CAUTION
n Use the transport liquid cartridges (x 6) for “Head Cleaning.” It

CHECK
PO INT
n When replacing the C299MAIN board, be sure to carry out
writing of the D/A correction values. This parameter is measured
during manufacturing of the circuit board, and is written to the
USB EEPROM on the board. This parameter exists in a Flash
ROM area that cannot be copied during parameter backup with
a PC card, so it should be carried out from the USB EEPROM on
the new board.
