When mounted to a vehicle, a dispenser ejects optical elements so that they have a component of movement that is parallel with the surface of the pavement to which the optical elements are to be applied. Preferably, the component of movement in that direction is more significant than a component of movement directly toward the pavement surface. A fluid assist causes the optical elements to be ejected from the dispenser nozzle at a velocity to at least partially counteract, and preferably match, the forward velocity of movement of the vehicle to which the dispenser is attached. Thus, in accordance with one specific aspect of the present invention, optical elements can be laid down upon marking material that has been applied to a pavement surface at a substantially reduced relative velocity to the road surface. By more closely matching the optical element velocity in a direction opposite the vehicle movement to the velocity of the vehicle, the optical elements can be laid down without substantial roll along the pavement marking material. This can be accomplished regardless of the size or mass of the optical elements. The result is that the retroreflectivity of the pavement marking is thus not compromised or negatively affected in either direction (i.e. in the direction of vehicle travel or in the opposite direction).

The apparatus of claim 7, wherein the marking device includes an ink-jet printhead. 11. A method for determining and eliminating flyers in a printing apparatus, comprising: measuring each sheet position at a first sensor, wherein the first sensor outputs first position signal to a controller; determining sheet position and sheet variance based on first position signal; comparing sheet variance to a running average sheet variance to determine whether the sheet is a flyer; and calculating new average sheet position based on said comparison for marking images on sheets. 12. The method for determining and eliminating flyers in a printing apparatus as in claim 11, further comprising: measuring each sheet position at a second sheet sensor, wherein the second sensor outputs second position signal to the controller; determining sheet shift position and sheet shift variance based on first position signal and second position signal; comparing sheet shift variance to a running average sheet shift variance to determine whether the sheet is a flyer; and calculating new average sheet shift position based on said comparison for marking images on sheets. 13. The method for determining and eliminating flyers in a printing apparatus as in claim 12, wherein the step of calculating new average sheet shift position, comprises: if the sheet is a flyer, identifying whether an immediately previous sheet passing the second sensor was determined to be a flyer and, if so, calculating the new average sheet shift position from the sheet shift position, a shift position of the previous sheet passing the second sensor and a predetermined number of shift positions of sheets which passed the second sensor. 14. The method for determining and eliminating flyers in a printing apparatus as in claim 11, wherein the step of calculating new average sheet position, comprises: if the sheet is a flyer, identifying whether an immediately previous sheet passing the first sensor was determined to be a flyer and, if so, calculating the new average sheet position from the sheet position, a position of the previous sheet passing the first sensor and a predetermined number of positions of previous sheets which have been measured at the first sensor. 15. A system for determining and eliminating flyers in a printing apparatus, comprising: a sensor for measuring sheet position, wherein the sensor outputs a position signal; and a controller receiving the position signal, the controller determining sheet position and sheet variance based on the position signal, comparing sheet variance to a running average sheet variance to determine whether the sheet is a flyer, and calculating new average sheet position based on said comparison for marking images on sheets. 16. The system for determining and eliminating flyers in a printing apparatus as in claim 15, further comprising: a second sheet sensor for measuring sheet position, wherein the second sensor outputs a second position signal to the controller; wherein the controller further determines sheet shift position and sheet shift variance based on the position signal and the second position signal, compares sheet shift variance to a running average sheet shift variance to determine whether the sheet is a flyer, and calculates new average sheet shift position based on said comparison for marking images on sheets. e motor M1 and the light 4 to operate and the timer circuit 3 causes the light 4 to remain lit for a predetermined amount of time after either (1) the switch 6 has been activated or (2) the switch 6 has been deactivated subsequent to being activated.
