Canon MP610 Error 6800

According to the service manual an error has occured writing to the eeprom on the logic circuit board. I would look at the logic board as a culprit . You may need to check the voltage is correct at the power point and matches the printer required supply voltage. What worries me is what caused the logic board to fail and make a burning smell. Could be a faulty voltage regulator supplying the logic board or a fault in a power board..

My Canon MP530 is giving 6A00 error message and alarm light is flashing along with copy button. i have replaced empty ink cartridges with new ones. Can anyone help, please?

Error code 6A00 indicates an error occurred in the AP motor during purging operation. You need to replace sheet feed unit, logic board assy and purge unit to fix it. Before replacement of the logic board assy, check the waste ink amount (by service test print or EEPROM information print). If the waste ink amount is 7% or more, also replace the ink absorber kit when replacing the logic board assy.

Error code 5010

Error code 5010 indicates carriage lift mechanism error. That means that the carriage did not move up or down properly. You need to replace PR lift shaft ***'y (QL2-0936), Sheet feed unit (QM2-2916), Logic board ***'y (QM2-3078), Carriage lift sensor unit (QM2-3092). In brakets you have the part number for each one of them. Before replacement of the logic board ***'y, check the waste ink amount (by service test print or EEPROM information print). If the waste ink amount is 7% or more, also replace the ink absorber kit (QY5-0146) when replacing the logic board ***'y.

Error 950.10 NVRAM mismatch. how do I fix or

The way that I have found to fix this problem is to replace the logic board but when you do that, this is where the NVRAM mismatch comes in. Once you change the logic you also have to change the display op panel. That is what is giving you this error. You must change logic and op panel at same time and it will not give that error.
