placed on the platen glass and a document feeder that can transport a multiple-sheet document and flip the sheets for two-sided scanning. Next This ADF employs a constant velocity transport system that scans images by feeding the document at a constant speed over the specified position (scan position) where the carriage (full/half rate carriage) of the...
Page 67: Document Scanning At Adf
7510 The exposure lamp is installed on the full rate carriage. As the full rate carriage travels, the document on the Previous platen glass is scanned and exposed with the exposure lamp. In conjunction with the full rate carriage, the half rate carriage travels half of the stroke of the full rate carriage. The optical image of the exposed document is reflected by the scanner 1st mirror of the full rate carriage and directed to the scanner lens via the scanner 2nd mirror and the scanner 3rd mirror of the half rate carriage.
Page 68: Pre-Feed
7510 Pre-feed Previous In the pre-feed step, a document sheet is fed from the Feed roll to the ADF transport roll assembly. To correct the skew, side1 of the document sheet is thrust against the ADF transport roll assembly rotating in the reverse direction, and side2 is thrust against the ADF transport roll assembly at rest.
