Lexmark concerns itself with the responsible use of paper in general based on life cycle assessments of its products. To gain a better understanding of the impact of printers on the environment, the company commissioned a number of life cycle assessments and found that paper was identified as the primary contributor (up to 80%) of carbon emissions caused throughout the entire life of a device (from design to end-of-life).
4063 Storing paper Use these paper storage guidelines to help avoid jams and uneven print quality: • For best results, store paper where the temperature is 21°C (70°F) and the relative humidity is 40 percent. Most label manufacturers recommend printing in a temperature range of 18–24°C (65–75°F) with relative humidity between 40 and 60 percent.

4063 Adjustments • “Media aligner roller adjustment” on page 269 • “Polygon printhead mechanical registration adjustment” on page 270 The printer skew specification calls for image skew on the registration sheet to be one dot (0.5mm) or less delta between the left and right alignment indicators for the top and bottom margins.
Page 268
4063 Select Quick Test Page. The test page should only be printed on letter or A4 paper from Tray 1. The Quick Test Page consists of alignment diamonds and horizontal lines that can be used for mechanical registration adjustment. The following image shows an example of the Quick Test Page: Review the page to determine which type of skew is present.
4063 Media aligner roller adjustment Complete the media aligner roller adjustment procedure when you replace the media aligner roller. Always print a copy of the Quick Test Page before making any adjustments to the media aligner roller reference adjustment screw. Note: When replacing the media aligner roller, back the reference adjustment screw out far enough to remove the old media aligner roller and install the new one.
4063 Step C Print a copy of the Quick Test Page, and check the top and bottom alignment indicators printed on the test page. The goal is to make the skew at the top and bottom of the page parallel. Depending on the skew, turn the screw either clockwise or counterclockwise using a 3mm hex wrench, and print a copy of the Quick Test Page to check the diamonds on the top and bottom margin.
Page 271
4063 To perform the printhead mechanical registration adjustment: Print a Quick Test Page. See “Adjustments” on page 267. If the skew between the bottom left and bottom right alignment indicators is greater than 0.5mm (1 dot), then proceed with adjustment. Otherwise, no polygon printhead adjustment is needed.
4063 Check the Quick Test Page for any sign of misalignment by checking the diamonds at the bottom left and bottom right of the test page for equal distance from the bottom of the page. If necessary, rotate the printhead adjusting screw with a 3mm hex wrench either clockwise (to rotate the image clockwise) or counterclockwise (to rotate the image counterclockwise), and run another Quick Test Page.

Rear media guide The rear media tray guide assembly can be adjusted to different media sizes by moving it to the front or rear and can be locked in position.
4063 Media tray • “Media feeder” on page 592 • “Sensor (media size)” on page 592 • “Sensor (pick roller position)” on page 592 Media feeder The pick roller assembly which is part of the media feeder, is a mechanical unit supplying media from the media tray to the paper path.
4063 The MPF is a mechanical unit supplying media to the printer. The driving force from the main drive motor drive motor is transmitted to the MPF pick roller to feed media. MPF pick roller The MPF pick roller feeds the media placed in the MPF media tray into the printer. MPF pick solenoid The MPF pick solenoid transmits the driving force from the main drive motor assembly to the MPF pick roller.
4063 Sensor (input) The sensor (input) is located just before the print cartridge and can detect whether media exists in the input path. The sensor is used to detect jams and to set functional timing. Duplex • “Sensor (duplex path)” on page 594 The printer has an integrated duplex that is used to provide two-sided printing.
4063 Printhead The printhead scans the photoconductor drum surface with a laser beam. It consists of four components: laser diode (LD) card assembly, printhead motor, polygon mirror, and the start of scan card assembly. LD card assembly—The LD card assembly generates the laser beam. The beam is turned on or off according to a print data signal coming from the controller board.
4063 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.
4063 Heat belt (belt fuser) The heat belt is a thin metal belt with a coated surface. This belt is heated by a ceramic heater bar. The heat is applied to the media passing between the heat belt and pressure roll, fusing the toner on the media. Heat belt (hot roll fuser) The heat roll is a hollow metal tube with a coated surface.
4063 Sensor (fuser exit) The sensor (fuser exit) detects the arrival and departure of media as it passes through the fuser. Sensor (narrow media) (hot roll fuser only) The sensor (narrow media) detects the arrival and departure of media as it passes through the fuser. It also detects the width of the media.
4063 Drive • “Main drive motor assembly” on page 599 • “Fuser drive motor assembly” on page 599 • “Toner add motor assembly” on page 599 • “Redrive motor assembly” on page 599 Main drive motor assembly The main drive motor is a DC motor that drives the imaging unit, aligner, and MFP. Fuser drive motor assembly The fuser drive motor is a DC motor that drives the fuser.
4063 Sensor (control panel door interlock) The sensor is a safety device to cut off a 24 VDC power supply from the LVPS to the high volt power supply (HVPS), controller board, and to the main drive motor assembly, while the control panel door is open. Sensor (rear door interlock) The sensor is a safety device to cut off a 24 VDC power supply from the LVPS to the HVPS, controller board, and to the main drive motor assembly, while the printer rear door is open.
4063 LVPS board assembly The LVPS board assembly generates 6.5V and 25V DC voltages. The LVPS can be switched to work with 100V, 110, and 220V machines. HVPS board assembly The HVPS board assembly generates and provides DC voltages to the developer roll, the transfer roller, and the charge roller (located in the imaging unit).
Page 603
4063 Exposure The Printhead generates a beam of laser light. Image data received from the controller board 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 604
4063 Development The toner contained within the PC cartridge has an electrical property that causes it to adhere to the development roller. The metering blade spreads the toner into a very thin layer on the development roller. Friction between the development roller and the CM blade development roller generates a small electrical charge that is transferred to the toner.
Page 605
4063 Transfer As the paper travels between the transfer roller and the photoconductor (drum), the Transfer roller applies a positive 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.
4063 Auto density sensing 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.

4063 The main motor drives the transport rollers which move the media along the paper path. The sensor (pass through) detects if the media has entered the expander. The diverter of the expander controls which way the media will go. If the diverter is closed, then the media will exit into the output bin.
4063 Upon exit, the media is fed out by the exit rollers towards the output bin. The sensor (bin full) verifies if the media has exited. The media level on the output bin is detected by the actuator flag. When the output bin is full, the actuator flag triggers the sensor (bin full).
4063 Staple finisher theory The staple finisher is capable of compiling multiple pages and stapling them into one document. Motors drive the stapling process and sensors detect the media's position and location. Staple finisher paper path When the finisher is installed on top of the printer, the diverter plunger changes the position of the diverter below it. Since the diverter position of the printer below is opened, the printed paper will be re-routed.
