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.

CHAPTER 2 ERROR INDICATION AND TROUBLESHOOTING

WARNING

2.1 INTRODUCTION

This section gives the service personnel some of the troubleshooting procedures to be 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.

2.1.1 Precautions

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

WARNING

DO NOT use flammable substances or organic solvent such as alcohol, benzine, thinner or any type of spray to clean the insi de 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.

Confidential

Page 32

2.1.2 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) Each voltage level on AC input lines and DC lines is correct. (3) All cables and h arnesses are firmly connected. (4) The fuses are not blown.

Recording paper Check that:

(1) A recommended type of recording paper is used. (Refer to Chapter 1, Section 1.11

"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

5.1.4.27.)

These rollers pull in recording paper from paper tray #1. These rollers pull in recording paper from paper tray #2.

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. In manual paper feeding, this detects whether recording paper is set on the manual feed slot.

This also detects paper jams 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 recordi ng paper to the switchback 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 roller, as well as judgi ng 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 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.
