PREFACE

This publication is a Service Manual covering the specifications, construction, theory of operation,
and maintenance of the Brother facsimile equipment. It includes information required for field
troubleshooting and repair--disassembly, reassembly, and lubrication--so that service personnel will
be able to understand equipment function, to rapidly repair the equipment and order any necessary
spare parts.

To perform appropriate maintenance so that the facsimile equipment is always in best condition for
the customer, the service personnel must adequately understand and apply this manual.

This manual is made up of six chapters and appendices.
