Page 19: Preface
4514-420, -430 Preface This manual contains maintenance procedures for service personnel. It is divided into the following chapters: • General information contains a general description of the printer. Special tools and test equipment are discussed. • Diagnostic information contains diagnostic aids you can use to isolate failing FRUs. These diagnostic aids include error code tables, symptom tables, and service checks.

Page 21: General Information
4514-420, -430 General information The Lexmark MS410d and MS410dn are single‑function monochrome laser printers designed for small and mid‑sized workgroups. All information in this service manual pertains to all models unless explicitly noted. The printers are available in the following models:...
Page 22: Moisture Content
4514-420, -430 Smoothness Paper smoothness directly affects print quality. If paper is too rough, toner cannot fuse to it properly. If paper is too smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300 Sheffield points; smoothness between 150–250 Sheffield points produces the best print quality.
Page 23: 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 24: Using Specialty Media
4514-420, -430 • Suitable smoothness (100–200 Sheffield units, or 140–350 Bendtsen units, European) Note: Some much smoother papers (such as premium 24 lb laser papers, 50–90 Sheffield units) and much rougher papers (such as premium cotton papers, 200–300 Sheffield units) have been engineered to work very well in laser printers, despite surface texture.

4514-420, -430 Appendix C: Theory of operation POR sequence At power on, the engine code goes through a series of tests to verify hardware integrity. If a hardware failure is detected, it will be reported to the printer. If the POR sequence cannot be completed successfully, the printer may post an error message identifying service may be needed.
Page 246: Simplex Printing
4514-420, -430 The MPF can be accessed by opening the MPF tray on the front door. In an MPF paper feed, the MPF paper present sensor detects the media. The instant the MPF pick roll shaft rotates, the cams on each end of the shaft disengage the MPF tray.
Page 247: Duplex Printing
4514-420, -430 Duplex printing After the first side of the media has been printed on and is partially fed out to the output bin, the duplex solenoid activates. This causes the exit roller to reverse its rotation and feed the media, with its trailing edge first, back into the redrive assembly and then to the duplex paper path.

Page 251: Electrophotographic Process (Ep Process)
4514-420, -430 Electrophotographic process (EP process) Printhead The printhead scans the photo conductor drum surface with a laser beam. It consists of the following components: • Laser diode (LD) card assembly • Oscillator • Start of scan card assembly 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.
Page 252 4514-420, -430 Step 2: Expose The laser fires a focused beam of light at the surface of the photoconductor and writes an invisible image, called a latent image. The laser beam only discharges the surface where the beam hits the photoconductor. This creates a difference in charge potential between the exposed area and the rest of the photoconductor surface.
Page 253 4514-420, -430 This process would be similar to using glue to write on a can and then rolling it over glitter. The glitter sticks to the glue but not to the rest of the can. HVPS Developer Metering Roll Blade Toner DRUM -VDC...
