Notes:

• First, install the printer driver via a USB connection.
• While the firmware is being updated, do not turn off the printer, try to access it through the network or try to print.
• If an error occurred during the update operation or if the operation was not completed successfully, try performing the operation again from the beginning.
  If the update operation cannot be completed successfully after multiple attempts, check the printer driver settings and the cable connections.
• The customer assumes full responsibility for performing the update operation.
