A wiper device of a printer has four wiper units arranged in a line to wipe the nozzle faces of an inkjet head. Each wiper unit has a first intermittent gear and a second intermittent gear which sequentially mesh with first and second drive gears and sequentially transverse axis X a wiping operation and a cleaning operation. The wipers move vertically to the nozzle faces. A wiper cleaner lever-rocks between a closed position covering the wiper and an open position not touching the wiper, moves through a path not interfering with the wiper in an opening operation, and through a path wiping the wiper and removing ink and other accretions from the wiper in a closing operation.
