Issue Nov 11 Technical Reference Manual 24.1 CYCLONE UNDER SCREEN CLEANER MODULE OVERVIEW The cyclone under screen cleaner wipes lint free paper, dry or wet across the underside of the screen to minimize paste build up The frequency and mode (wet/dry/vac) are programmable in the product file The under screen cleaner is available in three widths, 300, 400 and 515mm and is supplied with an extra paper cassette for a quick change-over when replenishment is required The paper cassette can be programmed to oscillate in the X direction creating a scrub action as the cleaner traverses in the Y direction When a screen cleaner operation is required, the camera carriage approaches the cleaner and attaches to the two cleaner camera magnets The two cleaner home magnets holding the screen cleaner unit in the home position are deenergized, the cleaner camera magnets are energized securing the cleaner to the camera beam, allowing the camera carriage to pull the cleaner across the screen The cleaner dropped sensor alerts the operator if the cleaner becomes disengaged from the camera carriage during cleaning A paper usage sensor enables the software to monitor the clean paper roll The paper feed motor supplies a clean section of paper across the vacuum chamber The external solvent tank, mounted on the rear or either side of the machine, is a container capable of accommodating a litre container of solvent A load cell in the base of the external solvent tank enables the software to calculate the percentage level of solvent within the container The solvent is pumped from the container by the solvent pump and is dispensed along the width of the paper by the solvent spray bar which is incorporated in the vacuum chamber The vacuum chamber is connected to a vacuum filtration unit which extracts the solvent fumes and draws excess print material onto the paper Vacuum Filtration The vacuum filtration unit fitted may be one of the following types: • VF35i Vacuum Filtration Unit • VF25 Vacuum Filtration Unit NOTE For information on the removal and replacement of the filters, refer to the Preventive Maintenance chapter of the Technical Reference manual VF35i Vacuum Filtration Unit VF25 Vacuum Filtration Unit 24.2 The onboard VF35i vacuum filtration unit is protected by two circuit breakers on the front panel of the base unit A 15A (for 110V) and an 8A (for 230V) which can be reset by pressing the circuit breaker button covered by a clear plastic protector For safety, the voltage selector control knob is removed from the switch and bolted to the fan housing The VF35i vacuum filtration unit has a three position mechanical air flow adjuster to regulate the air flow as follows: • Maximum (full air flow) • Medium (half air flow approximately) • Minimum (15% of full air flow approximately) The onboard VF25 vacuum filtration unit is protected by either an 8A (for 110V units) or 5A (for 230V units) slow blow fuse A spare fuse is provided in the retractable fuse clip sited under the mains socket of the base unit Technical Reference Manual Chapter Issue Nov 11 CYCLONE UNDER SCREEN CLEANER MODULE OVERVIEW Solvent Advice DEK only recommend the DEK-PRO and
