7.4 Resetting the EEPROMThe EEPROM stores information such as the various settings; the total printed sheet count of the black,color, and photo BJ cartridges and scanner cartridge; the total waste-ink absorption amount; and the errorhistory of the last three non user-recoverable errors. The printer uses the total waste-ink absorption amountrecorded by the EEPROM as the basis for determining whether the waste ink is full. Therefore, afterreplacing the waste-ink absorber, be sure to reset the EEPROM's total waste-ink absorption amount.Also, after replacing the control board, be sure to reset the new control board's EEPROM and to alsoreplace the waste-ink absorber.7.5 Setting the Model with the EEPROMThe control board used in the BJC-6200 is also used in other printers. After replacing the control board, thedefault information for the respective printer must be set.After setting the model, confirm it with the service/factory test printout.7.6 Ink Availability CheckWhen this function is selected, the printer scans the carriage to check for ink in the ink tank's inkcompartments. The result is printed out.Whether the ink sensor is working properly can be confirmed by:(1) Installing an empty ink tank in the BJ cartridge.(2) Using this Service Mode function and print out the results.(3) Checking that the "ExistInk" value is 0 (indicating an empty ink tank).7.7 Auto Print Head Position AdjustmentThe print head position can be adjusted with the printer alone, without connection to a computer. Theadjustment is the same as when the user executes the auto printing position adjustment via the computer.For details on the head printing position adjustment, see3.4.3 Print head position adjustment on page2-19.7.8 Power Off/Carriage LockWhen this function is selected, the printer moves the carriage (whether BJ cartridges are installed or not) tothe home position and locks the carriage. Then the power turns off.2-31BJC-6200Part 2: Troubleshooting Troubleshooting
