Abstract

A hardcopy device having a scanning head arranged to reciprocate across a scan axis, and first and second codestrips arranged substantially parallel to the scan axis, the first and second codestrips being offset from one another in the scan axis, such that the device may determine the position of the head along the scan axis relative to the first and second codestrips in a first set of positions but relative to only one of the first and second codestrips in a second set of positions.
