Page 32 7462 Weight The printer can automatically feed paper weights from 60–176 g/m (16–47 lb bond) grain long. Paper lighter than 60 g/m (16 lb) might not be stiff enough to feed properly, and may cause paper jams. For best performance, use 75 g/m (20 lb bond) grain long paper.
Page 33: Using Recycled Paper And Other Office Papers
Lexmark consistently tests its printers with recycled paper (20–100% post-consumer waste) and a variety of test paper from around the world, using chamber tests for different temperature and humidity conditions. Lexmark has found no reason to discourage the use of today's recycled office papers, but generally the following property guidelines apply to recycled paper.

Page 652 7462 Media tray assembly It is necessary to adjust the media tray rear guide and media tray side guide of the media tray assembly to match the media size. Rear media guide The rear media tray guide assembly can be adjusted to different media sizes by moving it to the front or rear. The rear guide should come into contact with the media and hold it in position.
Page 653: Media Tray Assembly
7462 Media tray assembly Wear strips Side guides End guides Detection of media size The media size set for the media tray assembly is transmitted to the switch (media size) by moving these guides. The media size is detected by the on/off information of these switches. Appendix C: Theory of operation...

The pick arm assembly is a mechanical unit supplying media from the media tray assembly to the printer.
Page 655 7462 Sensor (media low) This sensor detects by the actuator position whether media in the media tray assembly is low. When the ﬂag of the actuator blocks, then unblocks the sensing area of the sensor (media low), the media level is determined to be low.
Page 656: Registration
7462 Registration Part Aligner assembly Sensor (input) Sensor (input) The sensor (input) is located just before the print cartridge and can detect whether media exists in the input path. Aligner assembly The aligner assembly is used to feed the media through the input path and to ensure that media is fed through the machine in a perfectly straight manner and not in a skewed manner.
Page 657: Transfer
7462 Transfer Transfer roll Transfer roll assembly The transfer roll assembly applies charge to the rear surface of the media when the media passes between the transfer roll assembly and photo conductor (drum). Thus, the toner image is transferred from the photo conductor (drum) surface to the media surface.
Page 658 7462 Polygon printhead Part Polygon printhead LD card assembly — This generates the laser beam. The beam is turned on or off according to a print data signal coming from the system card. Printhead motor/polygon mirror — The polygon mirror is mounted to the shaft of the printhead motor, and is rotated at a high speed by the printhead motor.
Page 659: Fuser
7462 When a laser beam is scanned across the photoconductor (drum) surface from one end to the other while turning on and off the beam, one line of latent image is created. If the scanning by the laser beam is repeated while rotating the drum, a two-dimensional image is created.

This tube is heated by the inner heater lamp. The heat is applied to the media passing between the heat roll and pressure roll, fusing the toner on the media.
Page 662 7462 Thermistor The thermistor monitors the surface temperature of the media-feed portion of the heat roll to control on/off of the main heater lamp and sub heater lamp. Sensor (fuser output) The sensor (fuser output) detects the arrival of media at the detection point in the exit area of the fuser, and also detects the ejection of media from this point.

7462 Part Sensor (standard bin exit) Sensor (standard bin full) The sensor (standard bin full) detects whether the standard bin is full by moving the actuator up and down. Drive Main drive motor assembly The main drive motor is a DC motor that drives the print cartridge, aligner, MFP, and fuser. Redrive motor assembly The redrive motor assembly is a DC motor that drives the redrive assembly that transports the media into the standard bin or output option.

7462 Electrical components and controller Part LVPS card assembly Duplex cooling fan Print cartridge cooling fan HVPS card assembly System card assembly Main cooling fan Switch (printer front door interlock) The switch is a safety switch to cut off a 24 VDC power supply from the LVPS card assembly to the high volt power supply (HVPS) card assembly, printer system card assembly and to the main drive motor assembly, while the printer front door assembly is open.
Page 666: Printhead Control
7462 LVPS card assembly The LVPS card assembly generates low voltages 5V for logic circuits, 5V for laser diodes, and 24V for cooling fans. The LVPS is switchable and can be switched to work with 100V, 110V, and 220V machines. LVPS cooling fan The LVPS cooling fan discharges air from the LVPS to prevent excessive temperature increases.
Page 667: Fuser Control
7462 Fuser control Fuser control method The on/off control of the main/sub heater lamps is performed based on the fuser control temperature. The fuser transmits between the ﬁve states (warm up, ready, standby, print, and low power) depending on the heat roll surface temperature or printer conditions.
Page 668 7462 Part Waste toner collection Drum Developer roll 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.
Page 669 7462 This discharge/no discharge process creates an invisible, electrostatic image on the surface of the drum. This image is called a latent image. Modulated Laser Beam Printhead DRUM Drum Surface Drum Surface Image Voltage Laser Beam Laser Beam Discharge Level Invisible Latent Image Development The toner contained within the PC cartridge has an electrical property that causes it to adhere to the...
Page 670 7462 The toner adhering to the development 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. There is now a visible toner image on the drum surface.
Page 671 7462 Transfer As the paper travels between the transfer roll and the photoconductor (drum), the transfer roll applies a charge to the back of the printing paper. This positive charge transfers the negative charged toner image from the photoconductor (drum) to the top surface of the paper. The toner image is now on the paper and the paper is now stuck to the photoconductor (drum) 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.
Page 672: Document Scanning At Adf
7462 Auto density sensing 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. Part Sensor shield assembly Sensor (toner density) The image density sensor assembly uses a reﬂection type sensor that detects a pre-placed toner patch and image on the photoconductor (drum) and outputs pulses when the central line of the patch image aligns with the central line of the detector.

Page 675 7462 Part Lockable back restraint Media end guide Auto size ﬁnger actuator Rear media tray guide Media size sensing The media size set for the media tray assembly is set by positioning the right media guide, unlocking the slider lock, and sliding the rear paper guide. The rear paper guide triggers the movement of the auto size sensing ﬁnger, which then sets the switches of the controller card board.
Page 676 7462 Media level sensing The media level for the media tray assembly is triggered by the actuator ﬂag positioned in the two photointerrupter sensors in the pick arm bracket assembly. The actuator ﬂag blocks and unblocks the two sensors in different sequence; it determines whether the paper tray is empty, low, or full. 250-sheet tray Sensor A Sensor B...

Page 727 Print defects guide Page 1 of 1 Print defects guide Match a set of repeating defects on a print job to the marks on one of the vertical lines. The line that best matches the defects on the print job indicates which particular part may be causing the defect. For example, the distance between these two marks represents a repeating defect that occurs every 28.3 mm (1.11 in.), which means the charge rollers may need to be replaced.
