ABSTRACT:
Upon adjustment of an ink level of an air buffer in an ink supply system supplying an ink to a printing head via the air buffer from a sub-tank, by driving a pressuring motor of the sub-tank, the ink is fed under pressure. When the ink is reached at the position of a connection opening of the air buffer, the excess amount of ink is discharged for adjustment of the ink level. At this time, the ink discharged through the connecting opening is returned to the sub-tank via the ink tube. Thus, the ink consumed during the ink level adjustment can be avoided. With a construction set forth above, the shown case, the in the ink-jet cloth printing apparatus, in which the ink is supplied to the printing head via the air buffer, the ink amount to be consumed during the ink level adjustment of the air buffer is eliminated so that the ink consumption of the overall can be reduced.
