Abstract
A position of a nozzle forming surface of a recording head is varied by an adjusting operation of a platen gap. Accordingly, an amount of interference (L L ) of a wiping member ( ), which wipes the nozzle forming surface ( ), against the nozzle forming surface ( ), varies. With this, a sliding contact of the wiping member ( ) against the nozzle forming surface ( ) varies. When the platen gap is large, the wiping effect decreases. Accordingly, when the platen gap is large, the wiping speed is decreased, and the decrease of the wiping effect is compensated for by increasing the number of wiping operations.
