REGULATION

 Standard telephone and FCC notices

These notices are in effect on models sold and used in the United States only.

When

programming emergency numbers or making test calls to emergency numbers:

• Remain on the line and briefly explain to the dispatcher the reason for the call before hanging
up.

• Perform these activities in the off-peak hours, such as early morning or late evening.

This equipment complies with Part 68 of the FCC rules and the requirements adopted by the
ACTA. On the backside of this equipment is a label that contains, among other information, a
product identifier in the format US: AAAEQ##TXXXX. If requested, this number must be
provided to the telephone company.

You may safely connect this equipment to the telephone line by means of a standard modular
jack, USOC RJ11C.

A plug and jack used to connect this equipment to the premises wiring and telephone network
must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. A
compliant telephone cord and modular plug is provided with this product. It is designed to be
connected to a compatible modular jack that is also compliant. See installation instructions for
details.

The REN is used to determin e t he number of devices that may be connected to a telephone line.
Excessive RENs on a telephone line may result in the devices not ringing in response to an
incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be
certain of the number of devices that may be connected to a line, as determined by the total
RENs, contact the local telephone company. For products approved after July 23, 2001, the
REN for this product is part of the product identifier that has the format
US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point
(e.g., 06 is a REN of 0.6). For earlier products, the REN is separately shown on the label.

If this equipment causes harm to the telephone network, the telephone company will notify you
in advance that temporary discontinuance of service may be required. But if advance notice isn't
practical, the telephone company will notify the customer as soon as possible. Also, you will be
advised of your right to file a complaint with the FCC if you believe it is necessary.

Handling and using print media

 Store paper in its original packaging, and keep it sealed. Keep the paper flat and away from

moisture, direct sunlight and heat.

 Avoid touching the shiny (coated) side of photo paper. Load photo paper with the shiny side

facing down.

 Avoid touching either side of transparencies because they absorb water and perspiration

easily, and this may cause decreased output quality. Transparencies designed for laser
printers/copiers may stain your next document. Use only transparencies recommended for
inkjet printing.

 You can only print on both sides of the paper with PC printing using Windows.

CHAPTER 2 ERROR INDICATION AND TROUBLESHOOTING

WARNINGWARNING

1 INTRODUCTION

This section gives the service personnel some o f the trou bleshootin g proced ures to b e followed
if an error or malfunction occurs with the machine. It is impossible to anticipate all of the
possible problems which may occur in future and determine the troubleshooting procedures, so
this section covers some sample problems. However, those samples will help service personnel
pinpoint and repair other defective elements if he/she analyzes and examines them well.

1.1 Precautions

Be sure to observe the following to prevent any secondary troubles from happening during
troubleshooting.

DO NOT use flammable substances or organic solvent such as alcohol, benzine, thinner or
any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or
electrical shock.

Always unplug the AC power cord from the outlet when removing the covers and PCBs,
adjusting the mechanisms, or conducting continuity testing with a circuit tester.

(1) When disconnecting the connectors, do not pull the lead wires but hold the connector

housings.

(2) Static electricity charged in your body may damage electronic parts.

Before handling the PCBs, touch a metal portion of the machine to discharge static
electricity charged in your body. When transporting PCBs, be sure to wrap them in
conductive sheets.

When replacing the PCBs, 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.
(3) Be sure to observe the warnings.
(4) After repairing the defective section, be sure to check again if the repaired section works

correctly.

2-1

Confidential

1.2 Initial Check

Prior to proceeding to the troubleshooting procedures, make the following initial checks:

Environmental conditions
Check that:

(1) The machine is placed on a flat, firm surface.
(2) The machine is used in a clean environment at or near normal room temperature (10°C to

35°C) with normal relative humidity (20 to 80%).
(3) The machine is not exposed to direct sunlight, excessive heat, moisture, or dust.

Power requirements
Check that:

(1) The power supply specified on the rating plate on the machine is used. The supply voltage

stays within the rating ±10%.
(2) All cables and harnesses are firmly connected.
(3) The fuses are not blown.

Recording paper
Check that:

(1) A recommended type of recording paper is used. (Refer to Chapter 1, Section 11

"PAPER.")

(2) The recording paper is not dampened.

Ink cartridges
(1) Check that all of four ink cartridges are loaded.

Head/carriage unit
(1) Repeat the purge operation (Function code 76) several times. (Refer to Chapter 5, Section

1.4.28.)

Names Functions
Paper pull-in rollers These rollers pull in recording paper from the paper tray.

Paper feed sensor actuator

This detects whether recording paper is fed from the paper tray by

detecting the leading edge of the paper for driving the intermediate

roller.

This also detects paper jams in the rear section of the machine.
Intermediate roller

This stops the leading edge of recording paper for alignment

(registration).

After registration, this roller rotates to feed the recording paper to

the paper feed roller.
Registration sensor actuator

This detects the leading and trailing edges of recording paper for

indicating the printing start position and for judging the paper size,

respectively.

This also detects paper jams inside the machine and in the rear

section of the machine.
Paper feed roller

This feeds recording paper to the printing position.
Recording paper ejection roller This feeds printed recording paper to the switchback (SB) roller.

Switchback paper detection
actuator

This detects whether printed recording paper is ejected.

In duplex printing, it detects the trailing edge of the paper after

printing on the first side to determine the reversing timing of the

switchback (SB) roller, as well as judging the paper size.

In duplex printing, it also detects whether recording paper has

passed through the DX chute or jammed in the DX chute.

This also detect paper jams in the paper ejection section.
Switchback (SB) roller

DX roller

This ejects recording paper to the paper ejection tray.

In duplex printing, after feeding of recording paper printed on its

first side by the specified amount, this roller reverses to feed the

paper to the duplex print paper path.

In duplex printing, this roller feeds paper passing through the duplex

print paper path, to the intermediate roller.
