Page 21: General Information
4514 General information The Lexmark MS315, MS415, and M1140+ are network‑capable, multi‑function laser printers that print monochrome print jobs. 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

(electrophotographic) printers. While no blanket statement can be made that all recycled paper will feed well, Lexmark consistently tests papers that represent recycled cut size copier papers available on the global market. This scientific testing is conducted with rigor and discipline.
Page 24: Storing Paper
4514 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).
Page 25: Using Specialty Media
4514 • Do not store anything on top of individual paper packages. • Take paper out of the carton or wrapper only when you are ready to load it in the printer. The carton and wrapper help keep the paper clean, dry, and flat. Using specialty media Tips on using card stock Card stock is heavy, single‑ply specialty media.

Page 277: Appendix C: Theory Of Operation
4514 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 278: Simplex Printing
4514 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.

4514 Part First input roller Secondary input roller Duplex front deliver roller Duplex rear deliver roller Paper exit roller Media handling components Main drive gearbox The gearbox supplies all mechanical power requirements of the printer. Its motor, through several gears, transfers power to following paths: photoconductor drum, transfer roll, fuser, paper exit, input, duplex, and MPF.

Among other capabilities, this sensor can be used to determine the paper size sensor and the media stack height.

4514 Pass through sensor (option tray) Detects when the media from the option tray passes. This will trigger the pick roller to pick the next media. Capactive Toner Level Sensor (CTLS) Detects the amount of toner in the imaging unit. If the toner level is low, the cartridge auger motor is triggered to add toner from the toner cartridge to the imaging unit.
Page 283: Electrophotographic Process (Ep Process)
4514 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 284 4514 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 285 4514 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 Drum Surface...
