The Lexmark™ 4600 MFP option is a multifunction solution that offers integrated print, copy, fax, and color network-scanning capabilities for increased small workgroup productivity. The option is easy to use and provides low-cost access to key office functions, including fax from workstation, network color copying, scanning, and electronic document routing. Give your document to the option, and in a few steps, it scans to the network and delivers it wherever, to whomever you want. With this scanner, inefficient trips to the mailroom, copier, fax machine and to your workstation are a thing of the past. This manual is for maintenance engineers. It describes the maintenance areas, installation, disassembly, and the main troubleshooting guides.
Take your time to read this manual thoroughly to obtain comprehensive knowledge about the scanner before servicing the unit.
