Printer and dryer for drying images on coated substrates in aqueous ink printers

An aqueous ink printer comprising:

• at least one printhead configured to eject drops of an aqueous ink;
• a substrate transport system configured to move substrates past the at least one printhead to enable the at least one printhead to eject drops of the aqueous ink onto the substrates to form aqueous ink images on the substrates;
• a member that extends across the substrate transport system in a cross-process direction, the member being positioned in a process direction at a location after the at least one printhead ejects drops of aqueous ink onto the substrates;
• at least one roller that is mounted to the member and being positioned to contact the substrates on the substrate transport system after the at least one printhead has ejected drops of the aqueous ink onto the substrates, each roller in the at least one roller having a width in the cross-process direction that is less than a width of a single substrate in the cross-process direction and a total width of the rollers in the at least one roller is less than the width of the single substrate in the cross-process direction;
• a first drying stage configured to dry the substrates uniformly across the width of the single substrate after the at least one printhead has formed aqueous ink images on the substrates and before the substrates reach the at least one roller on the member;
• and
• a second drying stage positioned to dry the substrates non-uniformly across the width of the single substrate after the substrates have passed through the first drying stage and before the substrates reach the at least one roller on the member, the second drying stage being configured with at least one member extending in the process direction so the at least one member aligns with the at least one roller and a plurality of drying elements mounted to the at least one member, the plurality of drying elements being aligned with the at least one roller in the process direction and no portion of the plurality of drying elements is opposite any portions of the substrates that do not contact the at least one roller so the plurality of drying elements directs drying only at predetermined portions of the substrates that contact the at least one roller so the plurality of drying elements dries the predetermined portions of the substrates contiguously in the process direction.
