Non-leaching cooler belt

A duplex printing system comprising:

• an image receiving member;
• an actuator operatively connected to the image receiving member to rotate the image receiving member;
• a marking unit including at least one printhead, the marking unit being configured to eject aqueous ink drops onto the image receiving member;
• a first cooling roll;
• a first transport belt that is in contact with a portion of an outer surface of the first cooling roll to substantially sandwich individual sheets of image receiving media between the first cooling roll and the first transport belt with a first surface of the individual sheets of image receiving media facing the first cooling roll;
• a second cooling roll positioned downstream of the first cooling roll in a process direction;
• a second transport belt that is in contact with a portion of an outer surface of the second cooling roll to substantially sandwich the individual sheets of image receiving media between the second cooling roll and the second transport belt with a second surface of the individual sheets of the image receiving media facing the second cooling roll wherein the first and second transport belts comprise:
• a bottom layer of woven or non-woven fibers;
• an optional intermediate adhesive layer;
• and
• a top rubber layer, wherein the second transport belt is operatively connected to a transfix belt actuator to move the top rubber layer of the second transport belt into and out of engagement with the individual sheets of image receiving media, and a rubber of the top rubber layer is selected from the group consisting of:
• nitrile butadiene rubber (NBR), ethylene propylene diene monomer rubber (EPDM) and fluoro elastomer;
• and
• an invertor;
• and wherein
• no unreacted contaminants leach from the first transport belt or the second transport belt.

A substrate cooling unit for use with a duplex aqueous ink jet image forming device, comprising:

• a first cooling roll;
• a first transport belt that is in contact with a portion of an outer surface of the first cooling roll to substantially sandwich individual sheets of image receiving media between the first cooling roll and the first transport belt with a first surface of the individual sheets of image receiving media facing the first roll;
• a second cooling roll positioned downstream of the first cooling roll in a process direction;
• a second transport belt that is in contact with a portion of an outer surface of the second cooling roll to substantially sandwich the individual sheets of image receiving media between the second cooling roll and the second transport belt with a second surface of the individual sheets of the image receiving media facing the second roll wherein the second transport belt comprises:
• a bottom layer of woven or non-woven fibers;
• an optional intermediate adhesive layer;
• and
• a top rubber layer, wherein the second transport belt is operatively connected to a transfix belt actuator to move the top rubber layer of the second transport belt into and out of engagement with the individual sheets of image receiving media, and a rubber of the top rubber layer is selected from the group consisting of:
• nitrile butadiene rubber (NBR), ethylene propylene diene monomer rubber (EPDM) and fluoro elastomer;
• and
• an invertor;
• and wherein
• no unreacted contaminants leach from the first transport belt or the second transport belt.
