A system comprising:
- a web moving in a first direction, the web comprising media and a printing liquid;
- a plurality of identical modules, each module comprising:
- a support located under the web, an area between the support and the web forming a gap with a height and length, wherein:
- the height being the separation of the support and the web,
- the length being in the first direction, and
- an air flow flowing the length of the gap, the air flow moving counter to the first direction;
- a microwave source to apply microwaves to the web;
- an ultraviolet (UV) source to apply ultraviolet light to the web;
- an infrared (UR) source to apply infrared light to the web;
- and
- and a reduced-pressure trap on an upstream side of the gap of a first module of the plurality of modules, the trap collecting material released from the web.
