Printing system with adjustable aerosol collection
View Patent ↗A printing system that has a drive roller for feeding different sizes of media along a media path, an inkjet printhead assembly for printing the media and an ink aerosol collection system for removing ink aerosol from areas adjacent the media path. The ink aerosol collection system is configured to remove aerosol at a greater rate in response to an increase in the media size.
1. A printing system comprising:
a drive roller for feeding different sizes of media along a media path;
an inkjet printhead assembly for printing the media; and,
an ink aerosol collection system for removing ink aerosol from areas adjacent the media path; wherein,
the ink aerosol collection system is configured to remove aerosol at a greater rate in response to an increase in the media size.
2. A printing system according to claim 1 wherein the printhead assembly is positioned on a first side of the media path and the aerosol collection system has a first aerosol collection opening positioned on the first side of the media path and a second aerosol collection opening positioned on a second side of the media path.
3. A printing system according to claim 2 wherein the media path has a width corresponding to a maximum width of media that can be printed by the printing system and the aerosol collection system is configured to collect ink aerosol from the first and second aerosol collection openings when the media being printed is less than the maximum width.
4. A printing system according to claim 3 further comprising:
a platen for supporting the media during printing; wherein, the platen has a spittoon system for collecting non-printing drops of ink ejected from the inkjet printhead assembly.
5. A printing system according to claim 4 further comprising a plurality of service modules, wherein the printhead assembly has a plurality of separate printheads fixed relative to the media path and one of the service modules corresponding to each of the printhead respectively, the service modules being configured to operate in a spittoon mode to provide the spittoon system.
6. A printing system according to claim 5 wherein the printheads are arranged into a group of leading printheads and a group of trailing printheads, the leading printheads being upstream of the trailing printheads with respect to the media feed direction.
7. A printing system according to claim 6 wherein the first and second aerosol collection openings are downstream of the trailing printheads.
