| 1. A positioning apparatus for a printer comprising:
at least one encoder;
an organic photoconductor (OPC) belt moved relative to the encoder and having a joint region; and
a code strip mounted on the OPC belt and having a plurality of bar codes, the encoder for detecting the bar codes and generating
a displacement signal representing a displacement of the OPC belt moved relative to the encoder, and thus a home position
is located by the displacement signal;
the code strip having a blank region adjoining the joint region.
