Calibration apparatus is disclosed for a jet printer (10) including a recording medium support having a support surface, and at least one nozzle that is operative to emit an ink jet toward the support surface and is movable along the support surface in a translation direction. The apparatus includes a probe (14) positioned proximate the support surface that includes a plurality of edge portion pairs separated by different distances in a direction along the translation axis, and located at different distances along a test direction perpendicular to the translation direction and proximate the support surface. The apparatus also includes detection circuitry responsive to the probe, and calibration logic responsive to the detection circuitry and having a calibration result output. <IMAGE>
