The media size is detected by the on/off information of these switches.
Page 34 7500-XXX Sensor (media level) This sensor detects by the actuator position whether media in the media tray assembly is lifted. When the flag of the actuator unblocks the sensing area of the sensor (media level), the sensor detects that the media has been lifted.
Page 35: Multi-Purpose Feeder (Mpf)
7500-XXX Multi-purpose feeder (MPF) The MPF is a mechanical unit suppling media to the printer. The driving force from the transport motor of the dual drive motor assembly is transmitted to the MPF feed roll to feed media. MPF pick roll The MPF pick roll feeds media set on the MPF and into the feeder.
Page 36: Detecting Media Size
7500-XXX Detecting media size The size of media on the MPF is transmitted by moving the MPF side guide, and is determined by the printer engine card assembly. Media sizes that can be automatically detected are as follows: Media size Width (mm) Feed length (mm) Side-guide stopper (min.)
Page 37: Registration
7500-XXX Registration Sensor (registration) The sensor (registration) must be installed before the registration roll assembly can detect whether media exists in the registration path.

Page 49 7500-XXX 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 50 7500-XXX The charge roll is a conductive roll that is positioned slightly above the surface of the drum. The HVPS supplies the charge roll with two voltages; a negative DC charge voltage and an AC discharge voltage that is used for electrically cleaning the drum.
Page 51 7500-XXX The Printhead also helps to clean and prepare the drum by scanning the surface of the drum at the beginning of each individual printer cycle. This action discharges a residual DC charge that may still remain on the Drum from the last print cycle.
Page 52 7500-XXX 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 53 7500-XXX Transfer As the paper travels between the Transfer Roll and the drum surface, the Transfer Roll applies a positive charge to the back of the printing paper. This positive charge transfers the negative charged toner image from the drum surface to the top surface of the paper.
Page 54 7500-XXX Cleaning The Cleaning Blade removes any toner that remains on the drum after the transfer process. The toner that the Cleaning Blade removes is collected inside the sealed PC Cartridge and reused. Used Toner Cleaning Blade Charge roll DRUM Discharge At both the start and the end of each individual printer cycle, the HVPS supplies the charge roll with an AC voltage that is used to electrically clean the drum.

Page 56: Document Scanning
7500-XXX 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 57: Document Scanning At Adf
7500-XXX The full rate carriage and half rate carriage travel to read the document. 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.
Page 58 7500-XXX First the pick roll moves down and presses the document on the document tray to enable document feed. The pick roll moves down with the normal rotation of the pick roll position motor assembly and it moves up with the reverse rotation of the pick roll position motor assembly.
Page 59: Scan Control
7500-XXX 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 60: Simplex Document
7500-XXX ADF exit roll assembly Document Inverter gate Simplex document For two simplex document sheets, feed is performed in the following sequence: The first document sheet is fed to the ADF transport roll assembly. (see Pre-feed) The document is fed to the ADF registration roll assembly, and then fed to the scan feed reference position.
Page 61: Duplex Document
7500-XXX 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 62 7500-XXX 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. After the predetermined time, the ADF registration motor starts rotating in the reverse direction (CCW direction) to drive the ADF registration roll assembly and ADF feed-out roll assembly in the exit direction in order to feed the document sheet (Side 1).
