Outline of Operation, cont'd.
Operation of Pressure Mode
This operation will be executed during Cleaning 3 or Cleaning 4.
During the pressure mode, the open/close latch of the sub-tank is
opened, the pressure/release cam is pressurized with the suction
pump stopped, so that the suction pump is closed. When the
pressure pump executes pressure operation under this condition,
the ink is forcibly fed to the BJ head from the sub-tank and
exhausted out of the nozzle. The recovery pump executes the
suction operation to return the ink exhausted to the restoration tub
into the sub tank.
