Page 59: Charge
7510 Charge 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. HVPS Charge roll (-VDC)
Page 60: Exposure
7510 Exposure 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 charged drum surface.
Page 61: Transfer
7510 The toner adhering to the Magnet Roll is always in contact with the drum surface. When a less negative point on 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.
Page 62: Cleaning
7510 is now stuck to the transfer belt due to the relative electrical differences between the negative electrical charge of the inner conductive layer of the drum and the positive electrical charge of the paper. HVPS -VDC DRUM -VDC Transfer roll Sheet of paper Cleaning The Cleaning Blade removes any toner that remains on the drum after the transfer process.
Page 63: Auto Density Sensing
7510 At the beginning of each individual printer cycle, the Printhead scans the surface of the drum, further discharging any residual DC charge that may be left on the drum. Erase lamp LED array DRUM Ground Auto density sensing Image density sensor assembly The image density sensor assembly uses a reflection type sensor that detects a pre-placed toner patch and image on the transfer belt and outputs pulses when the central line of the patch image aligns with the central line...
Page 64: Document Scanning
7510 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. 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 scanner unit assembly is fixed.
Page 65: 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 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 66: Pre-Feed
7510 Pre-feed 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.
Page 67: Scan Control
7510 ADF transport roll assembly ADF registration roll assembly Scan control Scanning of the image illuminated with the exposure lamp of the full rate carriage is controlled by changing the feed speed according to the copy magnification. The document sheet stopping at the scan feed reference position is then fed to the scan position when the scan signal is sent from the main unit of the machine after the predetermined time lapse following the paper detection at sensor (ADF registration).
Page 68: Simplex Document
7510 ADF exit roll assembly Document Inverter gate Simplex document For two simplex document sheets, feed is performed in the following sequence: 1. The first document sheet is fed to the ADF transport roll assembly. (see Pre-feed) 2. The document is fed to the ADF registration roll assembly, and then fed to the scan feed reference position.
Page 69: Duplex Document
7510 Sensor (ADF pre-registration) 2nd documant 1st document Duplex document The ADF scans the image on Side 1 (side facing up when set on the tray), inverts the document sheet, scans the image on Side 2 (side facing down when set on the tray), and then ejects the document sheet while inverting Therefore, the duplex document sheet is ejected with Side 2 up as with the simplex document sheet.
Page 70 7510 When the sensor (ADF pre-registration) detects the lead edge of document sheet (Side 1), the inverter solenoid assembly is turned on to release the nipped ADF exit roll assembly and exit pinch roll, and the ADF registration motor decelerates and stops. 12.

A signal indicating the set size is transmitted as a voltage to the printer engine card assembly. Sensor (media out) If there is no media in the media tray assembly, the media out actuator lowers and the flag of the media out actuator that has stayed in the sensor (media out) sensing area leaves there.
