Brother Fax Machine FAX2580C 2480C User Manual

Preface  
This Service Manual is intended for use by service personnel and details the specifications,  
construction, theory of operation, and maintenance for the Brother machines noted on the front cover.  
It includes information required for troubleshooting and service--disassembly, reassembly, and  
lubrication--so that service personnel will be able to understand equipment function, repair the  
equipment in a timely manner and order spare parts as necessary.  
To perform appropriate maintenance so that the machine is always in the best possible condition for  
the customer, service personnel must adequately understand and apply this manual.  
The table below shows the functional comparison between the models covered by this manual.

How this manual is organized  
This manual is made up of nine chapters and appendices.  
CHAPTER 1 PARTS NAMES AND FUNCTIONS  
Contains external views and names of components and describes their functions. Information about  
the keys on the control panel is included to help you check operation or make adjustments.  
CHAPTER 2 SPECIFICATIONS  
Lists the specifications of each model, which enables you to make a comparison of different models.  
CHAPTER 3 THEORY OF OPERATION  
Gives an overview of the scanning and printing mechanisms as well as the sensors, actuators, and  
control electronics. It aids in understanding the basic principles of operation as well as locating  
defects for troubleshooting.  
CHAPTER 4 ERROR INDICATION AND TROUBLESHOOTING  
Details error messages and codes that the incorporated self-diagnostic functions display if any error  
or malfunction occurs. If any error message appears, refer to this chapter to find which components  
should be checked or replaced.  
The latter half of this chapter provides sample problems that could occur in the main sections of the  
machine and related troubleshooting procedures. This will help service personnel pinpoint and  
repair defective components.  
CHAPTER 5 TRANSFER OF DATA LEFT IN THE MACHINE TO BE SENT FOR REPAIR  
Describes how to transfer data left in the machine to be sent for repair. The service personnel  
should instruct end users to follow the transfer procedure given in this chapter if the machine at the  
user site cannot print received data due to the printing mechanism defective. End users can transfer  
received data to another machine to prevent data loss.  
CHAPTER 6 DISASSEMBLY/REASSEMBLY AND LUBRICATION  
Details procedures for disassembling and reassembling the machine together with related notes. The  
disassembly order flow provided enables you to see at a glance the quickest way to get to  
component(s) involved.  
At the start of a disassembly job, you check the disassembly order flow that guides you through a  
shortcut to the target components.  
This chapter also covers screw tightening torques and lubrication points to which the specified  
lubricants should be applied during reassembly jobs.  
CHAPTER 7 ADJUSTMENTS AND UPDATING OF SETTINGS, REQUIRED AFTER PARTS  
REPLACEMENT  
Details adjustments and updating of settings, which are required if the head/carriage unit, main PCB  
and some other parts have been replaced.  
CHAPTER 8 CLEANING  
Provides cleaning procedures not covered by the User's Guide. Before starting any repair work,  
clean the machine as it may solve the problem concerned.

CHAPTER 9 MAINTENANCE MODE  
Describes the maintenance mode which is exclusively designed for the purpose of checks, settings  
and adjustments of the machine using the keys on the control panel.  
In the maintenance mode, you can update memory (EEPROM: electrically erasable programmable  
read-only memory) contents for optimizing the drive conditions of the head/carriage unit or the paper  
feed roller and paper ejection roller in the engine unit, if those units have been replaced, or for setting  
the CIS scanner area, for example. You can also customize the EEPROM according to the shipment  
destination of the machine concerned. In addition, you can perform operational checks of the LCD,  
control panel PCB or sensors, perform a print test, display the log information or error codes, and  
modify firmware switches (WSW).  
For models with a cordless handset, the maintenance functions dedicated to cordless handsets are  
provided.  
Appendix 1 Reading Labels  
Shows the location of labels put on some parts and describes the coding information for serial  
number, property data, and manufacturing information.  
Appendix 2 Firmware Installation  
Provides instructions on how to change firmware stored in the flash ROM on the main PCB or load  
firmware to a new main PCB from the host PC.  
Appendix 3 EEPROM Customizing Codes  
Provides instructions on how to set up the EEPROM customizing codes for the various preferences  
exclusively designed for each destination. The specified customizing code is stored in the EEPROM  
mounted on the main PCB. If the main PCB is replaced, therefore, you need to set up the proper  
customizing code with the machine in the maintenance mode.  
Customizing codes customize firmware for individual models, enabling the common firmware to be  
used for various models. A list of EEPROM customizing codes comes with the firmware data  
provided by Brother Industries.  
Appendix 4 Firmware Switches (WSW)  
Describes the functions of the firmware switches, which can be divided into two groups: one is for  
customizing preferences designed for the shipping destination (as described in Appendix 3) and the  
other is for modifying preferences that match the machine to the environmental conditions. Use the  
latter group if the machine malfunctions due to mismatching.  
Appendix 5 Wiring Diagrams  
Provides the wiring diagrams that help you understand the connections between PCBs.  
Appendix 6 Circuit Diagrams  
Provides the circuit diagrams of the MJ PCB and power supply PCB.  
Appendix 7 Deletion of Personal Information  
Provides instructions on how to delete personal information recorded in the machine and cordless  
handset(s).
