Upon completion of purging, the machine automatically returns to the initial stage of
the maintenance mode.
Note • Before performing a purge operation, confirm that the ink cartridge that has
enough remaining has been installed or if there is enough remaining ink into the

• This machine counts all purge operations and flushing operations performed since
produced in order to prevent the ink absorber box and flushing box from
overflowing with drained and flushed ink, respectively.

appears on the LCD, and further purge or flushing operations are prohibited.
Replace the ink absorber box or flushing box and then reset the corresponding
