Multifunction devices combine the essentials of a fax machine, printer, scanner, and copier into one peripheral for small and home offices. As the market for this equipment grows, the need for skilled repair and maintenance increases. Unfortunately the service documentation supplied by the manufacturers is completely inadequate making the repair jobs even harder and more expensive. Marvin Hobbs teaches you how multifunction peripherals work in theory and in practice with lots of hands-on examples and important troubleshooting and repair tips you don't want to miss.
This book fills a gap in the literature, and will be a welcome addition to the library of any technician or do-it-yourselfer.
Written by a knowledgeable practitioner with inside industry information
Fully covers the troubleshooting and repair of multifunction peripherals
A must-have instructional and reference title for anyone who works with computer peripherals

This resource explains how multifunction peripherals work in theory and in practice, with lots of hands-on examples and important troubleshooting and repair tips.
-Poptronics

Hobbs's guide includes very clear technical illustrations, an abbreviation guide, a glossary of terms, troubleshooting flow charts, and operational theory. While general guides cover many multifunction device maintenance and repair issues, this book provides valuable information on the special failures that come with complicated modern multifunction devices. - Library Journal 2004
