Abstract
Ink is sucked in a first amount from recording heads by applying negative pressure of suction pumps to the recording heads in a state in which communication between the recording heads and the atmosphere is cut off by sealing the recording heads by means of caps. The ink in the caps is then discharged by causing negative pressure of the suction pumps to act in a state in which the caps are made to communicate with the atmosphere, and then wiping is effected by a wiping blade.
