Mobius combination of reversion and return path in a paper transport system

A method of reverting a substrate in a substrate process apparatus comprising the steps of:

• transporting the substrate in a first direction along a first path;
• processing a first surface of the substrate in a processing station;
• decelerating the substrate along the first path;
• transporting the substrate in a second direction along a reversion path;
• reverting the substrate in a reversion module in the reversion path wherein the revision is not discontinuous from the first path;
• decelerating the substrate along the reversion path;
• merging the substrate into the first path;
• and
• processing a second surface of the substrate in the processing station.

A mobius pathway reversion module for an electrographic system comprising:

• an input pathway for receiving a substrate having a leading edge in a process direction;
• a reversion pathway for reverting the substrate with the leading edge in the process direction;
• a first merge point for merging the substrate into the reversion pathway from the input pathway with the leading edge in the process direction;
• and
• a second merge point for merging the substrate from the reversion pathway into the input pathway with the leading edge in the process direction, wherein the first merge point and the second merge are not discontinuous with the reversion pathway.
