Part 1: Safety and Precautions

BJC-7100

3.NOTES ON SERVICING

3.1EEPROM Data

The printer stores the function settings and keeps track of various information including the total sheets printed, the number of cartridge replacements, the total waste ink amount, and the head position adjustment values. The data is stored in the EEPROM on the logic board.

Note the following precautions during servicing:

1) Before servicing

You can 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 replacement

Always replace the waste ink absorber when replacing the EEPROM.

If you do not replace the waste ink absorber, the data on waste ink amount will differ from the amount of ink that can be absorbed by the waste ink absorber. There is therefore a risk of ink leaking.

When replacing the logic board, be sure to reset all the data. Because the data on new EEPROMs is undefined, they cannot be used until they are reset. For details of handling EEPROMs, see "Part 3: 3.4 EEPROM" (page 3-19).

3) After waste ink absorber replacement

After replacing full waste ink absorbers, reset the EEPROM's waste ink counter.

4)If you accidentally reset the EEPROM's waste ink amount data or all data Once reset, the EEPROM data cannot be restored. If you accidentally reset the EEPROM, you must take the same steps as when replacing the logic board.

After the EEPROM is reset, the data it contained cannot be printed out with a test print. If you want to check the stored data, be sure to make a test print before resetting the EEPROM.

Note that you cannot reenter the data from the printer's control panel or by using a computer.

If the EEPROM is faulty, or all data is reset, all data is lost. Whenever possible, restore all data such as the head alignment to the user's settings.

During operation, the waste ink amount (EEPROM data) is automatically

updated. An error message is displayed and operation halted when the

waste ink absorber is nearly full. If this occurs, refer to "Part 5: 6. TROUBLESHOOTING" (page 5-13).

See "Part 3: 3.8.3 Printing EEPROM data" (page 3-23)for how to make a test print of the stored data.

You can choose to either reset the waste ink counter or all data. See "Part 3: 3.8.2 Resetting EEPROM data" (page 3-22)for details.
