BJC-6500 Part 3: OPERATION OPERATION 2.4 Resetting the EEPROM The EEPROM stores such information as function settings, total sheets passed with the Black/Color or Photo/Color cartridges, total waste ink absorbed, and the last three errors recoverable only by service personnel. Because the waste ink full error is based on the data of the total waste ink absorbed as stored in the EEPROM, the Waste Ink Counter must be cleared whenever the waste ink absorber has been replaced. If the control board has been replaced, the new EEPROM must also be initialized and the waste ink absorber replaced. 2.5 Setting the Model The control board of this printer is a common component for different printers. If you have replaced the control board, it is necessary to set the model setting as initial information. After selecting the model, by pressing the POWER button, the selection will be validated.
