A device for positioning an ink jet print head and a cleaning and sealing device may be used in a postage meter and/or addressing machine for print media guided along a printing window in a guide plate by a transport device. In order to improve printing quality, the print head stationarily disposed behind the guide plate and the printing window is adjustable out of a printing position to be set in a defined way, into a cleaning and/or a sealing position and back again, and a cleaning and sealing device adapted to the print head can be coupled to the print head in a positionally accurate and functionally appropriate manner. The print head is pivotably secured and the cleaning and sealing device is disposed behind the guide plate, but linearly adjustably toward and away from the print head. A common gear for adjustment of the print head and the cleaning and sealing device is driven by a motor running in only one direction of rotation. The print head, the cleaning and sealing device, the gear and the motor are combined into a compact structural group secured adjustably to the transport device.
