Abstract
In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.
Claims13
An aerosol control system for a printer, comprising:
- a vacuum duct through which air may be sucked away from a printed side of a substrate leaving a print zone;
- and
- a pressure duct, distinct from the vacuum duct, through which air may be blown on to the printed side of the substrate leaving the print zone, the pressure duct positioned downstream from the vacuum duct and configured to blow air diagonally upstream directly on to the substrate at the same location the vacuum duct is to suck air away from the substrate.
An aerosol control system for a printer, comprising:
- a vacuum duct through which air may be sucked away from a printed side of a substrate leaving a print zone;
- and
- a pressure duct, distinct from the vacuum duct, through which air may be blown on to the printed side of the substrate leaving the print zone, the pressure duct positioned downstream from the vacuum duct and configured to blow air diagonally upstream against a downstream side of the vacuum duct.
An aerosol control system for a printer, comprising:
- an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web;
- and
- a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow;
- and where
- an outlet from the air knife is downstream from an intake to the vacuum and configured to discharge the sheet of air diagonally upstream directly on to the substrate at the same location the vacuum is to suck up aerosol.
A process to control aerosol in a printer, comprising simultaneously sucking air away from a printed side of a substrate leaving a print zone and blowing air diagonally upstream directly on to the substrate at the same location air is sucked away from the substrate.
