7462 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 and the maintenance approach used to repair it. Special tools and test equipment, as well as general environmental and safety instructions, are discussed.
7462 1. General information The Lexmark™ X651, X652, X654, X656 and X658 are All-In-One laser MFPs that provide print, copy, scan, and fax functions designed to attach to most computer networks. The operator panel is touch-sensitive and allows the user to adjust the viewing angle. All information in this service manual pertains to all models unless explicitly noted.
Floor-mounted configurations require additional furniture for stability. You must use either a printer stand or printer base if you are using a 2000-sheet drawer. Certain other configurations also must have a printer stand or printer base. More information is available on our Lexmark Web site at www.lexmark.com/multifunctionprinters.
7462 Supported paper sizes, types, and weights The following tables provide information on standard and optional paper sources and the types of paper they support. Note: For an unlisted paper size, select the closest larger listed size. Paper sizes supported by the printer 250-or 550-sheet Optional Multipurpose...

7462 2. Diagnostic information Start CAUTION: Unplug the power cord from the electrical outlet before you connect or disconnect any cable electronic board or assembly. CAUTION: If the printer is kept on, never touch the conductive parts if not specifically required. The power switch and inlet of the low voltage power supply card (LVPS card) assembly is live even while the power supply is cut off.
The following is an example of the events that occur during the POR sequence: Turn the machine on. The Lexmark splash screen appears with a progress bar in the center until the code is loaded. The fuser cooling fan turns on.

HVPS -VDC DRUM -VDC Transfer roll Sheet of paper 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.
7462 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. The sensor outputs pulses at the timing the patch image passes the sensor. Therefore, observing changes of intervals at which pulses are output leads to toner density detection.
7462 Document scanning at ADF 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 for one or two- sided scanning.
