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.
iii
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.
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).
iv
SAFETY PRECAUTIONS
To use the machine safely
Please refer to these instructions for later reference and before attempting any maintenance.
WARNING


There are high voltage electrodes inside the
machine. Before you clean the machine,
make sure you have unplugged the
telephone line cord first and then the power
cord from the AC power outlet.

(Safety_1)


Do not handle the plug with wet hands. Doing
this might cause an electrical shock.

(Safety_2)


To prevent injuries, be careful not to put your
hands on the edge of the machine under the
scanner cover.

(Safety_3_MFC)


To prevent injuries, be careful not to touch
the area shaded in the illustration.

(Safety_4)


When moving the machine you must lift it
from the base, by placing a hand at each side
of the unit as shown in the illustration. Do
NOT carry the machine by holding the
scanner cover.


(Safety_5_MFC)

v
WARNING

Use caution when installing or modifying telephone lines. Never touch telephone wires or terminals that are
not insulated unless the telephone line has been disconnected at the wall jack. Never install telephone
wiring during a lightning storm. Never install a telephone wall jack in a wet location.
This product must be installed near an AC power outlet that is easily accessible. In case of emergencies, you
must disconnect the power cord from the AC power outlet in order to shut off power completely.
To reduce the risk of shock or fire, use only a No. 26 AWG or larger telecommunication line cord.

Caution

Lightning and power surges can damage this product! We recommend that you use a quality surge
protection device on the AC power line and on the telephone line, or unplug the cords during a lightning
storm.
When lifting up the machine, hold it from the base. Do not hold the scanner cover (scanner unit); doing so
causes the machine body to be inclined, which may disengage the scanner cover from the machine body and
lead to falling of the machine body.


IMPORTANT SAFETY INSTRUCTIONS
When using the machine, basic safety precautions should always be followed to reduce the risk of
fire, electric shock and injury to persons, including the following:
1. Do not use this product near water, for example, near a bath tub, wash bowl, kitchen sink or
washing machine, in a wet basement or near a swimming pool.
2. Avoid using this product during a lightning storm. There may be a remote risk of electric shock
from lightning.
3. Do not use this product to report a gas leak in the vicinity of the leak.
4. Use only the power cord provided with the machine.
SAVE THESE INSTRUCTIONS
vi
Choosing a location
Place the machine on a flat, stable surface that is free of vibration and shocks, such as a desk. Put the machine
near a telephone wall jack and a standard, grounded AC power outlet. Choose a location where the temperature
remains between 50°F and 95°F (10°C and 35°C).
Caution

Avoid placing the machine in a high-traffic area.
Avoid placing the machine on the carpet.
Do not place the machine near heaters, air cond itioners, water, chemicals, or refrigerators.
Do not expose the machine to direct sunlight, excessive heat, moisture, or dust.
Do not connect the machine to electrical outlets controlled by wall switches or automatic timers.
Disruption of power can wipe out information in the machine’s memory.
Do not connect the machine to electrical outlets on the same circuit as large appliances or other equipment
that might disrupt the power supply.
Avoid interference sources, such as speakers or the base units of cordless phones.
