  • Page 5: Important Notes

    1. Important Notes 1.1 Overview The ALS 321/421 is a fully automatic labeller. Operation is very easy and can be learned with a minimum of training. The machine is controlled by a microprocessor and because of its pro- grammable possibilities it can be used in many applications. Except for cleaning the rolls and light sensor there is no periodical maintenance necessary.
