A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus

A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus includes a sheet guide having a guide surface disposed beneath the transfer area, and a pneumatic system for blowing a positive pressure air stream in the direction of a transfer area or tangent point between the sheet holding and transfer systems. A further pneumatic system optionally may be provided for drawing or blowing air through apertures in the guide surface.

The method of claim 4, wherein said predefined period of time is determined as a function of the type of particulate being collected.6. The method of claim 1, wherein the step of rinsing comprises utilizing a rinse liquid that is not toxic to biological particulates, said method further comprising the step of thus enabling a collected sample to be cultured to determine a result.7. The method of claim 1, wherein the step of rinsing comprises utilizing at least one of a rinse liquid that includes a surfactant to reduce a surface tension of said rinse liquid, and a heated rinse liquid, thereby increasing an efficiency with which particulates are rinsed from the combined impact collector and fan.8. The method of claim 1, further comprising the step of stopping the rotation of said combined impact collector and fan before the step of rinsing.9. The method of claim 8, further comprising the steps of removing said combined impact collector from a prime mover after stopping its rotation and before the step of rinsing.10. The method of claim 9, further comprising the step of providing a rinse station, wherein the step of rinsing comprises the step of placing said combined impact collector in said rinse station.11. The method of claim 10, further comprising the step of providing a rinse cassette, wherein the step of placing said combined impact collector into said rinse station comprises the steps of inserting said combined impact collector and fan into said rinse cassette; and then placing said rinse cassette in said rinse station.12. The method of claim 11, wherein the step of rinsing further comprises the step of rotating said combined impact collector and fan within said rinse cassette during rinsing, to aid in removing said particulates from said combined impact collector.13. The method of claim 11, wherein the step of rinsing further comprises the step of applying an ultrasonic pulse to said rinse cassette during rinsing, to aid in removing said particulates from said combined impact collector.14. The method of claim 1, further comprising the steps of providing a biocidal decontamination fluid; and flushing said combined impact collector and fan and said cavity with said biocidal decontamination fluid before the step of rotating said combined impact collector.15. The method of claim 14, wherein the biocidal decontamination fluid comprises at least one of a bleach solution, a hydrogen peroxide solution, a protein decomposing solution, and a nucleic acid decomposing solution.16. The method of claim 14, wherein the biocidal decontamination fluid comprises a fluid that does not interfere with a selected detection method.17. The method of claim 14, wherein the step of flushing comprises the step of flushing any fluid lines that are in fluid communication with said combined impact collector and fan and said cavity with the biocidal decontamination fluid.18. The method of claim 14, wherein the step of flushing comprises the step of collecting spent biocidal decontamination fluid produced by said step of flushing, in a spent biocidal decontamination fluid reservoir.19. The method of claim 14, further comprising the steps of providing a neutralizing fluid; and flushing said combined impact collector and fan and said cavity with said neutralizing fluid, after the step of flushing with said biocidal decontamination fluid, and before the step of rotating said combined impact collector.20. The method of claim 19, further comprising the steps of providing a sterile fluid; and flushing said combined impact collector and fan and said cavity with said sterile fluid, after the step of flushing with said neutralizing fluid, and before the step of rotating said combined impact collector.21. The method of claim 1, further comprising the step of enabling a user to selectively control a length of time during
