Safety Precautions
To use the machine safely
Please keep these instructions for later reference and read them before attempting any maintenance.
• If there are faxes in the machine's memory, you need to print them or save them before you turn off
the power and unplug the machine.
WARNING
There are high voltage electrodes inside the
machine. Before you clean the inside of the
machine, make sure you have unplugged the
telephone line cord first and then the power cord
from the AC power outlet.
Do not handle the plug with wet hands. Doing this
might cause an electrical shock.
After you use the machine, some internal parts are
extremely
to put your fingers in the area shown in the
illustration.
The fixing unit is marked with a caution label.
Please do not remove or damage the label.
• 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 walljack.
HOT! To prevent injures, be careful not

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 an
emergency, you must disconnect the power cord from the AC power outlet to shut off the power
completely.
Do not use a vacuum cleaner to clean up scattered toner. Doing this might cause the toner dust to ignite
inside the vacuum cleaner, potentially starting a fire. Please carefully clean the toner dust with a dry, lintfree cloth and dispose of it according to local regulations.
WARNING
DO not use any type of spray to clean inside or outside of the machine. Doing this may cause a fire or
electrical shock.
WARNING
IMPORTANT SAFETY INSTRUCTIONS
When using your telephone equipment, basic safety precautions should always be followed to reduce
the risk of fire, electric shock and injury to people, 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 an electrical storm. There may be a remote risk of electric shock

Installation Requirement
Choosing a Location
Place your 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 90.5°F (10°C and 32.5°C).
• Avoid placing your machine in a high-traffic area.
Do not place the machine near heaters, air conditioners, water, chemicals, or refrigerators.
•
• Do not expose the machine to direct sunlight, excessive heat, moisture, or dust.
• Do not connect your machine to an AC power outlet controlled by wall switches or automatic timers.
• Disruption of power can wipe out information in the machine's memory.
• Do not connect your machine to an AC power outlet 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.

When
for sending the machine for repair will lose received FAX data if unprinted and left in the machine.
To prevent such data loss, the service personnel should instruct end users (e.g., by telephone) to transfer
data to another facsimile machine using the procedure below.
• The number of files that can be transferred at a time is 99. To transfer 100 files or more, carry out the
following procedure more than one time.
Operating Procedure
1. Connect the machine to be repaired (that has received data in the memory) to the telephone line.
2. Switch the machine on.
3. Press the "Menu/Set", "Start", "Menu/Set", "0", "5" and "3" keys in this order to access useraccessible functions of the maintenance mode.
The "FAX TRANSFER" appears on the LCD.
4. To check the number of received files, press the "1" key.
The "1.NO. OF JOBS" appears on the LCD.
Press the "Menu/Set" key, and the number of received files appears, just as "NO. OF. JOBS:10".
5. To transfer the activity report only, press the "2" key.
The "2.ACTIVITY" appears.
To transfer received files together with the activity report, press the "3" key.
The "3.DOCUMENTS" appears. Note that if there is no received file, the "NO DOCUMENTS"
appears.
6. To transfer the communication list for the latest communication, press the "4" key.
The "4.COM.LIST (NEW)" appears.
To transfer the communication list for last three errors, press the "5" key.
The "5.COM.LIST (ERR3)" appears.
7. With the "2.ACTIVITY", "3.DOCUMENTS", "4.COM.LIST (NEW)" or "5.COM.LIST (ERR3)" being
displayed, press the "Menu/Set" key.
The "ENTER NO. &SET" appears.
8. Enter the telephone number of the receiver machine and press the "Menu/Set" key again.

Before You Do
Safety Precautions
To prevent the creation of secondary problems by mishandling, observe the following precautions during
maintenance work.
1. Before starting disassembly/reassembly jobs, unplug the power cord and telephone line. In particular,
when having access to the power supply inside the machine, make sure that the power cord is
unplugged from the electrical outlet; when having access to the main PCB or NCU PCB, make sure
that both the power cord and telephone line are unplugged from the machine.
2. Be careful not to lose screws, washers, or other parts removed for parts replacement.
3. When using soldering irons and other heat-generating tools, take care not to damage the resin parts
such as wires, PCBs, and covers.
4. Static electricity charged in your body may damage electronic parts. When transporting PCBs, be
sure to wrap them in conductive sheets.
5. When replacing the PCB and all the other related parts, put on a grounding wrist band and perform
the job on a static mat. Also take care not to touch the conductor sections on the flat cables or on the
wire harness.
6. Be sure to reinsert self-tapping screws correctly, if removed.
7. Tighten screws to the torque values listed on the next page.
8. After disconnecting flat cables, check that each cable is not damaged at its end or shortcircuited.
9. When connecting flat cables, do not insert them at an angle. After insertion, check that the cables are
not at an angle.
10. When connecting or disconnecting cable connectors, hold the connector bodies not the wires. If the
connector has a lock, always slide the connector lock to unlock it.
11. Before reassembly, apply the specified lubricant to the specified points.
(Refer to Section 5.2 in this chapter.)
12. After repairs, check not only the repaired portion but also that the connectors and other related
portions function properly before operation checks.
13. After you use the machine, some internal parts are extremely HOT! To prevent injuries, be careful not
to put your fingers in the areas shown in the illustration.

Preparation
Prior to proceeding with the disassembly procedure,
Unplug
1.
- the modular jack of the telephone line,
- the USB cable, if connected (not shown below), and
- the modular jack of the external telephone set if connected (not shown below).
How to Access the Object Component
On the next page is a disassembly flowchart which helps you access the object components. To remove
fixing unit, for example, first find it on the flowchart and note its name ("Fixing Unit"). To access it, you
the
need to remove all the parts above the fixing unit on the flowchart ("Back Cover"
"Side Cover R/Link Stopper" "Top Cover") before the unit itself can be removed.
"Rear Chute Cover"
otherwise specified, all parts should be replaced in the reverse order to which they were removed
Unless
