SAFETY AND PRECAUTIONS

1. SAFETY PRECAUTIONS

1.1 Moving Parts

The moving parts of the printer are shown below. They include the carriage belt, idler roller, carriage, slow down gear, paper feed roller, pressure roller, eject roller, spurs, and pick-up roller. The first three parts above are driven by the carriage motor while the latter are driven by the paper feed motor. Avoid getting hair, clothing, jewelry, etc., caught in these moving parts. Also note that the spurs are made of metal and have sharp edges. Avoid touching the spurs with bare hands.

1.2 Ink Stains

1.2.1 Ink path

Do not touch the ink path while servicing as the ink can stain hands, work table, clothing, etc. The ink path consists of the BJ cartridge nozzles, head cap, head wiper, maintenance jet receiving section, and waste ink absorber. In the case of color BJ cartridges, the cartridge’s ink outlets and joint pipes are also part of the ink path.

Part 1: Safety and Precautions

BJC-2000

Figure 1-2 Ink Path

Caution!

Although the ink is non-toxic, it contains organic solvents. Isopropyl alcohol 67-63-0, glycerin 56-81-5, and ethyleneglycol 107-21-1 in black ink and isopropyl alcohol 67-63-0 in color inks. Do not get ink in your eyes and mouth. If any ink should get into your eyes, wash with plenty of water and consult a doctor. If a large amount of the ink is consumed, consult a doctor immediately. Give the doctor the information on the BJ cartridge label. Since the ink contains dyes, any ink stains on clothing, etc., are permanent.

1.2.2 Ink mist

The BJ cartridge ejects ink onto the paper. During prolonged or heavy-duty use of the printer, small amounts of ink mist which splatter off paper during printing can contaminate the inside of the front cover and platen. Clean any contaminated parts with a soft moist cloth. Ink in such areas can contaminate the back of the paper and dirty hands and clothing while servicing.

1.3 BJ Cartridge Heat-Up

Do not touch the BJ cartridge’s aluminum plate. The aluminum plate heats up during printing and becomes particularly hot during prolonged and continuous printing. It can overheat also if printing is continued even after the cartridge has run out of ink.

The printer has a protective mechanism when the BJ cartridge heats up. The protective mechanism is activated when the head temperature (diode) sensor in the BJ cartridge senses a certain temperature. Protection level 1:

This level prevents the user from touching the bubble jet head’s hot aluminum plate when the bubble jet head is replaced. For this purpose, when the front cover is opened, the carriage will not move to the cartridge replacement position. Close the front cover, leave the printer inactive for a few minutes to allow it to cool, and then open the front cover again to perform the required operation.

Protection level 2:

If a high temperature is still detected, the carriage is returned to the home position for 3.5 seconds to bring down the temperature. After the resting period, printing will resume. This continues for over 20 seconds to lower the bubble jet head’s temperature.

Protection level 3:

If the temperature continues to increase, a head temperature error occurs. This stops the printing operation.

When printing is stopped by a head temperature error or a head temperature sensor error, follow the troubleshooting procedures in

2. MACHINE PRECAUTIONS

2.1 Precautions for Handling BJ Cartridges

2.1.1 Turning the printer ON/OFF

The printer will automatically cap the cartridge heads one minute after printing operations are completed, to prevent the ink from leaking and drying out. When unplugging the power cord, wait at least one minute after completing an operation such as printing, feeding paper, cleaning the print head, etc. If the power cord is accidentally unplugged before one minute has passed, replug the AC adapter, and wait for more than one minute before unplugging the power cord.

If the nozzles are not capped, the ink may leak and dry out causing the nozzles to clog.

2.1.2 When the printer is not in use

BJ cartridges should be stored either installed in the printer or in the BJ cartridge container.

If the BJ cartridge is removed from the printer or BJ Cartridge Container, the ink may leak and dry out causing the nozzles to clog.

2.1.3 Transportation Precautions

When carrying or transporting the printer, keep the BJ cartridge stored in the BJ cartridge container. This prevents the ink from leaking and drying out in the nozzles.

2.1.4 Ink electroconductivity

The ink in the BJ cartridge is electroconductive. If ink leaks into the printer’s mechanical parts, use a damp paper towel, etc., to wipe clean. If it leaks into the printer’s electrical components, use tissue paper, etc., to wipe clean completely. If ink gets into the IC chips on the PCB and it is difficult to clean, replace the PCB.

If ink has leaked inside the printer, do not plug in the power cord. It may damage the circuitry.

CAUTION

2.2 Printer Precautions

2.2.1 Spur deformation prevention

Do not deform the tips of the spurs. The spurs come into contact with the paper after printing. As the actual contact surface is small, any ink adhering to the spurs is minute and wiped off by the spur cleaners. Therefore any ink on the spurs is not enough to contaminate the paper as it passes. However, if the spurs become deformed, their contact surface with the paper increases, causing more ink to adhere to each spur. Since the spur cleaner is unable to wipe off all the ink, a line of dotted ink may mask the printed paper.

2.2.2 Static electricity damage prevention

The static charge that accumulates from clothing, etc., can damage electrical components. Therefore, never touch the electrical contacts of the carriage ribbon cable and BJ cartridge.

3. PRECAUTIONS FOR SERVICE

3.1 EEPROM Data Precautions

The printer keeps track of various settings, the total waste ink amount, and the total sheets printed with the black, color and photo BJ cartridges. This data is stored in the EEPROM on the logic board. Note the following precautions during servicing:

1) Before servicing

Check the EEPROM data with a test print. The total sheets printed can give you an idea of how much the printer has been used.

2) During logic board (EEPROM) replacement

Always visually check the waste ink amount absorbed by the waste ink absorbers and replace them when necessary as explained in

Part 5: 4.3 Logic Board and Bottom

Cover Replacement Cautions (page 5-5).

If the waste ink absorbers are not visually checked regularly, they may reach or exceed their full capacity before “waste ink full” is detected. The waste ink may therefore start leaking. The memory data for the replacement logic board (EEPROM) is not defined. Therefore, after replacing the logic board (and EEPROM), reset the total waste ink amount to zero by clearing the data.

3) After waste ink absorber replacement

After replacing the waste ink absorbers, reset the total waste ink amount to zero by clearing the EEPROM data.

After the EEPROM is reset, the data it contained cannot be printed out with a test printout. If you want to check the stored data, be sure to execute test printout before resetting the EEPROM. When the stored data is reset, the various settings, the total count of printed sheets, and the total waste ink amount will all be reset. The total sheets printed and waste ink amount cannot be input using the operation panel.

Immediately after the printer is turned on, it keeps track of the estimated waste ink amount based on the usage conditions. To prevent ink leakage when the waste ink amount exceeds the waste ink absorption capacity, the printer stops printing and indicates an error when the waste ink absorption capacity is close to being full. For details on checking the EEPROM data with a test printout and for clearing the data, see

Part 3: 2.4 EEPROM Reset (page 3-19)

. If the printer stops operating in the case of a waste ink full error, follow the countermeasures described in

Part 5: 5.1 Troubleshooting (page 5-6)
