A printing device has a motor that drives an ink jet print head back and forth along a print track. A service station is installed on one end of the print track, and has a first track, a second track, a slot track, and a wipe sled. The wipe sled slides inside a housing of the service station along the first track, in parallel with the print track. The slot track, which is part of the wipe sled, in diagonal to the print track. The second track, mounted on the housing, is perpendicular to print track. A wiper is mounted on both the slot track and the second track. The relative movement of the slot track with the second track as the wipe sled is pushed backwards forces the wiper into a working position.
