To achieve optimum productivity and security with numbering systems, you need more than the greatest possible number of servomotors. It is the perfect interaction of all components that makes the difference. Equipped with 12 number and letter wheels, the LENservo 12 marks up to 12,000 print sheets per hour at a top speed of 80,000 revolutions per minute and automatically sets a new security code every 80 milliseconds. After numbering, the banknotes no longer need to go through lengthy collection, but can proceed directly to further processing.
Since the number of moving parts has been reduced to a minimum, and sensitive components such as gears or electronic contacts have been entirely eliminated, the potential sources of error have also been reduced. A key prerequisite for the LENServo 12’s ability to reliably meet the high demands of a three-shift operation. But there is even more: during the development of the motor, we ensured that it would perform more quickly than standard printing presses, so that the numbering system would never lead to a production bottleneck.
A further advantage is that skip-control – via encoders on the servomotors and magnets on the mechanical wheels – guarantees zero-defect printing. And restarting after an error message is foolproof.

Maintenance and wheel replacement are much more convenient with the LENservo 12 than with conventional numbering systems. Thanks to the revolutionary and patented folding mechanism, the numbering system can be opened in just a few steps, and the complete wheel set can be removed and cleaned, while the electronic parts remain in the housing. This unique design significantly reduces both maintenance and set-up times. Additionally, the LENservo 12’s compact design reduces circumferential and axial distances to a minimum.
